WindowsFormsHost is always the most top from WPF element

Question

how to set the z-index windowsformhost that they are not always at the top of the WPF element ?

Answer 1

In my situation my WindowsFormsHost is in a two row Grid. The bottom row has a StackPanel in it that changes Height depending on what it contains. I handle that StackPanel's LayoutUpdated event to resize my WindowsFormsHost by subtracting it's ActualHeight from the Grid's ActualHeight. Be sure to use ActualHeight not Height.

     void ResizeWinhost()
    {
        mainGrid.UpdateLayout();
        detailPanel.UpdateLayout();
        winHost.Height = mainGrid.ActualHeight - detailPanel.ActualHeight - 5;
    }
