Zoom the drop indicator
posted

Hi!

When I zoom my LayoutRoot the drop indicator doesn't recognize it. How can I zoom the drop indicator too?

Class MainWindow 
    Dim st As New ScaleTransform()
    Private Sub Zoom()
        Dim tg = New TransformGroup
        st.ScaleX = 1
        st.ScaleY = 1
        tg.Children.Add(st)
        LayoutRoot.LayoutTransform = tg
        st.ScaleX = st.ScaleX * 1.5
        st.ScaleY = st.ScaleY * 1.5
    End Sub
End Class

    Hello Voks,

     

    In order to avoid this behavior you can use the following approach:

     

    1.       Handle XamDockManager’s PaneDragStarting event.

    2.       In the event handler for the PaneDragStarting event put the following code lines in order to zoom the drag indicator using RenderTransform:

     

                LayoutRoot.RenderTransform = LayoutRoot.LayoutTransform

                LayoutRoot.LayoutTransform = New TransformGroup

     

    3.       Handle XamDockManager’s PaneDragEnded event

    4.       In its event handler put the following code lines in order to return to LayoutTransform and keep the functionality that you want:

     

                LayoutRoot.LayoutTransform = LayoutRoot.RenderTransform

                LayoutRoot.RenderTransform = New TransformGroup

     

    If you require any further assistance on the matter please do not hesitate to ask.

     

    Sincerely,
