How to add a vertical Separator?

Question

I want to add a vertical Separator to a Grid, but i can only find the horizontal. Isn't there a Property, where you can enter if the line of the separator should be horizontal or vertical?

I searched a lot, but didn't find a short and easy solution to this.

I use .Net Framework 4.0 and Visual Studio Ultimate 2012.

If I try to rotate the horizontal Separator by 90 degrees, it loses the ability to "dock" to other Components.

The rotated separator looks like this:

<Separator HorizontalAlignment="Left" Height="100" Margin="264,26,0,0" VerticalAlignment="Top" Width="100" RenderTransformOrigin="0.5,0.5">
    <Separator.RenderTransform>
        <TransformGroup>
            <ScaleTransform/>
            <SkewTransform/>
            <RotateTransform Angle="90"/>
            <TranslateTransform/>
        </TransformGroup>
    </Separator.RenderTransform>
</Separator>

Answer 1

This should do exactly what the author wanted:

<StackPanel Orientation="Horizontal">
    <Separator Style="{StaticResource {x:Static ToolBar.SeparatorStyleKey}}" />            
</StackPanel>

if you want a horizontal separator, change the Orientation of the StackPanel to Vertical.
