Hello,
KoolGrid already has the AllowMultiSelecting property which enable selecting more than one row.
How about enable RangeSelecting to enable the range selection when user presses the <Shift> keyboard button or the combination of <Ctrl> +<Shift> keyboard buttons to add non contiguos ranges?
I think, IMHO, that it will be a very good feature.
Best regards.
