I just don't know what is the difference between timer and a regular loop in this case.

could you tell me how to use it?

I use the following code but it didn't work.

DateTime start = DateTime.Now;
dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Black;
TimeSpan interval = DateTime.Now - start;
while (interval.TotalSeconds<5)
{
interval = DateTime.Now - start;
}
dataGridView1.Rows[0].DefaultCellStyle.BackColor = Color.Yellow;
