ReorderThemeTransition Class

Definition

Namespace:

Windows.UI.Xaml.Media.Animation

Provides the animated transition behavior for when list-view controls items change order. Typically this is due to a drag-drop operation. Different controls and themes potentially have varying characteristics for the animations involved.

Examples

The following example applies a ReorderThemeAnimation to a set of rectangles. As the new rectangles are added to the set, the other rectangles animate around the new one.

XAML

<StackPanel>
    <Button x:Name="AddItemButton" Content="AddItem" Click="AddItemButton_Click"/>
    <ItemsControl x:Name="ItemsList">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <WrapGrid>
                    <WrapGrid.ChildrenTransitions>
<!-- Apply a ReorderThemeTransition that will run when child elements are reordered. -->
                        <TransitionCollection>
                            <ReorderThemeTransition/>
                        </TransitionCollection>
                    </WrapGrid.ChildrenTransitions>
                </WrapGrid>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <!-- Initial items. -->
        <Rectangle Width="100" Height="100" Fill="Red"/>
        <Rectangle Width="100" Height="100" Fill="Green"/>
        <Rectangle Width="100" Height="100" Fill="Blue"/>            
    </ItemsControl>            
</StackPanel>

C#

private void AddItemButton_Click(object sender, RoutedEventArgs e)
{
    Rectangle newItem = new Rectangle();
    Random rand = new Random();

    newItem.Height = 100;
    newItem.Width = 100;
    newItem.Fill = new SolidColorBrush(Color.FromArgb(255,
            (byte)rand.Next(0, 255), (byte)rand.Next(0, 255), (byte)rand.Next(0, 255)));

    // Insert a new Rectangle of a random color into the ItemsControl at index 2.
    ItemsList.Items.Insert(2, newItem);
}

Remarks

Note that setting the Duration property has no effect on this object since the duration is preconfigured.

Constructors

ReorderThemeTransition()

Initializes a new instance of the ReorderThemeTransition class.

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)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
