Question

I have the following ItemTemplate:

    <ItemsControl ItemsSource="{Binding Topics}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal" Margin="10,0">
                    <TextBlock Text="{Binding FallbackValue='topic name', Converter={StaticResource topicToStrConverter}}" 
                               Margin="10,0"
                               VerticalAlignment="Center" />
                    <Button HorizontalAlignment="Right">
                        <Image Source="Images/appbar.cancel.rest.png" />
                    </Button>
                </StackPanel>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

I would like to right-align all of the buttons regardless of the length of their corresponding text, but I’m not sure how to do it.

I’m using Silverlight 4.

Your panel doesn’t have a set length, so there’s nothing to define where you want the right edge to be. If you put the items into a StackPanel or Grid with a fixed Width, you’ll see the behavior you expect.
