Animation not working

[Stephan]

Hi Telerik Team,

I looked into the documentation and the tutorial video to add animation to a RadDataBoundListBox without any success. What am I missing here?

<telerikPrimitives:RadDataBoundListBox
    Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3"
    ItemsSource="{Binding WorkDays}"
    DataContext="{Binding Source={StaticResource Locator}, Path=WorkDay, Mode=OneWay}"
    ItemAnimationMode="PlayAll">

    <telerikPrimitives:RadDataBoundListBox.ItemAddedAnimation>
        <telerik:RadMoveAnimation StartPoint="500,0" EndPoint="0,0" Duration="0:0:1">
            <telerik:RadMoveAnimation.Easing>
                <CubicEase EasingMode="EaseInOut"></CubicEase>
            </telerik:RadMoveAnimation.Easing>
        </telerik:RadMoveAnimation>
    </telerikPrimitives:RadDataBoundListBox.ItemAddedAnimation>
    <telerikPrimitives:RadDataBoundListBox.ItemRemovedAnimation>
        <telerik:RadMoveAnimation StartPoint="0,0" EndPoint="500,0" Duration="0:0:1">
            <telerik:RadMoveAnimation.Easing>
                <CubicEase EasingMode="EaseInOut"></CubicEase>
            </telerik:RadMoveAnimation.Easing>
        </telerik:RadMoveAnimation>
    </telerikPrimitives:RadDataBoundListBox.ItemRemovedAnimation>

    <telerikPrimitives:RadDataBoundListBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid x:Name="ListBoxWorkDaysItem"
                      HorizontalAlignment="Stretch"
                      VerticalAlignment="Top"
                      Background="{StaticResource TsColorVariant3}"
                      Margin="0,0,0,2"
                      d:DataContext="{d:DesignInstance model:WorkDay}">
                    ...
                </Grid>
            </Grid>
        </DataTemplate>
    </telerikPrimitives:RadDataBoundListBox.ItemTemplate>
</telerikPrimitives:RadDataBoundListBox>

I'm using VS 2013 Ultimate Update 2 with Telerik UI for WP 2014.1 0226 on a new WP8.1 Silverlight project.

Hello Stephan,

I have taken a look at our code and have identifies a potential problem that causes this behaviour on your side.

The reason for it is that when the source from the binding comes, an animation start is attempted but the values for the Added/Removed animations are not yet initialized by the XAML parser. We just need to refactor our code to not check for these values at this point and this will fix the issue.

For the time being, I can suggest a workaround to programmatically bind the control to a data source to be able to see the animations.

I hope this is helpful.
