System.Threading.Thread.Sleep(1000);

? want to wait one second before printing my grid cells with this code, but it isn't working. What can i do?

Answer 1

Is it pausing, but you don't see your red color appear in the cell? Try this:

dataGridView1.Rows[x1].Cells[y1].Style.BackColor = System.Drawing.Color.Red;
dataGridView1.Refresh();
System.Threading.Thread.Sleep(1000);
