On button long press (like press start button & hold for 2 sec) only start call a method Start().

my shortest solution for this problem:

private bool mouseUp = false;
private const int holdButtonDuration = 2000; //milliseconds
private void btnTest_MouseDown(object sender, MouseEventArgs e)
{
mouseUp = false;
Stopwatch sw = new Stopwatch();
sw.Start();
while (e.Button == MouseButtons.Left && e.Clicks == 1 && (mouseUp == false && sw.ElapsedMilliseconds < holdButtonDuration))
Application.DoEvents();
if (sw.ElapsedMilliseconds < holdButtonDuration)
btnTest_ShortClick(sender, e);
else
btnTest_LongClick(sender, e);
}
private void btnTest_MouseUp(object sender, MouseEventArgs e)
{
mouseUp = true;
}
