Hi,

I want a RadGrid with expand/collapse functionallity.
When expanding a selected row, I want to display another RadGrid with the same functionallity, but I want to display image or some data (not a table or grid).

I read about hirarchical grids, and I need something like a grid with detailtable that has nestedview template.
Is it possible to do something like this?
Is there an implementation for expand/collapse in DetailTable?
How can I call itemcreated function for the DetailTable?

Is there any example for something like this?

Thanks!
