Right align last element on StackPanel

[tom-huntington]

HorizontalAlignment="Right" does not work in the following

<StackPanel Orientation="Horizontal" >
    <TextBlock VerticalAlignment="Center" Text="Enter Number"/>
    <NumberBox HorizontalAlignment="Right"/>
</StackPanel>

What do people do? Use a grid with

<Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"/>
    <ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>

You can always write a custom Panel to achieve this,
just implement measure & arrange logic by yourself

[tom-huntington]

Are you sure? When I looked into the source code, it didn't appear they exposed the ability to override measure.

[Lightczx]

StackPanel can't be inherited, you need to inherit from Panel and write all logic yourself.
