The ItemRemovedAnimation property can be used to define animations for visual items being removed out of the viewport of RadDataBoundListBox. The ItemRemovedAnimation is also used when the control's ItemsSource property is reset and all items are animated out of the viewport in sequential manner. In this context, the ItemRemovedAnimationInterval is used to define the time interval between the start of each separate item animation in the batch operation.
The following code sample demonstrates how to define an animation for items removed out of the viewport in XAML:
<telerikDataControls:RadDataBoundListBox.ItemRemovedAnimation> <telerikCore:RadFadeAnimation Duration="0:0:10"> <telerikCore:RadFadeAnimation.Easing> <CubicEase EasingMode="EaseIn"/> </telerikCore:RadFadeAnimation.Easing> </telerikCore:RadFadeAnimation> </telerikDataControls:RadDataBoundListBox.ItemRemovedAnimation>
After defining an animation for items removed out of the viewport, it will be used each time an item is removed from the source collection and it has to be removed from the viewport. Also, when the ItemsSource property is reset, all items that are realized in the viewport will be animated in batch using the ItemRemovedAnimation.
When items are animated using the ItemRemovedAnimation in batch, the ItemRemovedAnimationInterval is used to define the time interval between two separate animations started for given realized items. This interval creates a delay for each animation so that items are animated sequentally.
By default, the ItemRemovedAnimationInterval property has its default value set to 50 milliseconds.
