(just imagine this grid has vertical lines which makes cells for each
entry)

if user selects any cell then I want to change the cell's background
color

How to design a grid to show the matrix values [like the above] also I
don't know which control will be helpful [datagrid, listview..etc] ?
can my requirements [like changing each cell value] be achievable ?

Thanks
