从DataTemplate.Triggers绑定

Question

我正在尝试为MyAnimation做绑定工作，类似于工作中的MyHeight。我的身高正常工作，但我找不到一种方法使MyAnimation绑定到某个东西上。

    <DataTemplate
        x:Key="MyTemplate"
        DataType="MyNotification">
        <Grid
            x:Name="MyNotificationWindow" ...
            Height="{Binding Path = MyHeight}"
            >
            ....
        </Grid>
        <DataTemplate.Triggers>
            <EventTrigger
                RoutedEvent="Window.Loaded"
                SourceName="MyNotificationWindow">
                <BeginStoryboard
                    x:Name="MyStory">
                    <Storyboard>
                        <DoubleAnimation
                            Storyboard.TargetName="MyNotificationWindow"
                            From="0.01"
                            To="1"
                            Storyboard.TargetProperty="Opacity"
                            Duration="{Binding Path=MyAnimation, RelativeSource={RelativeSource TemplatedParent}}"
                            />
            ....
        </DataTemplate.Triggers>

谢谢!

我认为问题是这样的：{Binding Path=MyAnimation, RelativeSource={RelativeSource TemplatedParent}}应该是{Binding Path=DataContext.MyAnimation, RelativeSource={RelativeSource Self}}

试试这个，这可能就是问题所在。
