我有一个带.NET 4.0的C#VSTO应用程序,它在Globals.ThisAddIn.Application.CommandBars [" Cell"]上下文菜单中使用了两个自定义CommandBarButtons。我在ThisAddIn_Startup事件上创建了一次按钮,它们可以很好地用于所有工作簿。如果我的插件在某些时候关闭但没有关闭Excel,那么如果有超过1个打开的工作簿就会出现问题。只有活动工作簿的右键单击上下文菜单才会删除按钮。
代码:
public partial class ThisAddIn
{
private const string TAG_PASTE_EVENT = "PASTE EVENT";
private const string TAG_COPY_EVENT = "COPY EVENT";
private Office.CommandBarButton copy_event, paste_event;
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
try
{
DefineShortcutMenu();
/*
* Other start up stuff that works fine
*/
}
catch (Exception ex)
{
ExceptionHandler.HandleException(ex);
}
}
private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
{
/*
* Other shut down stuff that works fine
*/
// Remove the right click menu buttons
foreach (Office.CommandBarControl control in Application.CommandBars["Cell"].Controls)
{
if (control.Tag.Equals(TAG_PASTE_EVENT))
{
control.Delete(true);
}
else if (control.Tag.Equals(TAG_COPY_EVENT))
{
control.Delete(true);
}
}
}
private void copy_event_Click(Office.CommandBarButton Ctrl, ref bool CancelDefault)
{
// Copy code
}
private void paste_event_Click(Office.CommandBarButton Ctrl, ref bool CancelDefault)
{
// Paste code
}
private void DefineShortcutMenu()
{
// Create and add the paste button
paste_event = (Office.CommandBarButton)Application.CommandBars["Cell"].Controls.Add(Office.MsoControlType.msoControlButton, missing, missing, 1, true);
paste_event.Style = Office.MsoButtonStyle.msoButtonCaption;
paste_event.Caption = "Paste Event";
paste_event.Tag = TAG_PASTE_EVENT;
paste_event.DescriptionText = "Stuff happens";
paste_event.Enabled = false;
paste_event.Click += paste_event_Click;
// Create and add the copy button
copy_event = (Office.CommandBarButton)Application.CommandBars["Cell"].Controls.Add(Office.MsoControlType.msoControlButton, missing, missing, 1, true);
copy_event.Style = Office.MsoButtonStyle.msoButtonCaption;
copy_event.Caption = "Copy Event";
copy_event.Tag = TAG_COPY_EVENT;
copy_event.DescriptionText = "Stuff happens";
copy_event.Enabled = false;
copy_event.Click += copy_event_Click;
}

我使用Excel 2013,我知道有一个与右键单击上下文菜单有关的错误(这就是为什么我使用foreach作为CommandBarControls而不是使用全局变量)。您发现工作的任何工作流程都会非常感谢!
TO CLARIFY:一切正常,唯一的问题是如果Add In关闭,CommandBarButtons不会从非活动工作簿的右键单击上下文菜单中删除。如果在同一会话期间重新打开“添加”,则会再次为所有工作簿提供“复制”和“粘贴”按钮,这意味着其上下文菜单未正确更新的工作簿现在具有2个“复制”按钮和2个“粘贴”按钮。

Office 2010不推荐使用命令栏。您需要使用Fluent UI控件。
