故事板 - 从代码隐藏设置目标名称 [英] StoryBoard - Set Target Name from code-behind

问题描述

我有故事板资源

<预类=郎咸平的XML prettyprint-覆盖> <窗​​口的.resources>
<情节提要X：键=衰落Storyboard.TargetName =NotifyWindowStoryboard.TargetProperty =透明度>
将; DoubleAnimation是从=1要=0时长=0：0：1>
< / DoubleAnimation是>
< /故事板>
< /Window.Resources>


和上的windowClosing我有下面的代码

 私人无效NotifyWindow_Closing（对象发件人，System.ComponentModel.CancelEventArgs E）
 {
故事板褪色= this.Resources [衰落]作为故事板; 
如果（衰减= NULL&放大器;！&安培;！fadingCompleted）
 {
 fading.Completed + = FadingStoryBoard_Completed; 
 fading.Begin（）; 
 e.Cancel = TRUE; 
} 
} 
 
私人无效FadingStoryBoard_Completed（对象发件人，EventArgs五）
 {
 fadingCompleted = TRUE; 
关闭（）; 
 fadingCompleted = FALSE; 
} 
  

这工作得很好，但我想这个故事板移动到另一个组件。所以我需要指定 StoryBoard.TargetName 表单代码。我如何能做到这一点。

解决方案

附加属性可以通过名为静态辅助方法代码进行设置： 设置+属性名

请参阅C＃示例的here ：

  Storyboard.SetTargetName（ yourAnimationNotifyWindow）; 
  

I have StoryBoard in resources

  <Window.Resources>
    <Storyboard x:Key="Fading" Storyboard.TargetName="NotifyWindow" Storyboard.TargetProperty="Opacity" >
        <DoubleAnimation From="1" To="0" Duration="0:0:1">
        </DoubleAnimation>
    </Storyboard>
  </Window.Resources>

And on WindowClosing I have next code

private void NotifyWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    Storyboard fading = this.Resources["Fading"] as Storyboard;
    if (fading != null && !fadingCompleted)
    {
        fading.Completed += FadingStoryBoard_Completed;
        fading.Begin();
        e.Cancel = true;
    }
}

private void FadingStoryBoard_Completed(object sender, EventArgs e)
{
   fadingCompleted = true;
   Close();
   fadingCompleted = false;
}

And this works fine, But I want to move this storyboard to another assembly. So i need to specify StoryBoard.TargetName form code. How can I do that?

解决方案

Attached properties can be set from code via static helper methods named: "Set" + PropertyName

See C# example here:

Storyboard.SetTargetName(yourAnimation, "NotifyWindow");
