TemplateBinding Dependency Properties in UserControls RRS feed

  • Question

  •  Hi,

    I have a user control that has a button set with the Style below. In fact I am trying to implement a LinkButton. It is working OK but I would like to make the text underlined when the mouse passes over it:

    <Style TargetType="Button" x:Key="LinkButtonStyle">
      <Setter Property="Template">
          <ControlTemplate TargetType="Button">
          <TextBlock x:Name="innerTextBlock" Text="{TemplateBinding Content}"
                     TextDecorations="{TemplateBinding TextDecoration}"
                     Width="Auto" Height="Auto" Margin="0,0,0,0"
                     Foreground="#FFE5E5E5" FontSize="11" Cursor="Hand" />

    The Button is defined like this:
    <Button x:Name="linkButton" Content="linkButton" BorderThickness="0,0,0,0"
            Style="{StaticResource LinkButtonStyle}"
            MouseEnter="linkButton_MouseEnter" MouseLeave="linkButton_MouseLeave"/>

    I have defined a dependency property called TextDecoration of type TextDecorationCollection and when the event MouseEnter occurs I set the property to TextDecorations.Underline. It compiles OK but when I run it I receive an error

    Blend says that the "Member TextDecoration is not recognized or is not accessible". TextDecoration is defined like this:

     public TextDecorationCollection TextDecoration {
                get { return (TextDecorationCollection) GetValue(TextDecorationProperty); }
                set { SetValue(TextDecorationProperty, value); }

            public static DependencyProperty TextDecorationProperty =
                DependencyProperty.Register("TextDecoration", typeof(TextDecorationCollection), typeof(LinkButton),
                                            new PropertyMetadata(new PropertyChangedCallback(LinkButton.OnTextDecorationPropertyChanged)));

            private static void OnTextDecorationPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) {

    What could be the problem ??? 

    Thanks in advance

  • I would suggest modifying the HyperlinkButton control's theme in Blend 2. (Or just using the HyperlinkButton, if you didn't know that existed.) That would be the easiest way to do it.
