A number of people have asked about binding the ItemsSource of a TabGroupPane to their collection. This is not supported by the TabGroupPane so I thought I would explain why and provide an alternative approach. If you’re looking to bind the DocumentContentHost or even a specific SplitPane to a collection, you should still read on as this solution will allow for that as well.

There are a couple of Style related issues that I see often. The first is a case where you have set our Theme property but some of the elements do not appear to be following the look for that theme.

I think most developers and end users have come to expect that when a menu item or button is disabled that the image and text within that item are displayed as grayed out. This provides a visual indication that the item is not available for use.
