Enable child control if parent is disabled

I have a button containing a hyperlink, for example:

<Button IsEnabled="False"> <Hyperlink IsEnabled="True">Testing</Hyperlink> </Button>

I need to enable the hyperlink, however the button that needs to be disabled. How can I achieve this?

The above simply causes both controls to be disabled.

The Hyperlink control is weird with the IsEnabled property. In addition to what you mentioned, namely, full inheritance from the parent, there is another similar one.

Hyperlink for a specific control that has been disabled ( IsEnabled="False" ), setting ( IsEnabled="True" ) will not update the Hyperlink property. Solution - use relative source for Hyperlink (more info ).

To solve your question, I decided that this is not a standard solution. So I created a Class with my own dependency properties. It has the property MyIsEnabled and MyStyle . As you can guess from the name, the first sets its IsEnabled property and MyStyle needs to specify the button style, imitating the behavior of IsEnabled="False" .

SimulateDisable Style

 <Style x:Key="SimulateDisable" TargetType="{x:Type Button}"> <Setter Property="Opacity" Value="0.5" /> <Setter Property="Background" Value="Gainsboro" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Border CornerRadius="4" BorderThickness="1" BorderBrush="DarkBlue" SnapsToDevicePixels="True"> <ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style>

Define Button with your properties:

 <Button Name="MyButton" local:MyClass.MyIsEnabled="False" local:MyClass.MyStyle="{StaticResource SimulateDisable}" Width="100" Height="30" Click="Button_Click"> <Hyperlink IsEnabled="True" Click="Hyperlink_Click">Testing</Hyperlink> </Button>

Listing of MyClass

 public class MyClass : DependencyObject { public static readonly DependencyProperty MyIsEnabledProperty; public static readonly DependencyProperty MyStyleProperty; #region MyIsEnabled public static void SetMyIsEnabled(DependencyObject DepObject, bool value) { DepObject.SetValue(MyIsEnabledProperty, value); } public static bool GetMyIsEnabled(DependencyObject DepObject) { return (bool)DepObject.GetValue(MyIsEnabledProperty); } #endregion MyIsEnabled #region MyStyle public static void SetMyStyle(DependencyObject DepObject, Style value) { DepObject.SetValue(MyStyleProperty, value); } public static Style GetMyStyle(DependencyObject DepObject) { return (Style)DepObject.GetValue(MyStyleProperty); } #endregion MyStyle static MyClass() { MyIsEnabledProperty = DependencyProperty.RegisterAttached("MyIsEnabled", typeof(bool), typeof(MyClass), new UIPropertyMetadata(false, OnPropertyChanged)); MyStyleProperty = DependencyProperty.RegisterAttached("MyStyle", typeof(Style), typeof(MyClass), new UIPropertyMetadata(OnPropertyChanged)); } private static void OnPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { Button MyButton = sender as Button; bool MyBool = GetMyIsEnabled(MyButton); if (MyBool == false) { MyButton.Style = MyClass.GetMyStyle(MyButton); } } }

Plus for a Hyperlink event indicating e.Handled = true so that the event does not follow.

 private void Hyperlink_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Hyperlink Click!"); e.Handled = true; } private void Button_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Button Click! Don't show it's!"); }

Output
