Popup.Closed 事件

定义

重要

一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。

当 IsOpen 属性更改为 false 时发生。

public:
 event EventHandler ^ Closed;

public event EventHandler Closed;

member this.Closed : EventHandler

Public Custom Event Closed As EventHandler

以下示例演示如何为 Closed 事件定义事件处理程序。

private void PopupClosing(object sender, EventArgs e)
{
    //Code to execute when Popup closes
}

Private Sub PopupClosing(ByVal sender As Object, ByVal e As EventArgs)
    'Code to execute when Popup closes
End Sub

<DockPanel>
  <Popup Closed="PopupClosing">
    <TextBlock Background="Yellow">Popup Text</TextBlock>
  </Popup>
</DockPanel>

Popup通过切换 IsOpen 属性打开和关闭。
