[WPF] How to Stop an Animation

[Richard Andrew x64]

It appears that the Storyboard won't accept a new RepeatBehavior structure once the animation has already begun. I want to have an animation repeat endlessly, until the user clicks the window. I have the animation RepeatBehavior set to Forever in the XAML. How do I stop the animation once it's begun?

The difficult we do right away... ...the impossible takes slightly longer.

Change the RepeatBehavior and call Stop()

Thanks.

A Stop() call on the StoryBoard should be sufficient. You don't need to do anything else.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Another alternative maybe...all in XAML...

<Grid Name="theGrid" Background="SteelBlue" >
    <Grid.Triggers>
        <EventTrigger RoutedEvent="Grid.Loaded">
            <BeginStoryboard x:Name="gridBeginStoryboard" >
                <Storyboard>
                    <DoubleAnimation Storyboard.TargetName="theGrid" 
                                     Storyboard.TargetProperty="Opacity"
                                     From="1.0" To="0.0" Duration="0:0:2" 
                                     AutoReverse="True" RepeatBehavior="Forever" />
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
        <EventTrigger SourceName="theGrid" RoutedEvent="Grid.MouseLeftButtonDown">
            <StopStoryboard BeginStoryboardName="gridBeginStoryboard" />
        </EventTrigger>
    </Grid.Triggers>
</Grid>
