Hi,

Please make sure that you are accessing master page variable like below:

- Ctype(master.findcontrol("label"),label).text ="Test"
- Ctype(master.findcontrol("updatepanelID"),updatepanel).update

Please double check whether you have added ScriptManager on your page or not. In your situation, we suggest that you'd better remove the contents inside the ContentTemplate and the associated code on code behind, then have a test. If it doesn't work, you shall check your system environments.

This is a generic error message. To see a helpful error add EnablePartialRendering="true" to your update panel tag, and set customErrors="Off" in your web.config. Then you should see a detailed description of what's wrong.

The exception can be also in the aspx markup (in <%= , or in <%# code blocks). This is easily be detected for the first request (you get the general exception page), but for partial postbacks this is harder.If you put a break point in code-behind, and use F10/F11, the debugger will step in also in the aspx markup.For example, just put a break-point in a late event like OnPreRender (if you not have this event, just create it), when the break-point triggered press F11 until you reach the aspx/ascx markup.

This error occures in below scenarios:

1. The page that you want to submit is a main page and through AJAX you got some
content from another page but with the returned content. It's contained a
variable name say "__VIEWSTATE". It will replaced the same variable of the main
page.when you try to submit the content of main page. The error you mentioned
will comes. Because the content of __VIEWSTATE of main page is replaced
already.

There are two solutions for this:
The first is to chagne the Ajax page to HTML form and HTML controls.
Another solutions is to move all the elements from Ajax page to main page.

2. Browsers that cannot support hidden fields very well - http://support.microsoft.com/kb/831150
3. Small numbers - http://support.microsoft.com/kb/812399
4. Your viewstate is too big. Some browsers can't handle that
5. There is some network error. The viewstate information was corrupted on the way, but I doubt it in your case cos problem only exists with Opera
6. If hosted on a web farm http://support.microsoft.com/default.aspx?scid=kb;EN-US;323744
Also have a look at this, u may find some info in there to help you

CAUSE

loadTOCNode(1, 'cause');

This problem occurs because the .NET Framework converts small numbers in the View State to Scientific Notation. When the .NET Framework tries to deserialize the number, it cannot recognize the number or the number is not the expected data format.
