Hi,

I am using a Radtabstrip with 2 tabs in which I am showing 2 user control and both are having Radgrid and I am trying to add ajax manger to it. One of my user control is already having RadAjaxManagerProxy. When I click on tabs, the user control without ajax manger is coming but the one with ajax manager doesn't come up.
Is this because the grid is having multiple ajax manager?

Hello Lubna,

Please review these online resources on how to load user controls dynamically with ajax and check if you have followed the instructions there.
http://demos.telerik.com/aspnet-ajax/ajax/examples/common/loadingusercontrols/defaultcs.aspx

Let me know how it goes.
