UserControl javascript: get control by id

Hi,

I have a UserControl with two labels and a slider control on it. I have a javascript function that is called when the value of the slider changes, and it is supposed to update the text of the labels.

The ascx code is:

asp Code:

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="AlignSlider.ascx.vb" Inherits="F1TimeTrials.Controls.AlignSlider" %>
<%@ Register assembly="Infragistics35.Web.v10.2, Version=10.2.20102.1011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.EditorControls" tagprefix="ig" %>
 
<script type="text/javascript" id="igClientScript">
<!--
 
    function sliderControl_ValueChanged(sender, eventArgs) {
        var leftLabel = document.getElementById('<%= Me.lblLeftValue.ClientID %>');
        var rightLabel = document.getElementById('<%= Me.lblRightValue.ClientID %>');
 
        var maxValue = sender.get_maxValueAsDouble();
        var value = eventArgs.get_newValue();
        leftLabel.innerHTML = value;
        rightLabel.innerHTML = maxValue - value;
    }// -->
</script>
 
<asp:Table ID="table" runat="server">
    <asp:TableRow runat="server">
 
        <asp:TableCell runat="server">
            <asp:Label runat="server" ID="lblLeftValue" Text="0" />
        </asp:TableCell>
 
        <asp:TableCell runat="server">
            <ig:WebSlider ID="sliderControl" runat="server" ValueType="Double" >
                <ClientEvents ValueChanged="sliderControl_ValueChanged" />
            </ig:WebSlider>
        </asp:TableCell>
 
        <asp:TableCell runat="server">
            <asp:Label runat="server" ID="lblRightValue" Text="100"/>
        </asp:TableCell>
 
    </asp:TableRow>
</asp:Table>

When I put this control on a page it works just fine. I drag the slider, the labels update with the new values.


However, I actually need a large number of these controls on my page (around 10-20 I think), and this is where the problems start. When I change the slider on one of these UserControls, it changes the text of only the labels in the LAST instance of this UserControl on the page. It seems that the 'document.getElementById' function actually searches through the entire page rather than just the one UserControl.

How can I fix this? How can I get the two label controls from this current UserControl instance, and not any other instance on the page?

is all the labels has the same id's ?

I don't know what you mean. My UserControl has two labels as you can see, one called lblLeftValue and one lblRightValue. I am simply putting multiple of these UserControls on one page.

yea, but my guess is that these lines:

Code:

---

  var leftLabel = document.getElementById('<&#37;= Me.lblLeftValue.ClientID %>');
  var rightLabel = document.getElementById('<%= Me.lblRightValue.ClientID %>');

---

get the id's of the last two labels in the page (check out the markup)

what you need to do is to pass the labels id's of the target control each time you call the sliderControl_ValueChanged method.
there are number of ways to do so, the easiest way is using jQuery but no doubt you can do it with native js, if you using .NET FW 4 you can control how the ids of your controls is rendered and use the Predictable value of the ClientIDMode property otherwise you can just check the markup and see how the the labels is been rendered.

if you still need help please paste to here the html markup

But the labels are on the UserControl! How can I pass in the 'target control' (that would be the current instance of that UserControl) if I am in that UserControl... The only reference I can think of is "Me" and I'm already using that.

can you please post the html markup? and... can you get the control id with the sender object?

try this inside the javascript method

alert(sender.id);

Hey,

Regardless of the number of the UserControls that get placed on the place, the ClientID of the controls on the page should all be unique. Typically, this means that the name of the parent control will be appended to the front of the label controls within the page.

Nick, as a first step, add two user controls to your page, and then inspect the HTML. Are you getting unique ID's for each of the two labels within the user controls?

Gary

Ok, I placed three sliders on a test page. Two of them (slider1 and slider2) are NormalSliders, and one if them is a BallastSlider. The difference is minimal, both of them are very similar UserControls with two labels and a WebSlider third party control. The difference is their min/max values and their stepsize (and the fact that one label is hidden for the NormalSlider). You may remember this from my other thread where I tried to let the different sliders inherit one UserControl but I ditched that idea (since it isn't working..) and just made three separate UserControls.

