Retrieve SelectedItems from a RadGrid

I have a RadGrid from Telerik with a GridClientSelectColumn column. When the user 开发者_Python百科checks records and clicks the action button the SelectedItems is empty.

Is there any way to retrieve SelectedItems?

The selected items should be there unless you call Rebind() for the grid explicitly from outer control. Tested on modified version of this sample, worked with no issues.
