I have a form which is showing the error as Error : Expected ';' at  the javascript autogenerated by ASP.NET
here is the autogenerated code for your info
====================================
<form name="_ctl0:Default" method="post" action="MyForm.aspx" id="_ctl0_Default">
<input type="hidden" name="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" value="dDw1MDcyNzUzNTY7dDw7bDxpPDI" />

<script language="javascript">
<!--
      function __doPostBack(eventTarget, eventArgument) {
            var theform;
            if (window.navigator.appName.toLowerCase().indexOf("netscape") > -1) {
                  theform = document.forms["_ctl0:Default"];
            }
            else {
                  theform = document._ctl0:Default;
            }
            theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
            theform.__EVENTARGUMENT.value = eventArgument;
            theform.submit();
      }
// -->
</script>
==============================

now the error is showing at the : (colon)
             else {
      theform = document._ctl0:Default;

OS : Windows 2003 Server Standard,

i think that the problem can invoke by the name of the form
can you post the <form> tag

if the id of the form tag is Default it can cause such a problem
if i'm write change the id of the form tag with no usual value

Hi, try removing all : characters. Also in your form name. Afaik javascript doesn't like colons.

That code was autogenerated by ASP.NET, nothing was done by me..

Commented:
yes,

but it's base on the
<form id="Default" method="post" runat="server"> which is again autogenerated from the vs in your html code of the .aspx

so you have to change the id from Default to something else because Default is reserved