The aspx code:

asp Code:

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="SliderTest.aspx.vb" Inherits="F1TimeTrials.SliderTest" %>
 
<%@ Register Src="~/Controls/NormalSlider.ascx" TagName="NormalSlider" TagPrefix="uc" %>
<%@ Register Src="~/Controls/BallastSlider.ascx" TagName="BallastSlider" TagPrefix="uc" %>
<%@ Register Src="~/Controls/BrakeBalanceSlider.ascx" TagName="BrakeBalanceSlider" TagPrefix="uc" %>
 
 
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
 
    <!-- ScriptManager required for the WebSlider third party control -->
    <asp:ScriptManager runat="server">
    </asp:ScriptManager>
 
    <!-- Slider: -->
    <uc:NormalSlider runat="server" ID="slider1" />
    <uc:NormalSlider runat="server" ID="slider2" />
    <uc:BallastSlider runat="server" ID="ballastSlider" />
 
</asp:Content>

And the resulting HTML is attached because it is way too large.

It's quite a lot, probably because the sliders consist of separate images too make them look nice I guess, but the one thing I can see is that the label names in the javascript do indeed refer to the parent UserControl. For example, in the second slider UserControl javascript code I can spot

Code:

---

        var leftLabel = document.getElementById('ctl00_MainContent_slider2_lblLeftValue');
        var rightLabel = document.getElementById('ctl00_MainContent_slider2_lblRightValue');

---

This is slider1 and ballastSlider for the other two, so I'm a little mystified why it still updates the last labels only...

poops?

in your case this

Code:

---

var leftLabel = document.getElementById('<&#37;= Me.lblLeftValue.ClientID %>');
  var rightLabel = document.getElementById('<%= Me.lblRightValue.ClientID %>');

---

won't work, cause you need to use multiple controls in your page.
what you need to do is to get first the control id which i beleive you can get it with the sender object (did you tried what i wrote in my other post?)
and then use it as the label id, it should be something like this:

if the control id is: ctl00_MainContent_slider2_table
then this is how you'll get the wanted labels IDs:

Code:

---

<script type="text/javascript" id="igClientScript">
<!--

    function sliderControl_ValueChanged(sender, eventArgs) {

        var objectID =  sender.id;
      var leftLabelID = objectID.substring(0,26) + 'lblLeftValue';
      var rightLabelID = objectID.substring(0,26) + 'lblRightValue';
        var leftLabel = document.getElementById(leftLabelID );
        var rightLabel = document.getElementById(rightLabelID);

        var maxValue = sender.get_maxValueAsDouble();
        var value = eventArgs.get_newValue();
        leftLabel.innerHTML = value;
        rightLabel.innerHTML = maxValue - value;
    }// -->
</script>

---

Hmm I will try that later, but it doesn't seem like a very solid approach. Substring(0, 26)..? What if the control name ctl392 or whatever? Then that will go wrong already. There must be a simple way to get the label on the current UserControl instance :/

I noticed the sender object in the function. Did you try to use that client id ?

Quote:

---

function sliderControl_ValueChanged(sender, eventArgs)

---

This is the reason i would use jQuery for this task, until FW 4 ASP.NET developers had really big problem with html elements IDs when javascript was involved, i did suggest in early posts to set the clientidmode to Predictable, anyways the method i suggested is not very "good looking" but it will work flawless because of the single fact that the label controls id and the slider controls id will always start the same and only end differently.

one more thing i want to add, i suggest you'll advice the control documentations to see if they have something built in for this situation

I would suggest to view the source of page and see the id of the control.

The sender is the object that called the javascript function, eg the WebSlider third party control. I dunno what that helps me retrieve the labels. The only connection the labels and the WebSlider have is that they are on the same UserControl.

what you have here is pretty simple task which i face a lot, the info we post in this thread is more then enough to solve it and make it work.

