Wait one second in running program

Question

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

İ want to wait one second before

Answer 1

Try this function

public void Wait(int time) 
{           
    Thread thread = new Thread(delegate()
    {   
        System.Threading.Thread.Sleep(time);
    });
    thread.Start();
    while (thread.IsAlive)
    Application.DoEvents();
}

Call function

Wait(1000); // Wait for 1000ms = 1s

Answer 2

Personally I think Thread.Sleep is a poor implementation. It locks the UI etc. I personally like timer implementations since it waits then fires.

Usage: DelayFactory.DelayAction(500, new Action(() => { this.RunAction(); }));

//Note Forms.Timer and Timer() have similar implementations. 

public static void DelayAction(int millisecond, Action action)
{
    var timer = new DispatcherTimer();
    timer.Tick += delegate

    {
        action.Invoke();
        timer.Stop();
    };

    timer.Interval = TimeSpan.FromMilliseconds(millisecond);
    timer.Start();
}

Answer 3

use dataGridView1.Refresh(); :)

Answer 4

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);
