Movement of a user control that is on an image RRS feed

  • Question

  • I have a Windows 8 app and a user control. The user control moves along my finger in the right left and bottom movements. When I try to move up , the body of User control is there and unless I move out of it , its not moving up.

    as u can see in the image that my pointer is on the user control and I am trying to move up but its not happenning. The condition is like , I can click anywhere , the user control appears I can move it anywhere and even if my finger is on the user control , it should keep moving

  • Hi Apoorv,

    How did you place your Usercontrol on that image? How did you implement the moveable UserControl? Could you provide some code snippets?

    In my experience, we can place a Usercontrol and Image control into Canvas control, to make a moveable Usercontrol, we can handle ManipulationDelta event and use Transform, here is my sample:


            <Rectangle Width="100" Height="100" Fill="Red"
                       ManipulationDelta="Rectangle_ManipulationDelta" />

    private void Rectangle_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e)
                var _Rectangle = sender as Windows.UI.Xaml.Shapes.Rectangle;
                var _Transform = (_Rectangle.RenderTransform as CompositeTransform)
                    ?? (_Rectangle.RenderTransform = new CompositeTransform()) as CompositeTransform;
                _Transform.TranslateX += e.Delta.Translation.X;
                _Transform.TranslateY += e.Delta.Translation.Y;


    <Canvas Name="cv">
                <Image Width="{Binding ActualWidth,ElementName=cv}" Source="Assets/1.jpg" Stretch="Fill" />
                <local:MyUserControl1 />

  • Hi ,

         I am not using rectangle for Cropping . Actually I need to implement clipping in my code ! Cropping seems to be very slow for me
