NamedRange.BeforeDoubleClick 事件 (2007 system)

更新： 2008 年 7 月

当在默认的双击操作之前双击 NamedRange 控件时发生。

命名空间：  Microsoft.Office.Tools.Excel
程序集：  Microsoft.Office.Tools.Excel.v9.0（在 Microsoft.Office.Tools.Excel.v9.0.dll 中）

语法

声明
Public Event BeforeDoubleClick As DocEvents_BeforeDoubleClickEventHandler
用法
Dim instance As NamedRange
Dim handler As DocEvents_BeforeDoubleClickEventHandler

AddHandler instance.BeforeDoubleClick, handler

public event DocEvents_BeforeDoubleClickEventHandler BeforeDoubleClick

备注

如果双击重叠的 NamedRange 控件，将对发生重叠的每个控件引发该事件。

示例

下面的代码示例创建一个 NamedRange，然后用文本 Delete 填充所有的单元格。若要测试事件，请右击某个单元格，以便在该范围周围出现一个边框，然后双击某个单元格即可清除该范围。

此版本针对的是文档级自定义项。
