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.

XAML


<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);

}
