Public NotInheritable Class LayoutInformation

NameDescription
System_CAPS_pubmethodSystem_CAPS_staticGetLayoutClip(FrameworkElement)

Returns a Geometry that represents the visible region of an element.

System_CAPS_pubmethodSystem_CAPS_staticGetLayoutExceptionElement(Dispatcher)

Returns a UIElement that was being processed by the layout engine at the moment of an unhandled exception.

System_CAPS_pubmethodSystem_CAPS_staticGetLayoutSlot(FrameworkElement)

Returns a Rect that represents the layout partition that is reserved for a child element.

The following example demonstrates how to use the GetLayoutSlot method to translate the bounding box of a FrameworkElement into a GeometryDrawing.

Private Sub getLayoutSlot1(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim myRectangleGeometry As New RectangleGeometry
    myRectangleGeometry.Rect = LayoutInformation.GetLayoutSlot(txt1)
    Dim myGeometryDrawing As New GeometryDrawing
    Dim myPath As New Path
    myPath.Data = myRectangleGeometry
    myPath.Stroke = Brushes.LightGoldenrodYellow
    myPath.StrokeThickness = 5
    Grid.SetColumn(myPath, 0)
    Grid.SetRow(myPath, 0)
    myGrid.Children.Add(myPath)
    txt2.Text = "LayoutSlot is equal to " + LayoutInformation.GetLayoutSlot(txt1).ToString()
End Sub
