Asp.net GridView export to excel issue

Question

I'm trying to export my GridView to excel, but I'm having some problems.

At first I got few other errors so I added EnableEventValidation ="false" to my page, and I added public override void VerifyRenderingInServerForm(Control control) in my source code. Now i'm getting this error from javascript:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

I'm guessing it's because my grid is in ajax update panel, but i'm not sure about it.

Any idea?

Thanks.

it sounds like you got a server side exception and you also told the script manager to handle the error. make sure you don't have any response.write or response.redirect since they don't work well with update panel. — Ray Cheng

This is because of your update panel if you remove your update panel it will work or you can set a PostBackTrigger for detail see this blog post
