Align Grid column to right
As you mentioned its an ItemTemplate of ListBox, what you can do is set HorizontalContentAlignment to Stretch.
<ListBox> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> </Style> </ListBox.ItemContainerStyle> </ListBox>
Try with this :
<Grid Background="Transparent" Margin="0,3"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Orientation="Horizontal"> <Image x:Name="Selected" Width="48" Height="48" VerticalAlignment="Center" Stretch="Uniform" HorizontalAlignment="Center"/> <TextBlock x:Name="Name" TextAlignment="Left" VerticalAlignment="Center" Margin="20,0" /> </StackPanel> <Image Grid.Column="1" x:Name="Selected" Width="48" Height="48" VerticalAlignment="Center" Stretch="Uniform" HorizontalAlignment="Right"/> </Grid>
