MVVM- 在 Silverlight 中的视图模型中触发情节提要 [英] MVVM- Trigger Storyboard in the View Model in Silverlight

问题描述

在我看来，如果可能，我想从 ViewModel 触发几个故事板.有没有一种简单的方法或优雅的方法来做到这一点.这就是我想要做的.

I have a couple of Storyboards in my view that I would like to trigger from the ViewModel if possible. Is there a simple way or elegant way of doing this. Here is what I am trying to do.

人点击按钮-->RelayCommand(在ViewModel中)，然后Relay Command应该播放故事板.还有一件事，我还想在没有任何交互的情况下在 ViewModel 中自行触发故事板动画.

Person Clicks on a Button-->RelayCommand (In the ViewModel), the Relay Command should then play the storyboard. Also one more thing, I would like to also trigger the storyboard animation by itself in the ViewModel without any interaction.

    <i:Interaction.Triggers>
 <i:EventTrigger EventName="MouseLeftButtonDown">
    <cmd:EventToCommand Command="{Binding ButtonPress}"                                                     CommandParameterValue="RedButtonLight">
    </cmd:EventToCommand>
         </i:EventTrigger>
          </i:Interaction.Triggers> 

推荐答案

我知道这是很久以前的事了.但我写了一篇关于触发故事板和 MVVM 的详细博客文章.

I know it's a long time ago. But I've written a detailed blog post about Triggering Storyboards and MVVM.
