The RadGrid.SelectedItems collection stores the indexes of the selected items in the order they are selected. To demonstrate, please follow these steps:
1. Set EnablePostBackOnRowClick="true" in the ClientSettings of RadGrid
2. Subscribe to the ItemCommand event
3. Place the following code in the ItemCommand event handler:
|if (e.CommandName == "RowClick")
| for(int i=0; i<RadGrid1.SelectedItems.Count; i++)
When you click on a row and the page makes a postback, you will see the indexes of the selected items enumerated in the order they are selected.
