Dynamically adding AppBar buttons to a RadWindow

[Damian]

I am trying to dynamically add buttons to a RadWindow AppBar and they are not being updated in the UI.

My code looks like this:

var appBarButton = (ApplicationBarButton)Resources["LoginAppBarButton"];
if (appBarButton == null) return;
LoginRadWindow.ApplicationBarInfo.Buttons.Add(appBarButton);

Where I have a resource set for the ApplicationBarButton ("LoginAppBarButton") and the LoginRadWindow is the RadWindow control.

The above code runs fine and I get the button added to the collection however this is not reflected on the UI so the button doesn't actually appear.

Is there a way to dynamically add AppBarButtons to the RadWindow AppBar?

Hi Damian,

Thanks for writing.

Are you adding the buttons while the Window is already opened? If yes - that will not work. You should add the buttons before opening the Window to make sure they are displayed.
