I am capturing the key down event and checking for ctrl+v and handling custom behaviour

I need to be able to paste a cell to a range -- like copy one value and be able to paste it over a selected cell range. So if someone selected a cell with some value X, copied it and then selected a random range of cells and tried to paste , all the cells in the range would get it -- like EXCEL.

Has anyone done this before? Infragistics support -- is there a good way to do this?

Please advise.

Thanks,
