Dear Mentors,

I am trying using Ajax Update Panel to update my gridview without using postback.
But surprised to see that its not working with

xhtmlConformance mode="Legacy" in web.config. So i commented this tag in Web.config
but after that my CSS for the GridView is not working.

Can you please suggest me solution.

Hello mentors,

Please suggest.Is there any way to set xhtmlConformance ="Transitional"
for a particular page while keeping xhtmlConformance ="Legacy" for the whole site???

The issue is because my project is a vs2003 to vs2010 converted project.

When i use xhtmlConformance ="Legacy" the postback of update panel no longer work as asynchronous postback as the scriptmanager.IsInAsyncPostBack comes out false for every __dopostback on update panel while the same comes out true if i dont use "Legacy"

Help please.