Ok, I still don't get it... sender.id doesn't work, if I put that in an alert it tells me 'undefined'.


Let's make it easier, forget about the sliders. Here's a much simpler UserControl: a Button and a label. When the button is clicked, it adds a | character to the label, so you can see how many times it's been clicked:

asp Code:

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="ButtonUserControl.ascx.vb" Inherits="F1TimeTrials.ButtonUserControl" %>
 
<script type="text/javascript">
    function buttonClicked() {
        var label = document.getElementById('<%= Me.label.ClientID %>');
        label.innerHTML += '|';
        return false;
    }
</script>
 
<asp:Table runat="server">
    <asp:TableRow runat="server">
        <asp:TableCell runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked();" /></asp:TableCell>
        <asp:TableCell runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

Now put two of these on a page:

asp Code:

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="SliderTest.aspx.vb" Inherits="F1TimeTrials.SliderTest" %>
 
<%@ Register Src="~/Controls/ButtonUserControl.ascx" TagName="ButtonUserControl" TagPrefix="uc" %>
 
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
 
    <uc:ButtonUserControl runat="server" />
    <uc:ButtonUserControl runat="server" />
 
</asp:Content>

Click both buttons. As you can see, both buttons add | characters only to the LAST UserControl's label.

Could you show me how I can fix this? There is no sender in this case (at least I don't think so?), all I have is the current UserControl instance, and I would expect "Me.label.ClientID" to return the correct label's ID and not the ID of the last label, irregardless of which UserControl instance it is on...


EDIT
The resulting HTML contains this:

Code:

---

<script type="text/javascript">
    function buttonClicked(sender) {
        alert(sender);
        var label = document.getElementById('ctl00_MainContent_ctl00_label');
        label.innerHTML += '|';
        return false;
    }
</script>

<table>
        <tr>
                <td><input type="submit" name="ctl00$MainContent$ctl00$button" value="Click!" onclick="return buttonClicked();" id="ctl00_MainContent_ctl00_button" /></td><td><span id="ctl00_MainContent_ctl00_label"></span></td>

        </tr>
</table>
   

<script type="text/javascript">
    function buttonClicked(sender) {
        alert(sender);
        var label = document.getElementById('ctl00_MainContent_ctl01_label');
        label.innerHTML += '|';
        return false;
    }
</script>

<table>
        <tr>
                <td><input type="submit" name="ctl00$MainContent$ctl01$button" value="Click!" onclick="return buttonClicked();" id="ctl00_MainContent_ctl01_button" /></td><td><span id="ctl00_MainContent_ctl01_label"></span></td>
        </tr>
</table>

---

In the first script, it references the first label. In the second script, it references the second label. Yet, it always changes the second label.... ***?

one sec i'm making an example

ok here is working example:

user control:

Code:

---

<script type="text/javascript">

    function buttonClicked(obj) {
        var objectID = obj.id;
        var labelID = objectID.substring(0, 31) + 'label';
        var label = document.getElementById(labelID);
        label.innerHTML += '|';
        return false;
    }
</script>

<asp:Table ID="Table1" runat="server">
    <asp:TableRow ID="TableRow1" runat="server">
        <asp:TableCell ID="TableCell1" runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked(this);" /></asp:TableCell>
        <asp:TableCell ID="TableCell2" runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

---

default.aspx content (inside master page)

Code:

---

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
        <uc1:ButtonUserControl  ID="ButtonUserControl1" runat="server" />
        <uc1:ButtonUserControl ID="ButtonUserControl2"  runat="server" />
</asp:Content>

---

few things to note:
A) you should write the JS function outside the usercontrol because then you get multiple identical function which could lead to problems.

B) i too don't like the substring method but it work, again use jQuery selectors which make js + asp.net very easy or upgrade to FW 4.0 and then you can control of how your html elements be rendered ...


you should

Could you explain how to use jQuery and/or FW 4.0? I think I have both... I don't like to use the substring approach (unless it is common practice?!) as it just seems very 'unstable' and might break at any time if I change something... The number 31 for example, why is it 31 while it was 26 last time? How do you know that it will be 31 always?

as long you won't change the page hierarchy it will stay the same.

what version of .NET are you use ?
and for jquery, let me prepare you an example.

