Symptoms

When the following conditions exist, you may receive a client-side script error in Netscape or in Microsoft Internet Explorer:
  1. You add the folowing form to a user control: 
    <form id="Form1"
		  name="Form1" runat="server">
  2. You add the user control, for example, Workspace1, to a page.
An auto-generated script similar to the following script is added to the page:
<form name="Workspace1:Form1"
		  method="post" action="formtest2.aspx" id="Workspace1_Form1">

The script error occurs because the form name and the form ID are different, and because the form name contains a colon.

Another example of the problem in the auto-generated script for a __doPostBack function follows:
function
		  __doPostBack(eventTarget, eventArgument) { 
 var theform; 
if
		  (window.navigator.appName.toLowerCase().indexOf("netscape") > -1) { 

		  theform = document.forms["_ctl14:Form1"]; 
} 
else { 
 theform =
		  document._ctl14:Form1; 
} 
theform.__EVENTTARGET.value =
		  eventTarget.split("$").join(":"); 
theform.__EVENTARGUMENT.value =
		  eventArgument; 
theform.submit();
}

Notice that the Form has a uniqueID property that contains a colon in the following lines: 
theform =
		  document.forms["_ctl14:Form1"]; 
 theform = document._ctl14:Form1;
ASP.NET replaces the colon with an underscore ( _ ) character to address the problem.
