you can use event that, like:

datagridview.cellvaluechanged event

or use datagridview.cellformatting event this:

private void datagridview1_cellformatting(object sender,     datagridviewcellformattingeventargs e) {     datagridview dgv = (datagridview)sender;     if (dgv.columns[e.columnindex].name == "i" &&         e.rowindex >= 0 &&         dgv["i", e.rowindex].value int) &&         (((int)dgv["i", e.rowindex].value) == 0)         {            e.value = "-";            e.formattingapplied = true;                    }     }     else if (dgv.columns[e.columnindex].name == "b" &&         e.rowindex >= 0 &&         dgv["b", e.rowindex].value int) &&         (((int)dgv["b", e.rowindex].value) == 1000)         {            e.value = "good";            e.formattingapplied = true;                    }     } }
