Dynamically loading user control

D

Divya

Hi

I am adding a user control to an aspx page dynamically. This user control has a link button. Hence I have to enclose it in a form tag with runat=server. When I execute the page, I get a javascript runtime error (; expected). The error occurs in the asp generated part of the code. The line where this error occurs is
else {theform = document._ctl0:form1;} in the following part of code

<html><head><meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1"><meta name="CODE_LANGUAGE" Content="C#"><meta name="vs_defaultClientScript" content="JavaScript"><meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"><title>NMG Digital Marketing System</title><link href= ..\code\css\default.css rel='stylesheet' type='text/css'></head><body><table border="1" width="100%" height="100%"><tr><td align="center" height="20"><h3>NMG Digital Marketing System</h3></td></tr><tr><td align="center" valign="top"><form id="mainForm" runat="server" method=post><script language="javascript"

I am loading the static HTML part of the above page from a template file and I am dynamically loading the user control (manageadmin.ascx)
How do I solve this problem? Could someone please help

Thanks

This is a known problem in ASP.NET 1.1. There is a patch, but I'm afraid
I've misplaced the number of the KB article.

Hi John,

Thanks for the tip. I looked up the KB article and contacted Microsoft

about this, got the fix, installed it and it executed fine. But now, I seem
to have another problem. I am guessing that it is due to the patch (for
..Net) that I installed. I have an aspx page dynamically loading a user
control. The user control has a datagrid with a column of 'edit' link
buttons. When the user clicks on one of the edit buttons, I want to redirect
to another aspx page with the itemIndex of the row (that was clicked), sent
as a query string.
When I execute this and click an edit button link in the datagrid, it

throws a javascript runtime error -
'__EVENTTARGET' is null or not an object.
In the source, it points to the line -
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");

Divya, I didn't see this problem after applying the patch. However:
....
Below is the entire source (generated by .Net) of the page when the error occurs -

I notice that you have a form called "mainForm". You should find a way to do
without it. There should only be one form on the page, as far as ASP.NET is
concerned. At the very least you should check to see if the same problem
happens on a page without the nested forms.
