merged dictionary

[robert]

Hello Telerik Team,
i have a user control Project. I declared the theme files in MergedDictionaries to style the ganttcontrol.
The structure is designed as Mvvm. When i start the Application i get a Null reference exception.
How can i fix this issue? Thank you and regards Robert ...

Hello Robert,

I don't see anything incorrect in the way you have merged the ResourceDictionaries, I have also tested it and it work as expected. Please make sure you have the correct paths to the XAML files as this might cause the issue. However the exception might be caused by something else, not the merged dictionaries, if so we would need more sample code or a sample project if possible.

I'm looking forward to hearing from you.
