vb .net (asp .net) app... response.write

**pgrimes** · Aug 7th, 2002, 11:07 AM

I feel this falls into the 'stupid question' category, but the time has come that I must ask it.

I have this code from my vb .net (asp .net) application (created in visual studio .net)

VB Code:

Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
    End Sub
 
#End Region
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Response.Write("<table><tr><td>Why does this show up above the html tags</td></tr></table>")
    End Sub
 
End Class

Why does my response.write show get written above every other tag on the page... like this:
[Results]

Code:

<table><tr><td>Why does this show up above the other tags?</td></tr></table>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
	<HEAD>
		<title>WebForm1</title>
		<meta name="GENERATOR" content="Microsoft Visual Studio.NET 7.0">
		<meta name="CODE_LANGUAGE" content="Visual Basic 7.0">
		<meta name="vs_defaultClientScript" content="JavaScript">
		<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
	</HEAD>
	<body MS_POSITIONING="GridLayout">
		<form name="Form1" method="post" action="WebForm1.aspx" id="Form1">
<input type="hidden" name="__VIEWSTATE" value="dDwtMTI3OTMzNDM4NDs7PuIeAj03w2/SZE+efTMFhqIXJ3Ap" />

		</form>
	</body>
</HTML>

How do I make the stuff from my response.write get written inside of the <body> tags on the resulting page????

My guess is that I need to stick some 'runat=server' stuff somewhere, but I don't know where.

thanks!

use placeholder control then you can set its value in page load

stick this where you need it

<asp:PlaceHolder id="myPlace" runat="server"/>

in page load, just say

myPlace.Text = "<table><tr><td>Why does this show up above the html tags</td></tr></table>"

aha. Sounds good... now for the massive restructuring on all of my projects

*doh*

thanks again.

your welcome.

ASP .NET can be a bit tricky a times with knowing what controls to use to avoid using inline asp tags <% %>

**pgrimes** · Aug 7th, 2002, 11:30 AM

hmm... where do I put this:
<asp:PlaceHolder id="myPlace" runat="server"/>
in the aspx.vb code?

Just to be clear, the code that I posted second in my original post (labeled "results") is what I get when I 'view source' after the WebForm1.aspx is run.

**Cander** · Aug 7th, 2002, 11:33 AM

you put it where the html should appear.

**pgrimes** · Aug 7th, 2002, 11:38 AM

Sorry, I'm not gettin' it.

Here's my aspx.vb code again:

VB Code:

Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
 
    End Sub
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
<asp:PlaceHolder id="myPlace" runat="server"/>
    End Sub
 
#End Region
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        myPlace.Text = "<table><tr><td>Why does this show up above the html tags</td></tr></table>"
 
    End Sub
 
End Class

Everywhere I put '<asp:PlaceHolder id="myPlace" runat="server"/>' in that code, it has problems with it. I'm confused I guess.

**Cander** · Aug 7th, 2002, 11:40 AM

no you dont stick it in subs, you put it in the actual html code area

for example

<html>
<body>
<asp:PlaceHolder blah blah blah..../>
</body>
</html>

This is called a web form control. You may want to read up on them as they are VERY helpful and powerful.

I think the problem is the load is the first thign run. How to fix i am nto sure, haven't looked into it yet.

did youcreate the page load event? You shoudl move that code to another place, out side of the load.

I will experiment when ido a fresh xp/.net install and let you knwo my results

Oh... I just noticed something that I haven't seen before. I've always double clicked the webform when it shows up in vs .net. I just right clicked on the webform and clicked on 'View HTML Source'.

Now I see where I need to put '<asp:PlaceHolder id="myPlace" runat="server"/>'.

I didn't know that I had access to the html source of the webform.aspx. Until just now, I had only seen it by clicking view source in ie after the aspx was run.

Thanks a ton for all of your quick replies!

**Cander** · Aug 7th, 2002, 11:49 AM

you welcome, and just so you dont get confused, after putting in that <asp;PlaceHolder, if you then view the requested pages source, you will not see that <asp:Placeholder. it will be replaced with the html you set as the .Text property.

Just some FYI to help you better understand how Web Form controls work.

right right

kewl kewl

k... one more question. In the html portion of WebForm1.aspx, I have this:

Code:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="example1.WebForm1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
	<HEAD>
		<title>WebForm1</title>
		<meta name="GENERATOR" content="Microsoft Visual Studio.NET 7.0">
		<meta name="CODE_LANGUAGE" content="Visual Basic 7.0">
		<meta name="vs_defaultClientScript" content="JavaScript">
		<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
	</HEAD>
	<body MS_POSITIONING="GridLayout">
		<form id="Form1" method="post" runat="server">
	<asp:PlaceHolder id="myPlace" runat="server"/>
		</form>
	</body>
</HTML>

In WebForm1.aspx.vb, I have this:

VB Code:

Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
 
    End Sub
 
#End Region
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        'Says "Name 'myPlace' is not decalred.
        myPlace.Text = "<table><tr><td>Why does this show up above the html tags</td></tr></table>"
 
    End Sub
 
End Class

It says that myPlace is not declared. Should this be happening? What do I declare it as?

**Cander** · Aug 7th, 2002, 12:17 PM

oh you are using codebehind..

right below this line
Inherits System.Web.UI.Page

put

Public myPlace As System.Web.UI.WebControls.PlaceHolder

**pgrimes** · Aug 7th, 2002, 12:32 PM

hmm... two problems now...
one is here:
Public myPlace As System.Web.UI.WebControls.PlaceHolder

myPlace is underlined, and gives error:

'myPlace' is already declared as 'Protected Dim WithEvents myPlace As System.Web.UI.WebControls.PlaceHolder' in this class

The other is here:
myPlace.Text
that ^ is underlined and gives error:

'Text' is not a member of 'System.Web.UI.WebControls.PlaceHolder'

**Cander** · Aug 7th, 2002, 12:40 PM

oopss..i fudges up..I gave you the wrong control name..change PlaceHolder to Literal...

That should do it..I hope.

**pgrimes** · Aug 7th, 2002, 12:49 PM

TADDAAA....

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
	<HEAD>
		<title>WebForm1</title>
		<meta name="GENERATOR" content="Microsoft Visual Studio.NET 7.0">

		<meta name="vs_defaultClientScript" content="JavaScript">
		<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
	</HEAD>
	<body MS_POSITIONING="GridLayout">
		<form name="Form1" method="post" action="WebForm1.aspx" id="Form1">
<input type="hidden" name="__VIEWSTATE" value="dDwtMjM2MzU3MjA2O3Q8O2w8aTwxPjs+O2w8dDw7bDxpPDE+Oz47bDx0PHA8bDxUZXh0Oz47bDxcPHRhYmxlXD5cPHRyXD5cPHRkXD5XaHkgZG9lcyB0aGlzIHNob3cgdXAgYWJvdmUgdGhlIGh0bWwgdGFnc1w8L3RkXD5cPC90clw+XDwvdGFibGVcPjs+Pjs7Pjs+Pjs+Pjs+BONwb6kb293q1honbKd2Srrv0bQ=" />

			<table><tr><td>Why does this show up above the html tags</td></tr></table>
		</form>
	</body>
</HTML>

Thanks a ton man

. That seems to have done the trick.
