#839 – A Label’s Target Could Have Its Own Label

You typically set the Target of a Label to a control that doesn’t have its own label.  The purpose is that when the user presses the Label’s access key, the target control will receive focus.

There’s nothing preventing you, however, from specifying the Target as a control that would normally have its own caption.

For example, you normally set a Button’s access key to one of the characters in its Content property–i.e. the text that appears on the face of the button.  In the example below, however, we use a Label to specify an access key for the Button, since the button’s content is just an asterisk character.  When you press the Label’s access key, the Button will activate.

    <StackPanel Orientation="Horizontal">
        <Label Content="_Calculate" VerticalAlignment="Center"
               Target="{Binding ElementName=btnCalc}"/>
        <Button Name="btnCalc" Content="*" VerticalAlignment="Center"
                Padding="10,5" Click="btnCalc_Click"/>
    </StackPanel>
