Edit

Provides the animated transition behavior for when controls add or delete children of a panel. For example, if you have a collection of photos displayed in a Grid, you can associate this animation to the Grid so that when photos are added or deleted, the photos will animate in and out of view.

Examples

The following example shows how to use the AddDeleteThemeTransition to animate rectangles as they are added and deleted from a panel. Notice how the other child elements of the panel re-flow when one of them is removed.

<Button Content="Add Rectangle" Click="AddButton_Click"/>
<Button Content="Remove Rectangle" Click="RemoveButton_Click"/>


<ItemsControl Grid.Row="1" x:Name="rectangleItems">
    <ItemsControl.ItemContainerTransitions>
        <TransitionCollection>

            <!-- You use AddDeleteThemeTransition 
                 in panels like in a WrapGrid. -->
            <AddDeleteThemeTransition/>
        </TransitionCollection>
    </ItemsControl.ItemContainerTransitions>
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapGrid Height="400"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

</ItemsControl>

private void RemoveButton_Click(object sender, RoutedEventArgs e)
{
    if (rectangleItems.Items.Count > 0)
        rectangleItems.Items.RemoveAt(0);
}

private void AddButton_Click(object sender, RoutedEventArgs e)
{
    Color rectColor = new Color();
    rectColor.R = 200;
    rectColor.A = 250;
    Rectangle myRectangle = new Rectangle();
    myRectangle.Fill = new SolidColorBrush(rectColor);
    myRectangle.Width = 100;
    myRectangle.Height = 100;
    myRectangle.Margin = new Thickness(10);
    rectangleItems.Items.Add(myRectangle);

}

Constructors

Properties

Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
