从DataTemplate.Triggers进行绑定

Question

I am trying to do my binding working for MyAnimation similar to the working one which is MyHeight. My Height is working properly, but I can not find a way to make the MyAnimation binds to something.

    <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>

Thank you!

I think the issue is the following : {Binding Path=MyAnimation, RelativeSource={RelativeSource TemplatedParent}} should be {Binding Path=DataContext.MyAnimation, RelativeSource={RelativeSource Self}}

Try this, it might be the issue.
