You are right that the two components are pretty similar. Please note that the ApplicationMenu
was developed/designed with the already obsolete and deleted RadRibbonBar
control. It was designed in consistency with the Microsoft Office 2003 and 2007 themes. With the RadRibbonView
control came the Backstage
component which is consistent with the design of the Microsoft Office 2010 theme.
However, there are slight differences between those components. Most visible is that the Backstage
is opened all over the available space, while the ApplicationMenu
takes as much as it needs. Also, the ApplicationMenu
which is not available in the Backstage
. Furthermore, when SplitButtons
are hosted in the ApplicationMenu
you can open their content when you hover the button part. When they are hosted in the Backstage
you have to click on the button to open the DropDownConten
Basically, you are allowed to use the most convenient component in your case.