I'm using .NET 4.0 of course otherwise I wouldn't ask for a 4.0 example :p

this is jQuery example:

Code:

---

<script type="text/javascript">

    function buttonClicked(obj) {
        var label = $(obj).parent().parent().find('span:eq(0)');
        label[0].innerHTML += '|';
        return false;
    }
</script>

<asp:Table ID="Table1" runat="server">
    <asp:TableRow ID="TableRow1" runat="server">
        <asp:TableCell ID="TableCell1" runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked(this);" /></asp:TableCell>
        <asp:TableCell ID="TableCell2" runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

---

i only changed the javascript function (you must add jQuery library to use it: http://www.jquery.com

the first line does all the job let me explain

Code:

---

        var label = $(obj).parent().parent().find('span:eq(0)');

---

obj is the button instance, the button element is child of table cell and the table cell is the child of table row and the label is actually a span element inside another table cell
so with jquery selector you can drill upword to the table row and then use the
.find() method to get to the first span elements ":eq(0)" selects the first one

do you still need FW 4 example ?

Doesn't seem to work, when I put an alert after the 'var label =' line it never reaches it. Do I have to install jQuery or something? I automatically get a folder Scripts with some jQuery files in it in my project so I assumed it was ok..?

did you added reference to the jquery file inside the head tag:

Code:

---

    <script src="<jQuery Path Goes Here>/jquery.js" type="text/javascript"></script>

---

I didn't.

I tried adding it in the UserControl:

Code:

---

<&#37;@ Control Language="vb" AutoEventWireup="false" CodeBehind="ButtonUserControl.ascx.vb" Inherits="F1TimeTrials.ButtonUserControl" %>

<script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

<script type="text/javascript">
    function buttonClicked(sender) {
        var label = $(obj).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }
</script>

<asp:Table runat="server">
    <asp:TableRow runat="server">
        <asp:TableCell runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked(this);" /></asp:TableCell>
        <asp:TableCell runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

---

When I run this and click the button, there's no alert and the page posts back (so return false is never reached I guess). Doesn't work.

So I tried it on the page instead:

Code:

---

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="SliderTest.aspx.vb" Inherits="F1TimeTrials.SliderTest" %>

<%@ Register Src="~/Controls/ButtonUserControl.ascx" TagName="ButtonUserControl" TagPrefix="uc" %>


<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
   
<script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <asp:ScriptManager runat="server" />

    <uc:ButtonUserControl runat="server" />

</asp:Content>

---

Now, still no alert, but the page no longer posts back. This is a little strange to me... If it doesn't post back then it has reached return false right? But why then is there no alert? And no extra |...?


I don't get it, why is this so hard? When I search for 'multiple user controls' I get at least 5-6 results with people having the exact same issue, but all they got was a few vague hints but no real solution... I don't understand how something this fundamental can be so difficult to accomplish :s

change this bolded line:

Code:

---

function buttonClicked(sender) {
        var label = $(obj).parent().parent().find('span:eq(0)');
        alert('jup');
      label[0].innerHTML += '|';
        return false;
    }

---

it still strange that there is no alert but try it anyway

Doesn't help.

Can you show me the FW4.0 method..? I'm just about ready to give up on ASP.NET...

you should be more stubborn, if something not work and it should you really try to find the reason of why it's not working, anyway in FW 4 every control has the property ClientIDMode, you can set its property to
predictable and then use the first method i showed you but without the substring but using its index.

now, if this makes you wanna quit ASP.NET then you really should cause there are a lot more to come, unlike win apps (win forms) web developers need to deal with browsers compatibility, master lots of languages (c#/vb,js,css,html,sql,jq,ajax,linq) and more... my advice don't quit, you just might trying something that is bit advanced for you at the moment, keep learning and i'm sure you'll get there quickly.

