Button Click Event WebPart Button Sys.Webforms.PageRequestManagerServerErrorException:

Hi,

I have a SharePoint 2010 visual WebPart, which has ASP.NET Multiview control. When deployed, this control works fine on my local server and it even works fine in the Development server; however, when deployed on to the production server, it stops working.

I am not able to change Views on the production server, when I try to debug the WebPart in IE Developer Tool (Using IE 11), I get this error that says “Sys.WebForms.PageRequestManagerServerErrorException: An unexpected error has occurred.” in the ScriptResource.axd file.

Even the Button click is not working, getting the same error in the Button Click.

Can someone help me with this?

Regards, Vikram
