Hi naimish,

Can you try debugging the page and see if the Selecting event is fired when you page the inner grid? Also check if placing the ObjectDataSource declaration above this of RadGrid2 makes any difference?

Hi,
Whenever i try to select page size from dropdown, the on selecting method gets call, but this time, the item data bound of main radgrid
does not get called, where iam setting input parameter to the radlistview.

Due to that in this time the input parameter gets empty.
Am i doing something wrong, i enabled inbuilt paging by doing allow paging true for nested radlistview not made any custom paging, than why it is happening.

Hi naimish,

Can you send a sample page code, using dummy data for instance, which I could run locally and see what happens there?
