从模板访问StoryBoard
从模板访问StoryBoard

下面是我得到的一些类：

</Style>如你所见，我有3个不同的故事板，其中两个发生在特定的触发器上。我还有第三个(BtnRevert)，我想按需启动。我似乎真的不知道该怎么做。这是可能的吗?如果是，我如何绕过它?如果不是，我如何绕过它？
编辑:所以我试了一下：
Dim s As Storyboard = _oCurMenuBouton.Template.Resources("BtnRevert")
s.Begin()它似乎得到了正确的故事板，但现在我得到了：
No applicable name scope exists to resolve the name 'rectangle'.它似乎没有认识到故事板是我的按钮的属性，或者至少是模板的属性。有没有办法让它工作呢？
让它起作用了！这就是答案
Dim s As Storyboard = _oCurMenuBouton.Template.Resources("BtnRevert")
s.Begin(_oCurMenuBouton,_oCurMenuBouton,Template)谢谢

试试看这个
<Button Height="25"
Margin="5"
Style="{StaticResource BoutonMenu}" Click="Button_Click"></Button>在后台代码中
private void Button_Click(object sender, RoutedEventArgs e)
{
var rButton = sender as Button;
if (rButton != null)
{
Storyboard s = (Storyboard)rButton.Template.Resources["BtnRevert"];
}
