在 silverlight 中开始加载事件的故事板

我正在查看 Prism Stocktrader RI，我可以看到 InTransition Storyboard 是使用代码来播放的。我尝试了以下 xaml：

    <UserControl.Triggers>
        <EventTrigger RoutedEvent="UserControl.Loaded">
            <BeginStoryboard Storyboard="{StaticResource InTransition}"/>
        </EventTrigger>
    </UserControl.Triggers>

But it gives the following error on InitializeComponent (i.e. a XamlParseException):
enter image description here

any idea why?

I am looking at the Prism Stocktrader RI and I can see that the InTransition Storyboard is played using code. I tried the following xaml:

    <UserControl.Triggers>

        <EventTrigger RoutedEvent="UserControl.Loaded">

            <BeginStoryboard Storyboard="{StaticResource InTransition}"/>

        </EventTrigger>

    </UserControl.Triggers>

But it gives the following error on InitializeComponent (i.e. a XamlParseException):

any idea why?

我认为触发器在 Silverlight 中不可用。

您可以使用 ControlStoryboardAction 行为在 xaml 中调用故事板，如下所示（您将需要 Microsoft.Expression.Interactions.dll 和 System.Windows.Interactivity.dll），

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" 
xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions" 

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Loaded">
        <ei:ControlStoryboardAction Storyboard="{StaticResource InTransition}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

注意：您可以删除 EventName ='Loaded' 因为'Loaded' 是该控件的默认事件。

I think triggers are not available in Silverlight.

You can use a ControlStoryboardAction behavior to call a storyboard in xaml, like the following (you will need Microsoft.Expression.Interactions.dll and System.Windows.Interactivity.dll),

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" 
xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions" 

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Loaded">
        <ei:ControlStoryboardAction Storyboard="{StaticResource InTransition}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

Note: you can remove EventName='Loaded' as 'Loaded' is the default event for this control.
