的EventTrigger绑定到事件的DataContext从 [英] EventTrigger bind to event from DataContext

问题描述

我试图完成这样的事情：

 < DataTemplate.Triggers> 
<的EventTrigger RoutedEvent ={结合MyEvent}> 
< BeginStoryboard故事板={StaticResource的MyAnimation}/> 
< /&的EventTrigger GT; 
< /DataTemplate.Triggers> 
  

MyEvent是从我的DataContext的事件。

这不起作用，因为RoutedEvent不能绑定表达式。任何想法如何做到这一点？
其实，我需要的EventTrigger和DataTrigger ...

与混合SDK解决方案的一些组合：

 <交互：Interaction.Triggers> 
<交互性：的EventTrigger SourceObject ={结合}事件名称=MyEvent> 
< EI：ControlStoryboardAction ControlStoryboardOption =播放> 
< EI：ControlStoryboardAction.Storyboard> 
<情节提要> 
 .... 
< /故事板> 
< / EI：ControlStoryboardAction.Storyboard> 
< / EI：ControlStoryboardAction> 
< /交互：&的EventTrigger GT; 
< /交互性：Interaction.Triggers> 
  

解决方案

从使用EventTriggers交互（混合SDK ）可以触发在任何物体上任何情况下，本机的人只对 RoutedEvents ，你通常只对控制工作。

I'm trying to accomplish something like this:

<DataTemplate.Triggers>
    <EventTrigger RoutedEvent="{Binding MyEvent}">
        <BeginStoryboard Storyboard="{StaticResource MyAnimation}" />
    </EventTrigger>
</DataTemplate.Triggers>

MyEvent is event from my DataContext.

This does not work because RoutedEvent can't be Binding expression. Any idea how to accomplish this? In fact, I need some mix of EventTrigger and DataTrigger...

Solution with Blend SDK:

<Interactivity:Interaction.Triggers>
    <Interactivity:EventTrigger SourceObject="{Binding}" EventName="MyEvent">
        <ei:ControlStoryboardAction ControlStoryboardOption="Play">
            <ei:ControlStoryboardAction.Storyboard>
                <Storyboard>
                    ....
                </Storyboard>
            </ei:ControlStoryboardAction.Storyboard>
        </ei:ControlStoryboardAction>
    </Interactivity:EventTrigger>
</Interactivity:Interaction.Triggers>

解决方案

Using the EventTriggers from Interactivity (Blend SDK) can trigger on any event on any object, the native ones only work for RoutedEvents which you normally only have on controls.
