What's the "proper" way to retrieve a reference to a ribbon object?
- by Nick
For a VSTO workbook project, is there a best practice for retrieving a reference to the Ribbon object from the ThisWorkbook class? 
Here's what I'm doing: In my Ribbon class, I created a public method called InvalidateControl(string controlID). I need to call that method from the ThisWorkbook class based on when a certain workbook level event fires. But the only way I can see to "get" a reference to that Ribbon object is to do this...
    // This is all in the ThisWorkbook class
    Ribbon ribbon;
    protected override IRibbonExtensibility CreateRibbonExtensibilityObject()
    {
        this.ribbon = new Ribbon();
        return this.ribbon;
    }
...which seems a little smelly. I mean, I have to override CreateRibbonExtensibilityObject() regardless; all I'm doing beyond that is maintaining a local reference to the ribbon so I can call methods against it. But it doesn't feel right. Is there another, better way to get that reference in the ThisWorkbook class? Or is this pretty acceptable?
Thanks!
