When the ItemsSource is not set: ArgumentOutOfRangeException is thrown
When the ItemsSource is set to an empty collection: DivideByZeroException is thrown
When creating a new item in the GridView by either mouse or insert button the row is not selected or highlighted.
I guess this is a bug, since a cell in the new row has focus but not the row.
When adding a new row and we click inside a DropDownContent of a DropDown control, the RadGridView loses focus. This way RowValidating event is called which is not expected.
Bind a grid to a DataView
Start editing and change the values of a few cells.
Press Escape twice to cancel the edit of the entire row.
Expected: the values return to the old values
Actual: the values remain the last entered ones
