Hi,

You can do it in different ways. But I think best will be to override
the Select method. Keet track of last selected row in a property. In
the overridden Select first unselect the last selected row and select
the currentrowindex.
The code will be like this...

public new void Select(int vintRowToSelect)
{
    if(intCurrentDataGridRowIndex > -1)
    {
        base.UnSelect(intCurrentDataGridRowIndex);
    }
    base.Select(vintRowToSelect);
}

I hope this helps

Cheers
Raj
