I'd like to invoke an event from unknown control in code. I'd love to do the following, but the "KeyDown" property is only for adding or removing (+= -=) events, not for invoking...
private void QBDT_KeyDown(object sender, KeyEventArgs e)
{
    Control l_oActiveControl = this.ActiveControl;
    if (l_oActiveControl is TextBox)
    {
        TextBox l_tbActive = l_oActiveControl as TextBox;
        if (e.KeyCode == Keys.C || e.KeyCode == Keys.Z || e.KeyCode == Keys.X || e.KeyCode == Keys.A)
        {
            l_oActiveControl.KeyDown(sender, e); 
            return;
        }
    }
    //Do Something
}
Any ideas? Thanks :)
