WebFormPostBackOptions is not defined error on buttun click

Hi,

Everything i my project was working fine untill i implemented url rewrite(using global.asax file)

Now i am getting problems(ajax not working and some buttuns not clicking)

on clicking buttub i found this error in console

"WebForm_PostBackOptions is not defined"

This error is mainly due to rewrite of Webresource.axd.

How to resolve this error.

Thanks in advance.
