VisualBrush is a new addition to the brush types since GDI+.  A VisualBrush is used to fill UI elements. The following code uses a VisualBrush to fill a rectangle. I will cover VisualBrush object, its methods and properties in more details in my seperate article.
 

<Rectangle Width="200" Height="100" Stroke="Black" StrokeThickness="1"> 

    <Rectangle.Fill>

        <VisualBrush Viewport="0,0,200,100" Viewbox="0,0,100,100"

ViewportUnits="Absolute" Stretch="Fill" >

            <VisualBrush.Visual>                           

                <Canvas>

                    <Grid Width="100" Height="100" >                                   

                        <RowDefinition Height="20"/>                                      

                        <RowDefinition Height="50"/>

                        <RowDefinition Height="30"/>                                    

                        <Rectangle Grid.Row="0" Fill="Black"/>                                      

                        <Rectangle Grid.Row="1" Fill="Yellow"/>                                       

                        <Rectangle Grid.Row="2" Fill="Green"/>                                   

                    </Grid>

                </Canvas>                        

            </VisualBrush.Visual>                  

        </VisualBrush>

    </Rectangle.Fill>

</Rectangle>

 

The output looks like Figure 1.
