<Canvas /> element of XAML represents a canvas. A canvas defines an area within which you can explicitly position child elements by coordinates relative to the canvas area.

Now let's say you want to draw some text which is relative to a canvas, not the parent window. The following code draws a border around the canvas and draws a canvas which is aligned to center horizontally and vertically.

<Border

       BorderThickness="3"

       BorderBrush="Black"

       Background="Yellow"

       HorizontalAlignment="Center"

       VerticalAlignment="Center"

       Width="200"

       Height="100">   

    <Canvas>             

        <TextBlock Canvas.Top="30" Canvas.Left="50">Hello XAML!</TextBlock>          

    </Canvas>      

</Border>


The output looks like Figure 1.

As you can see from Figure 1, the text is drawn on a relative position to the canvas.
