I need catch the event endresize in WPF.
See Question&Answers more detail:osWPF doesn't provide an event that solely fires at the end of the resize process. SizeChanged is the only event associated with Window resizing - and it will fire multiple times during the resizing process.
A total hack would be to constantly set a timer ticking when the SizeChanged event fires. Then timer will not get a chance to tick until resizing ends and at that point do your one time processing.
public MyUserControl()
{
_resizeTimer.Tick += _resizeTimer_Tick;
}
DispatcherTimer _resizeTimer = new DispatcherTimer { Interval = new TimeSpan(0, 0, 0, 0, 1500), IsEnabled = false };
private void UserControl_SizeChanged(object sender, SizeChangedEventArgs e)
{
_resizeTimer.IsEnabled = true;
_resizeTimer.Stop();
_resizeTimer.Start();
}
void _resizeTimer_Tick(object sender, EventArgs e)
{
_resizeTimer.IsEnabled = false;
//Do end of resize processing
}
