[RESOLVED] Want GridView Hyperlink to open window

[MMock]

I've been hacking and googling for a while now, I guess it's time to ask the experts.

I have a link in my gridview that when clicked should open a popup window. I want scrollbars, a menubar and it should be sizable. So this is what I have. It is not working. You click the link and nothing happens.

                <asp:TemplateField HeaderText="Est. Total">
                    <ItemTemplate>
                    <asp:HyperLink 
                             ID="hyEstTotal" runat="server" 
                             Text='<%# String.Format("{0:c}", Eval("total")) %>'
                             >
                    </asp:HyperLink>
                    </ItemTemplate>
               </asp:TemplateField>

And the code-behind:

                Dim hyEstTotal As HyperLink = DirectCast(Me.GridView1.Rows(idxGrid).FindControl("hyEstTotal"), HyperLink)

                hyEstTotal.NavigateUrl = _
                    "javascript:popUp('show_estimate.aspx?ID=" + CStr(ds.Tables(0).Rows(idxData).Item("invoice_id")) + "', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');"

The link looks fine, it is being generated exactly as it should, it just doesn't...link.

Thanks.

I lied.

I had so many darn IE windows open that I didn't see that my popup window was opening.

However, the main thing I am trying to accomplish is to get the scrollbars and I do not have them. It is sizable and I have the menubar but I don't have scrollbars. My grid is overlapping off the window and I have to maximize to see it but that's still not all of it.

What am I doing wrong?

[riteshjain1982]

Try using windows.open method in that u can specify the features of the pop-up page like

"'width=750,height=500,left=100,top=80,location=no,menubar=yes,resizable=yes,scrollbars=yes,status=yes,titlebar=yes,toolbar=yes'"

[MMock]

Thank you for the reply. I thought I was doing that. Did you scroll my code all the way over to the right? I'm not sure what you're suggesting that's different from what I am already doing. Thanks.

[Harsh Gupta]

Is popUp() in your code a JS function?

[riteshjain1982]

hmmm i overlook that

btw just give it a try with windows.open, as mentioned above even i am not aware about popup()

window.open('" & sUrl & "',''," & sFeatures & ");

[MMock]

Harsh and riteshjain1982:

popUp was in my javascript. I did as riteshjain1982suggested and am using open.window instead. It works but there's still no scrollbars. Plus this odd behavior: On the page where I clicked in the gridview, that page loses all its contents and displays the word [object] instead. That's it for the whole page. (I believe this was happeninig with popUp also).

I hope this isn't another weird problem I'm so good at getting myself into...

Thanks.

[Harsh Gupta]

Does clicking on the link causing the page to postback.

Are you setting the NavigateURL property in onRowDataBound event? I guess, you are not. I think you are setting this property in Page Load event wrapped inside IsPostBack check.

I might be wrong though!!!

[MMock]

You are right: I am not setting it in RowDataBound.

You are wrong: I am not setting it in PageLoad.

I hope you are not sorry you asked: I have filters on my page where the user can say what kind of records he wants to see in the grid. So let's say he says he wants to see all records with a customer name like "truck". He fills that info out then hits a submit button. Here's my code from then on:

    Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

        PopulateGrid()

    End Sub

    Sub PopulateGrid()

        Dim ds As New DataSet

        GetDataForGrid(ds)   ' Gets data according to filters user selected

        Me.GridView1.DataSource = ds

        Try
            Me.GridView1.DataBind()


            ' Row-by-row of the grid, process each column...
            Dim idxData As Integer
            Dim idxGrid As Integer = 0
            For idxData = Me.GridView1.PageSize * Me.GridView1.PageIndex _
              To Me.GridView1.PageSize * (Me.GridView1.PageIndex + 1) - 1

                Dim hyEstTotal As HyperLink = DirectCast(Me.GridView1.Rows(idxGrid).FindControl("hyEstTotal"), HyperLink)

                hyEstTotal.NavigateUrl = _
                    "javascript:window.open('show_details.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');"

                If idxData >= (ds.Tables(0).Rows.Count - 1) Then Exit For

                idxGrid += 1

            Next

Do you see something that's incorrect?

[mendhak]

hyEstTotal.Attributes.Add("onclick", _
                    "javascript:window.open('show_details.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');return false;")
 
hyEstTotal.NavigateUrl = "javascript:void;"
'Or
'hyEstTotal.NavigateUrl = "show_details.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik"))

[mendhak]

The reason you get the [object] displayed is when you click on the link, the page is attempting to 'go to' what the href is telling it to go to. The href is calling some javascript. window.open() returns a value that is a javascript "object". Browser sees that and displays it.

[MMock]

Thank you. [object] has gone away! But, I *still* don't have scrollbars. I really want these scrollbars, otherwise I wouldn't be such a pain!

[MMock]

I know computers can be flaky, but can you get anymore clear than this: scrollbars=1!!!!

[mendhak]

The only assumption I can make is that this has something to do with browser settings. Try this in another browser. Try setting a smaller height and width. Try a temporary URL like vbforums.com or mendhak.com

[MMock]

Thanks for the suggestions. I was also thinking of trying the same code with another of my pages that I want to open in the same manner. Will let you know how it turns out...

[MMock]

No matter what I do, I can't scroll.

