RibbonWindow (HeaderItemsSource)

[Matthias Wieland]

Hello, 

I'm currently experimenting with Window Ribbon. I've encountered a problem: as soon as I try to set a HeaderItemsSource and start the application, it throws an error.

I have also tried the other examples, but it's always the same issue.

Version: 28.2.9

Hi Matthias Wieland,

We have tested the reported issue on our end and were able to reproduce it only when no Ribbon control is assigned or initialized in the Loaded event in code-behind. However, when the Ribbon is initialized in XAML, we did not encounter the issue.

Could you please confirm whether your implementation matches our test scenario? If not, kindly provide additional code snippets showing how you are initializing the Ribbon on your end so we can further analyze the issue.

Looking forward to your response.

Hello,

thanks for the quick response. I just tested it, and it works! I'm using the RibbonWindow as the default window because Windows docking, etc., works very well here—better than with the ChromelessWindow.

The tab bar is hidden for me. 

Thanks!

Hi Matthias Wieland,

Thank you for your confirmation!

We're glad to hear that initializing the Ribbon in XAML resolved the issue for you.
