Rows not de-selecting

[Nordy]

I'm using the following code to select rows in a control that I've derived from the RadGridView control that has already been populated with data:

public void SelectRows(DataTable tbl)
{
   foreach (DataRow row in tbl.Rows)
      this.Rows[_KeyMappings[Convert.ToInt32(row[_KeyMember])]].IsSelected = true;
   if (tbl.Rows.Count > 0)
      this.CurrentRow = this.SelectedRows[0];
   this.Update();
}

_KeyMappings is a Dictionary<int, int> that maps primary key values to row indecies, and _KeyMember defines what the primary key is.  This works great, until the user tries to click on a row.  I'd LIKE the selected rows to clear out (since the user just picked a new one), as the code above is simply for setting the start up state of the control from data, but they don't.  When the user clicks a new row, any previously selected rows should become unselected.

Scratch that.  Apparently, it was because the SelectionMode property was set to CellSelect.
