I have a more StackPanels in my XAML. Every StackPanel has a border inside. When I modify the Main Window the width follows the resizing. But the height follows only in one the bigger direction. If I make the Window smaller the height of the borders doesn't follows. So the effect is the Botton border line isn't visible. How can I do this ?
<Window x:Class="MyStackPanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MyCombobox" Height="356" Width="475">
<Grid>
<StackPanel x:Name="STP"
Margin="10">
<Border x:Name="STPB"
BorderBrush="#FFE80707"
BorderThickness="5"
CornerRadius="10"
Height="{Binding ElementName=STP,Path=ActualHeight}"/>
</StackPanel>
</Grid>
</Window>
