Binding to a property on AnimationType

[nathanAjacobs]

Is it possible to bind a property on AnimationType to a page's ViewModel?

This is not working for me, the opacity just stays at the default 0.3:

<Grid HorizontalOptions="FillAndExpand"
      VerticalOptions="FillAndExpand"
      BackgroundColor="Red">
    <Grid.Behaviors>
        <toolkit:AnimationBehavior>
            <toolkit:AnimationBehavior.AnimationType>
                <toolkit:FadeAnimation Opacity="{Binding OffOpacity}" />
            </toolkit:AnimationBehavior.AnimationType>
        </toolkit:AnimationBehavior>
    </Grid.Behaviors>
</Grid>

That should in theory work given the property is bindable. There might be an issue with the BindingContext not being inherited down. To prove that you could try manually setting the BindingContext on the FadeAnimation and see if that solves it.

Thanks, yeah that was it. Setting it manually makes it work.

<Grid HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" BackgroundColor="AliceBlue">
    <Grid.Behaviors>
        <toolkit:AnimationBehavior>
            <toolkit:AnimationBehavior.AnimationType>
                <toolkit:FadeAnimation Opacity="{Binding OffOpacity}" BindingContext="{Binding BindingContext, Source={x:Reference VideoPage}}"/>
            </toolkit:AnimationBehavior.AnimationType>
        </toolkit:AnimationBehavior>
    </Grid.Behaviors>
</Grid>
