Is there a way to specify the Z-order of an element in XAML???

Hi All,

I would like to design a button with two rectangles in it.

Around theese two rectangles a would like to have a border with rounded edges.

The problem no is that if I do it like to code below, I will see the edges of the rectangles and not the rounded edges of the border.

Do anyone have an idea to fix this problem

Thx!!

<Border BorderBrush="{StaticResource bordercolor}" BorderThickness="1" CornerRadius="5">

<DockPanel LastChildFill="True">

<Grid Width="20" DockPanel.Dock="Left">

<Rectangle Height="Auto">

<Rectangle.Fill>

<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">

<LinearGradientBrush.GradientStops>

<GradientStop Offset="0" Color="{StaticResource navigationstartcolor}" />

<GradientStop Offset="1" Color="{StaticResource navigationstopcolor}" />

</LinearGradientBrush.GradientStops>

</LinearGradientBrush>

</Rectangle.Fill>

</Rectangle>

<Polygon Points="10,2 10,17 1,10" Fill="{StaticResource forecolor}" VerticalAlignment="Center" HorizontalAlignment="Center" />

</Grid>

<Grid HorizontalAlignment="Stretch" Width="Auto">

<Rectangle>

<Rectangle.Fill>

<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">

<LinearGradientBrush.GradientStops>

<GradientStop Offset="0" Color="{StaticResource backstartcolor}" />

<GradientStop Offset="1" Color="{StaticResource backstopcolor}" />

</LinearGradientBrush.GradientStops>

</LinearGradientBrush>

</Rectangle.Fill>

</Rectangle>

<TextBlock TextWrapping="Wrap" ClipToBounds="True" Text="{TemplateBinding Property=Content}" VerticalAlignment="Center" HorizontalAlignment="Center" />

</Grid>
