Can't fire event Key_Down c#

I using form event Form1_KeyDown to move panelcontrol4

Private void Form1_KeyDown(object sender, KeyEventArgs e)
{
     if (e.KeyCode == Keys.Left)
     {
        panelControl4.Location = new Point(panelControl4.Location.X-1,panelControl4.Location.Y);
     }
}

If Form1 have 1 control panelcontrol4 event worked but i add 1 control eg : simplebutton1 ... then can't fire Form1_KeyDown . Then i must enable = false simplebutton1 , then Form1_KeyDown work

Thanks you for help

In General The _KeyDown will Occurs when a key is pressed while the control has focus. In your case the Form1 doesn't have Focus at the Time of key press occurs.

Controls on your form might automatically handle the keydown event and your code won't get called. See Control.KeyDown Event.
