datagridview cellformatting event

Question

5.00/5 (1 vote)

See more:

During the population of the datagridview dgv column TCharge is formatted to 2 decimal places using the following code:

C#

dgv.Columns["TCharge"].DefaultCellStyle.Format = "N2";

Now, I want the values in column CValue to be formatted based on the true/false flag in column TCash. So I have placed a code in the cellformatting event. Is this ok, please? I ask because the program seems to go into a loop forever...

Thanks

C#

private void dgv_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (dgv.Columns[e.ColumnIndex].Name.ToLower() == "cvalue")
            {
                if (e.Value != null)
                {
                    if (bool.Parse(dgv["TCash", e.RowIndex].Value.ToString()) == true)
                    {
                        dgv.Columns["CValue"].DefaultCellStyle.Format = "N2";
                    }
                    else
                    {
                        dgv.Columns["CValue"].DefaultCellStyle.Format = "N1";
                    }
                }
            }
        }

Solution 1

I would just change the style for the cell rather than the entire column.

C#

if (bool.Parse(dgv["TCash", e.RowIndex].Value.ToString()) == true)
{
    e.CellStyle.Format = "N2";
}
else
{
    e.CellStyle.Format = "N1";
}
