ASP.NET Ajax 1.0 error Sys.WebForms.PageRequestManagerParserErrorException
If you’ve seen this error, you’ve probably already spent some time trying to resolve it. We only encountered this error on our test server and it turned out the missing piece was a web.config setting. Also the following piece of code at the top of a page seems to alleviate some AJAX refresh bugs.
1) Make sure this in is your web.config
<httpModules>
<add name=”ScriptModule” type=”System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″/>
</httpModules>
2) Add this to the to the Page declaration if you’re experiencing some page refresh bugs
enableEventValidation=”false”

Example of one of my pages (you can locate this on top of every page, ‘CCMAN_Tree’ is my page name you should have a different name):
After adding EnablePartialRendering=â€false†to all my web pages, my problem was solved. Very nice TIP, thanks a lot.
