Everything thing related to the RADGrid is working fine, but RADTabStrip is not working as expected, when I select "Contact Information" which is 2nd tab page inside the RADTabStrip it is not actually selecting it and so the content of the 2nd Page "PageView 2" is also not showing.

what i am missing here? do i have to configure something in the update panel for RadTabStrip?

kindly write the code as i am new to Rad World.

Thanks, I resolved it.

[Vipul]

how did you resolve it? i have same issue.

[Vipul]

i missed the MultiPageID="AssessorMultiPage" binding , adding this resolved the issue.
