silverlight 子控件相对父控件的位置

[kisstome88]

<Grid x:Name="LayoutRoot" Background="White" LayoutUpdated="LayoutRoot_LayoutUpdated" Loaded="LayoutRoot_Loaded" MouseMove="MapControl_MouseMove" MouseWheel="MapControl_MouseWheel" MouseLeftButtonDown="MapControl_MouseLeftButtonDown" MouseLeftButtonUp="MapControl_MouseLeftButtonUp" >
<Canvas x:Name="canvas" HorizontalAlignment="Left" VerticalAlignment="Top">

<TextBlock FontSize="50" Name="text1"></TextBlock>

</Canvas>
</Grid>

问：canvas相对于LayoutRoot的位置怎么获取啊？谢谢

Point pt = canvas.TransformToVisual(LayoutRoot).Transform(new Point());
Point pt = canvas.TransformToVisual(this).Transform(new Point());
