TabItem Headerstyle gone after instantiation a TabItem from a file
posted
Hi - when I add a Tab to my xamribbon like this Dim StandardTab As New RibbonTabItemStandardTab.Header = "Standard RibbonTab works fine"myMainMenu.Tabs.Add(StandardTab) Xamribbon works as expected and the TabHeader inherits thestyle according to my Xamribbon Theme setting (Onyx) The problem occurs when I instantiate a tab from a alreadyexisting tabitem (I've written in a separate xaml file) andadd it to the xamribbon. Dim AdressesTab As New AdressenRibbonTabAdressesTab.Header = "problem tab from a xaml file"myMainMenu.Tabs.Add(AdressesTab) Now the TabHeader style one expects from Theme "onyx" isgone. 

Any help is welcome!

Maybe this could be a PEBTAC-Problem :-)

    In WPF, the key used for obtaining a local Style is always the type of the class (regardless of the DefaultStyleKey). So by deriving from RibbonTabItem, you are causing WPF to look for a local Style for your derived class - AdressenRibbonTab. Since there are no local styles with that as its TargetType, WPF doesn't find a local style and only ends up using the generic theme Style. So instead of defining a derived RibbonTabItem, you should just define a xaml file for the RibbonTabItem (i.e. create a xaml file, copy the contents of the current file you have and remove the x:Class - or just remove the x:Class and delete the backing .cs file) and then use Application.LoadComponent to create the RibbonTabItem instance.

    e.g.

    RibbonTabItem tab = Application.LoadComponent(new Uri("AdressenRibbonTab.xaml",UriKind.Relative )) as RibbonTabItem;
