Не знаю подходит ли решение, но вот:

using System.Windows;
using System.Windows.Media;

// Call AddVisualChild and AddLogicalChild so the element hosting these visuals
// knows about them and are accounted for in the layout process. This is what
// Gets custom visuals actually rendered.
AddVisualChild( drawingVisual );

}

}
}

}
