a possible solution: Disable output caching for pages. I had output caching enabled for .ASCX files. That causes the problem.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near '

<!DOCTYPE html PUB'.

Hi,

The solution mentioned above didn't work for me. I tried EnablePartialRendering="false" in scriptmanager, and this worked for me

make sure trace is set to false in ur page
also include all your controls inside the update panel
also use Response.redirect instead of server.transfer
also try to put
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn_Update" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="btn_Update" EventName="Click" />

</Triggers>

at the begining

<asp:AsyncPostBackTrigger ControlID="btn_Update" EventName="Click" />

to

<asp:PostBackTrigger ControlID="btn_Update" EventName="Click" />

Check the session timeout property in the web.config.

Make sure that you are not nullifying(Remove/Abondon) the session key in 10-15 minutes in case if you are using Session in your page.

also remove the 3600 from ur script manger

also

My only idea would to be change your button field to a hyperlink, and if you're currently passing a command argument, pass it in the querystring.
