BUG: CommandbarPopup.Caption changes CommandbarPopup.CommandBar.Name and viceversa.

Introduction

A CommandBarPopup has a Caption property and it has a CommandBar property, which returns the internal CommandBar associated to the CommandBarPopup. In turn, this CommandBar object has a Name property. These two properties (CommandBarPopup.Caption and CommandBarPopup.CommandBar.Name) are independent and serve different purposes: the Caption is shown in the user interface and the Name is used to identify the CommandBar. However, in VS 2010 and 2012 changing the Caption property changes the CommandBar.Name property and viceversa. This didn't happen in Visual Studio 2005/2008; it is a bug introduced when VS 2010 migrated from Office-based commandbars to WPF-based commandbars.

More information

Steps to reproduce the problem:

  • Create a VB.NET add-in with the code below.
  • The add-in creates a CommandbarPopup and shows the CommandbarPopup.Caption and CommandbarPopup.CommandBar.Name values after creating it, after changing the CommandbarPopup.Caption property and after changing the CommandbarPopup.CommandBar.Name values.