The ClientIDMode doesn't need to be set to Predictable, as its default is Inherit and the page (from which it inherits) should default to Predictable. So, if my logic is correct, it should already be Predictable by default.

It makes me want to quit ASP.NET because it simply isn't logical. If I get the ClientId of Me.lblLeftValue then it should return the ClientId of Me.lblLeftValue, and not of some other label on the page. That just makes absolutely no sense to me.

If i'm not mistaken the default clientidmode is AutoID.
and what happen to you makes a lot of sense, each control have to have unique ID so if you have two labels each of of them got to have its own ID, when working on the client side (javascript) you don't have the benefits of working on the server side where the compiler do the job for you and find the correct id for you just by using the original id name of the control

But look at the HTML I posted a few posts back. The labels do have unique IDs. The first one is called ctl00_MainContent_ctl00_label, and this is also what it says in the first javascript code. The second one is called ctl00_MainContent_ctl01_label and that's also what it says in the second javascript code.

And from MSDN:

Quote:

---

The default value of ClientIDMode for a page is Predictable. The default value of ClientIDMode for a control is Inherit. Because the default for controls is Inherit, the default generation mode is Predictable. (However, if you use Visual Studio to convert a Web project to ASP.NET 4 from an earlier version, Visual Studio automatically sets the site default to AutoID in the Web.config file.)

---

As far as I know I didn't convert my project, I just started a new Web Application in ASP.NET 4, so my default ClientIDMode should be Predictable.

yes the labels do get unique ids and this is the reason you can't use the same id name for each label.

the blame for you problem is the author of the control you're using, he/she should have supply methods to handle this situation.

my advice is you won't give up using jQuery, I checked the example that i posted here and it's working beside that jQuery will help you a lot more along the way.

if you're using firefox d/l firebug plugin this is great tool for debugging javascript errors, if you're using ie or chrome they both have js debugger as well, but i still go with firebug.

you can post here the exact code that don't works for your with jquery and i'll try to recreate the problem.

Ok, I am trying to play catch up with this thread, and I am failing...

Where exactly are we at? Nick, can you post a sample of the application as it stands, so that we can try and help?

Also, I would strongly encourage you not to give up on ASP.Net. I agree that some things don't make sense at the start, but a lot of that will be because you come from a Windows Application background, and the paradigms are completely different.

Stick with it!

Gary

I am still stuck at post 27 I guess. Trying to have a Button click add a | character to a label. The code you see there is, as far as I can see, identical to what motil gave me, yet it's not working. The page does not post back (good), but the alert does not show and the | doesn't come up.

bhaa..

Nick i just re-checked your code.. the reason it's not working for you is that you changed the parameter name but didn't changed it inside the code look:

Code:

---

  function buttonClicked(sender) {
        var label = $(obj).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }

---

decide how you wish to call it "obj" or "sender" but it must be the same..
this is why you need js debugger btw..

Hello there,

Try this:

Code:

---

<script type="text/javascript">
    function buttonClicked(sender) {
        alert("hi");
        var label = $(sender).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }
</script>

---

Gary

Damn your fast fingers motil.... :)

haha :D

Nick,

As you will see, I put an extra alert in the code, on the very first line.

This meant that I could see that at the very least, the function was getting called. From there, given that there is another alert directly after the offending line, it narrowed down what was happening. Then, on looking at the line, I thought about what could be causing the problem.

Then I tried this:

Code:

---

alert($(obj));

---

I tried this (my jQuery isn't that hot, and I wondered if motil was trying to work magic) and when that didn't return anything, I knew that this was the culprit.

From there, it was a short step to do this:

Code:

---

alert($(sender));

---

And when that returned an HtmlElement, I altered the code as above.

I hope that little explanation helps.

