How to disable dragselection in Infragistics UltraGrid

Question

I use Infragistics UltraGrid and I'm trying to disable drag selection. I have to limit selecting multiple rows only by holding down shift or control key.

In my InitializeComponent() function I'm setting ultragrid like this:

ultragrid.DisplayLayout.Override.SelectTypeCell = SelectType.ExtendedAutoDrag
ultragrid.DisplayLayout.Override.CellClickAction = CellClickAction.RowSelect

You can disable any selection in UltraGrid when shift or control keys are not pressed by canceling BeforeSelectChange event in this scenarios.

private void UltraGrid1_BeforeSelectChange(object sender, BeforeSelectChangeEventArgs e)
{           
    if (Control.ModifierKeys != Keys.Shift && Control.ModifierKeys != Keys.Control)
    {
        e.Cancel = true;
    }
}
