VSTO 为 Outlook 功能区创建命令而不通过加载项代码添加到功能区？

Question

So super new at Outlook add-in's but I have created a VSTO add-in in C# for Outlook that is working. The function it does is triggered by a button on the ribbon which is added to the Add-Ins section on startup. I would prefer this not be added automatically by the add-in as it is now and instead be a command the user would add through the customize ribbon action in Outlook. I can use the customize ribbon function in Outlook to add this command to other ribbons and groups but so far have not figured out how to not add it to a ribbon through the add-in code and still have it available to customize.

Currently the button is created via XML not the ribbon designer. I have not included any code here since I'm not sure that any is needed for this question or what it would be if so.

Answer 1

Try to add visible="false" attribute to the button.

Answer 2

Instead of hard-coding the visible attribute set to false you may consider using ribbon callbacks where you could set the visibility of your ribbon controls at runtime dynamically. So, you could keep settings for displaying ribbon controls depending on the user's preferences. The getVisible callback has the following signature (depending on your programming language):

C#: bool GetVisible(IRibbonControl control)

VBA: Sub GetVisible(control As IRibbonControl, ByRef visible)

C++: HRESULT GetVisible([in] IRibbonControl *pControl, [out, retval] VARIANT_BOOL *pvarfVisible)

Visual Basic: Function GetVisible(control As IRibbonControl) As Boolean

So, you just need to return an appropriate boolean value whether to display controls or not.

The IRibbonUI.Invalidate or IRibbonUI.InvalidateControl methods can help you update the ribbon controls at runtime (get your callbacks invoked and get updated values).