Gary

Sorry, I dunno why I wrote that, it's correct in my code:

asp Code:

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="ButtonUserControl.ascx.vb" Inherits="F1TimeTrials.ButtonUserControl" %>
 
<script type="text/javascript">
    function buttonClicked(sender) {
        var label = $(sender).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }
</script>
 
<asp:Table runat="server">
    <asp:TableRow runat="server">
        <asp:TableCell runat="server"><asp:Button runat="server" ID="button" Text="Click!" OnClientClick="return buttonClicked(this);" /></asp:TableCell>
        <asp:TableCell runat="server"><asp:Label runat="server" ID="label" Text="" /></asp:TableCell>
    </asp:TableRow>
</asp:Table>

Still nothing. No alerts, no post-backs, no | characters.

I tried debugging with Firebug but unless I'm doing it wrong even that isn't working. I just go to the sripts tab, find the piece of javascript, put a breakpoint beside it, but it doesn't hit when I click the buttons.

It does hit suddenly when I refresh the page. Then I also get the option like Run, Step Into, Step Over, etc, but whatever I do (step into, over, out) it just seems to skip the entire code in the function. The breakpoint is on the function declaration ("function buttonClicked(sender)").

EDIT
And when I put an alert on the very first line of the function it does show, so the function is getting called OK.

EDIT2
When I try this javascript, only 'hit' is shown:

javascript Code:

<script type="text/javascript">
    function buttonClicked(sender) {
        alert('hit');
        alert($(sender));
 
        var label = $(sender).parent().parent().find('span:eq(0)');
        alert('jup');
        label[0].innerHTML += '|';
        return false;
    }
</script>

EDIT3
When I alert just 'sender' it shows me something like object HTMLElement so it's not null.

Ok, put an alert before the "var label" line, does that get hit?

I literall took your code from post #27, pasted into a new user control, added the user control to a page, and away it went.

Gary

yep you doing something wrong, i copied the exact code you posted and its working without changing single character ...

in firebug script tab, did you made sure thet it's enabled ?
when you selecting the script tab there is little down arrow, press it and make sure it's enabled ..

again, i copied the exact code you posted and it's working on my system.

Nick, again, in order to avoid something simple that is being missed in translation, can you upload a sample application that isn't working and we can take a look?

Gary

I guess the jQuery thing isn't working, because it seems that 'sender' is not null while $(sender) is... Or at least, it doens't show an alert if I use $(sender).

Project is attached.

Ok, this is an issue with this line:

Code:

---

<script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

---

Use this:

Code:

---

<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>

---

Instead, and it will work.

Gary

yep jQuery is was not enabled.

because of this "~":

  <script src="~/Scripts/jquery-1.4.1.js" type="text/javascript" />

change it to this:

Code:

---

      <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>

you can use the "~" sign only when using ASP.NET controls that has runat="server" attribute

otherwise just use the slash "/" has the web directory

you win this time gap :)
it took me time to explain in details :)

Ha ha.

Yeah, I probably should have provided details.

Nick, if you drag the .js file from the Solution Explorer into the ASPX/ASCX window, the correct path will be created for you.

again, do not drag js files or define function / js inside your user control, because once you load multiple instances of that usercontrol you also double your js functions / js code, instead create global js file and add reference to the master page (or to the default.aspx file if you're not using master page)

Ah, very good point.

If you intend on having multiple user controls on the page, then defining the JS include at the highest level makes sense.

The only time I would go ahead this is if you have a very large JS file, that is only used in the user control, and you only intend on using the user control one at a time, that I would say put it in there.

Thanks, it finally seems to work ok. I'll go try it out on the slider controls.

Hm, the sliders stopped working completely. It's probably an unrelated issue but I've got no time to figure it out now so I'll get back to this probably tomorrow.

ok just remember that the jquery I posted probably won't work right a way with the slider control you got there, adjustments should be made.

just post here the html markup of a single control and i'll post the correct jq syntax.

Yeah I figured as much, as the slider is visually quite 'enhanced', contains lots of images and stuff like tickmarks that are probably 'labels' too. But even a separate WebSlider (completely without any of this javascript or even any labels beside it) has stopped working, so I probably broke something else somewhere...

ok, we here if you need any farther help.
