AddDeleteThemeTransition Class

Definition

Namespace:: Windows.UI.Xaml.Media.Animation

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.

Equivalent WinUI class: Microsoft.UI.Xaml.Media.Animation.AddDeleteThemeTransition.

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

AddDeleteThemeTransition()

Initializes a new instance of the AddDeleteThemeTransition class.

Equivalent WinUI constructor: Microsoft.UI.Xaml.Media.Animation.AddDeleteThemeTransition.AddDeleteThemeTransition.

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.

Equivalent WinUI property: Microsoft.UI.Xaml.DependencyObject.Dispatcher.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ClearValue. (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. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetAnimationBaseValue. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.GetValue. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.ReadLocalValue. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.RegisterPropertyChangedCallback. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.SetValue. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. Equivalent WinUI method: Microsoft.UI.Xaml.DependencyObject.UnregisterPropertyChangedCallback. (Inherited from DependencyObject)
