VSTO（文档级）：Excel中的单个上下文菜单（右键单击菜单）

是否可以通过C＃（VSTO）禁用或configuration（单元格，范围） 上下文菜单 。 如果是的话，我该如何实现它（在文档级的VSTO Excel应用程序中）

例如，我想禁用上下文菜单中的一些项目（例如复制/粘贴），并添加新的项目或replace标准的上下文菜单与一个完整的自己的菜单！

Smarttags是Excel中上下文菜单的一个很好的select吗？

Answer 1

• 以下是一些带有注释的粗略示例代码
• 这是在VS2010中创build的，并针对Excel 2010进行了testing
• 第一步是创build一个新的Excel 2010加载项目
• 然后将下面的示例代码添加到ThisAddin.cs中生成的默认代码中。
• 此代码将添加一个新的菜单项，并右键单击包含“abc”的单个单元格时删除剪切/复制/粘贴菜单项。 这是模拟根据单元格的内容来改变上下文菜单。
