                    </DataGrid.Columns>

Answer 1

As an example you could do something like this..

row.Cells[2].ButtonName.Style.BackColor = System.Drawing.Color.Red;

This is pseudo-code but you would have to know the actual cell based on the index this should be enough to get you started could you also post the code behind of the event you are trying to code the button change in..? thanks
