ReorderThemeTransition Class
Definition
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.
<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>

{

(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. |

DispatcherQueue |
Gets the DispatcherQueue that this object is associated with. The DispatcherQueue 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) |
