示例
以下示例演示如何使用 AddDeleteThemeTransition 在从面板中添加和删除矩形时对矩形进行动画处理。 请注意,删除其中一个子元素时面板的其他子元素是如何重新流动的。
<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);
}
构造函数

方法
ClearValue(DependencyProperty) |
清除依赖属性的本地值。 (继承自 DependencyObject) |
GetAnimationBaseValue(DependencyProperty) |
返回为依赖属性建立的任何基值,该基值适用于动画未处于活动状态的情况。 (继承自 DependencyObject) |
GetValue(DependencyProperty) |
从 DependencyObject 返回依赖属性的当前有效值。 (继承自 DependencyObject) |
ReadLocalValue(DependencyProperty) |
如果设置了本地值,则返回依赖属性的本地值。 (继承自 DependencyObject) |
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
注册通知函数,用于侦听此 DependencyObject 实例上对特定 DependencyProperty 的更改。 (继承自 DependencyObject) |
SetValue(DependencyProperty, Object) |
设置 DependencyObject 上依赖属性的本地值。 (继承自 DependencyObject) |
UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
取消以前通过调用 RegisterPropertyChangedCallback 注册的更改通知。 (继承自 DependencyObject) |
