AddDeleteThemeTransition Class
Definition
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. (Inherited from DependencyObject) |
