using a WPF custom control in Winforms RRS feed

  • Question

  • I am making a wpf custom control in Winforms. I am using an element host to  embedded the wpf control in to my  Winforms.

    I have a few different ellipses in my wpf custom control and they all have a mouse down event handler, and in run time went i click on a ellipses, I can change their color ,  but my question is how do I seen that information to my winform application from my wpf? 

    I tried this :

     private void elementHost1_ChildChanged(object sender, System.Windows.Forms.Integration.ChildChangedEventArgs e)
                int stop =0;
      private void Ellipse_MouseDown(object sender, MouseButtonEventArgs e)
                Ellipse EP = sender as Ellipse;
                string tempS = EP.Name;
                EP.Fill = Brushes.Green;
                int you = 0;

    The ellipse will change color, but the  elementHost1_ChildChanged event is not being called.

    Thank you for posting here.

    >>The ellipse will change color, but the elementHost1_ChildChanged event is not being called.

    I have tested the code according to your description. I think you misunderstand the ChildChanged event.

    It occurs when the Child property is set instead of wpf usercontrol has been changed.

    Hope my explanation could be helpful.

    Best Regards,
