如何從樣式觸發器設置依賴屬性

我正在使用以下樣式集創建自定義wpf控件。在後面的代碼中，我有一個名爲selected的依賴屬性。當OnMouseLeftButtonDown觸發器被執行時，如何將此屬性設置爲true？如何從樣式觸發器設置依賴屬性

<Style TargetType="{x:Type local:myControl}"> 
     <Setter Property="Template"> 
      <Setter.Value> 
       <ControlTemplate TargetType="{x:Type local:myControl}"> 
        <ControlTemplate.Resources> 
         <Storyboard x:Key="OnMouseLeftButtonDown"> 
          <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" Storyboard.TargetName="border"> 
           <EasingColorKeyFrame KeyTime="0" Value="#FF9B1111"/> 
          </ColorAnimationUsingKeyFrames> 
         </Storyboard> 
        </ControlTemplate.Resources> 
        <ControlTemplate.Triggers> 
         <EventTrigger RoutedEvent="UIElement.MouseLeftButtonDown" SourceName="textBlock"> 
          <BeginStoryboard Storyboard="{StaticResource OnMouseLeftButtonDown}"/> 
         </EventTrigger> 
         <EventTrigger RoutedEvent="UIElement.MouseLeftButtonDown" SourceName="textBlock2"> 
          <BeginStoryboard Storyboard="{StaticResource OnMouseLeftButtonDown}"/> 
         </EventTrigger> 
        </ControlTemplate.Triggers> 
        <Border Background="{TemplateBinding Background}" 
          BorderBrush="{TemplateBinding BorderBrush}" 
          BorderThickness="{TemplateBinding BorderThickness}"> 
         <Border Name="border" BorderBrush="#FFDEDEDE" BorderThickness="1" Margin="1" > 
          <StackPanel Orientation="Horizontal"> 
           <TextBlock Name="textBlock" HorizontalAlignment="Left" Margin="2,1,2,3" Text="{TemplateBinding ElementName}" TextWrapping="Wrap" VerticalAlignment="Top" Foreground="#FF7C8CF1" FontSize="10" FontWeight="Bold"></TextBlock> 
           <TextBlock Name="textBlock2" HorizontalAlignment="Left" Margin="2,1,2,3" Text="{TemplateBinding ElementText}" TextWrapping="Wrap" VerticalAlignment="Top" Foreground="#FF75757A" FontSize="10" FontWeight="Bold"></TextBlock> 
          </StackPanel> 
         </Border> 
        </Border> 
       </ControlTemplate> 
      </Setter.Value> 
     </Setter> 
    </Style>

公共靜態只讀的DependencyProperty SelectedProperty = DependencyProperty.Register（「Selected」，typeof（bool），typeof（XliffElement），new PropertyMetadata（default（bool）））; public bool已選擇 { get {return（bool）GetValue（SelectedProperty）; } set {SetValue（SelectedProperty，value）; } } – John

我弄成這樣做的另一種方式。我改變控件的名稱PART_ElementName和PART_ElementText的我的確在OnApplyTemplate（）方法

 public override void OnApplyTemplate() 
     { 
      base.OnApplyTemplate(); 
      _elementName = Template.FindName("PART_ElementName", this) as TextBlock; 
      _elementText = Template.FindName("PART_ElementText", this) as TextBlock; 

      if (_elementName != null) _elementName.MouseLeftButtonDown += (sender, args) => SelectControl(); 
      if (_elementText != null) _elementText.MouseLeftButtonDown += (sender, args) => SelectControl(); 
     }

那麼下面我做的修改在SelectControl（）方法

在你StoryboardOnMouseLeftButtonDown在您可以添加ObjectAnimationUsingKeyFrames。示例：

<Storyboard x:Key="OnMouseLeftButtonDown"> 
    <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" Storyboard.TargetName="border"> 
     <EasingColorKeyFrame KeyTime="0" Value="#FF9B1111"/> 
    </ColorAnimationUsingKeyFrames> 

    <!-- xmlns:sys="clr-namespace:System;assembly=mscorlib" --> 
    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="YouTarget" Storyboard.TargetProperty="NameOfYourProperty"> 
     <DiscreteObjectKeyFrame KeyTime="0:0:0"> 
      <DiscreteObjectKeyFrame.Value> 
       <sys:Boolean>True</sys:Boolean> 
      </DiscreteObjectKeyFrame.Value> 
     </DiscreteObjectKeyFrame> 
    </ObjectAnimationUsingKeyFrames> 
</Storyboard>

對於附加依賴屬性必須這樣寫：

Storyboard.TargetProperty="(local:YourDependecyClass.IsSampleMyProperty)"

好吧，在我的情況下，「YouTarget」會是什麼？ – John

@約翰：你爲什麼設置你的財產來源？ –

當他們點擊控件上的任何地方時，我就想讓它發生。 – John
