Overriding IsEnabled

04-08-2009 7:16 AM |

I would like to set IsEnabled to false for a particular usercontrol, and have that setting automatically be inherited by all children of that control. But then I would like to override that value for some of the children. See the example below. I want the first button to be enabled, and the rest to inherit the setting on the parent user control (IsEnabled=false). But all the children are disabled no matter what I do. Is there a way of accomplishing this? It seems logical to me that the setting on a child should override the setting on the parent.

<UserControl x:Class="SilverlightApplication3.MyUserControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:local="clr-namespace:SilverlightApplication3"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             Width="400"
             Height="300"
             IsEnabled="False">
    <Grid x:Name="LayoutRoot"
          Background="White">
        <StackPanel>
            <Button Content="Btn1" IsEnabled="True"></Button>
            <Button Content="Btn2"></Button>
            <Button Content="Btn3"></Button>
        </StackPanel>
    </Grid>
</UserControl>

This is the way it has always worked in Windows and there is very little chance of Microsoft adding this kind of functionality in a future release of Silverlight or even WPF.

Well, I've posted it on the wishlist for SL3 now, so we'll see what happens.