The only one of mendhak's suggestions I couldn't try, was to code a url such as www.vbforums.com in my link because my code looked for it inside its own folder structure. None of the other suggestion revealed anything (Firefox, surprisingly, was worse and even the parts of the non-scrollable window that worked in IE7 didn't work in Firefox).

This page is in production so I really need it to scroll. I don't know what else to try.

Help, please. I'm so stuck.

[MMock]

IE6 won't work either. At least it's a consistent problem.

My coworker just offered me some nuts from his bag of almonds. I said I needed a bag of scrollbars...

Anyone got any???

I guess I should post my lastest and not-so-greatest code:

                Dim hyEstTotal As HyperLink = DirectCast(Me.gvUploadRateReady.Rows(idxGrid).FindControl("hyEstTotal"), HyperLink)
                'hyEstTotal.Attributes.Add("onclick", _
                '  "javascript:window.open(ThisPageWontScroll.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'scrollbars=1');")
                hyEstTotal.Attributes.Add("onclick", _
                  "javascript:window.open(ThisPageWontScroll.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');return false;")
                'hyEstTotal.Attributes.Add("onclick", _
                '  "javascript:window.open('www.vbforums.com', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');return false;")
                hyEstTotal.NavigateUrl = "javascript:void;"

[MMock]

The only one of mendhak's suggestions I couldn't try, was to code a url such as www.vbforums.com in my link

I needed http:// in front, oops.

Eureka! vbforums opens with scroll bars! So it must be in my page, not how I am opening it??? Thanks for the trouble-shooting tip, mendhak!

[MMock]

I substituted the old asp page for my new aspx page and it is opening with scrollbars. I am certain now it is in the page I am going to...I just have to find out why.

[mendhak]

When you do your window.open, you're not giving a single quote to the page name.

Dim hyl As New HyperLink()
            hyl = CType(e.Row.FindControl("hyl"), HyperLink)
            hyl.Attributes.Add("onclick", _
                  "window.open('http://www.mendhak.com/', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');return false;")
            hyl.NavigateUrl = "#"
            hyl.Text = "lol"

[MMock]

Do I really have to put everything in a panel?

[MMock]

When you do your window.open, you're not giving a single quote to the page name.

I'm sorry - I think we cross-posted there. To which of my rapid-fire-in-succession posts was this an answer???

[mendhak]

I answered #17. I tried my code out and it worked - I got a popup window and the scrollbar, etc.

What I noticed missing for you was that single quote.

[MMock]

In an effort to protect my company's secrets I edited the instruction and I think I deleted the single quote and misled you. So this is the truth, the whole truth, blah blah blah:

                hyEstTotal.Attributes.Add("onclick", _
                  "javascript:window.open('show_inv_details_estimate.asp?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600');return false;")
                'hyEstTotal.Attributes.Add("onclick", _
                '  "javascript:window.open('show_inv_details_estimate.aspx?inv_hdr_ik=" + CStr(ds.Tables(0).Rows(idxData).Item("inv_hdr_ik")) + "', 'DETAILS', 'scrollbars,menubar,resizable,width=800,height=600');return false;")

I promise you, the first one has scroll bars. When I comment out the first way and try the second, there are no scroll bars. It must be show_inv_details_estimate.aspx. It is full of gridviews and they are off the bottom of the page. Do I have to put them all in a panel?

Thanks, and I apologize for my mistake.

[mendhak]

The first one has

'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=1,resizable=1,location=0,width=800,height=600 '

The second one has

'scrollbars,menubar,resizable,width=800,height=600'



Did that make a difference?

[MMock]

When I was googling, I saw sample code that instead of saying =1 or =0 just said the name of what they wanted and if it was zero left the name off, know what I mean? So to get scrollbars it was just "scrollbars" and if they didn't want scrollbars they just left that keyword out. It was something I tried that made no difference.

Are you making whatever attempt you can on my behalf so I don't have to redesign the page with a panel? Or you don't think panels are what I need?

Thanks.

[mendhak]

Alright, so you get a popup... and for the ASPX version it won't show a scrollbar.

First question - when you view that ASPX normally, in a normal tab (not a popup, does it show the scrollbars?

Second, what does the markup look like on this offending page?

Not sure what you mean by panels here but you should be able to get this sorted by modifying the markup in the offending page to allow for scrollbars.

[MMock]

I've *never* seen scrollbars on this page.

Markup (hope you're not sorry you asked...it's long, hence the need for scrollbars!): Oops - it made my post exceed the mask. I've attached it.

Regarding panels...when I googled asp.net and scrollbars, the first few hits all said something about putting your controls on a panel and scrolling the panel.

Thanks.

[mendhak]

Took me 0.5 seconds to find it.

html {
overflow: hidden;
}

That means that if there's an overflow, don't show it. Keep it hidden from the user.

[MMock]

Took me 0.5 seconds to find it.

If I were you, I wouldn't have posted until Monday and told me you worked on it all weekend long! You could've given me an asp file back and told me to replace mine, and I don't think I ever would've noticed the one-line change! But I wouldn't have learned anything either.

If I weren't so happy I'd feel very stupid. Thanks. My appreciation is in no way proportionate to how long it took you to find it (well, I'm not forgetting there were like 28 posts in this thread that you read through!)

[mendhak]

Hehe... and to think that all the previous discussion was moot, due to this one tiny CSS setting.
