Implicit Themes 'Resource Not Found' warning

[Niko]

Hello,

I just upgraded my WPF solution to the latest Telerik version, 2014.1.224.40. Whenever switching implicit themes I see hundreds of these errors: 

System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='Telerik.Windows.Controls.InternalResourceKey'; ResourceKey.HashCode='0'; ResourceKey.Type='Telerik.Windows.Controls.InternalResourceKey'

Also, sometimes when switching themes the application freezes. I'm thinking it's related to the hundreds, if not thousands, of these errors showing in the output window.

I saw this was noted as fixed in the version notes of 2014.1.224.40, yet I am still seeing it. Any ideas?

Thanks,
Niko

Hello Niko,

I reviewed our source and find several issues that may cause your problems. The fix will be included in our next latest internal build on Monday.

However to be sure that we are speaking about the same thing, please try to build your application without merging the resources for GridView and RibbonView and let me know whether this clears the warnings that appear.

Hello Sia, thanks for your response.

I removed the GridView and RibbonView resources from my application, and the warnings still appear. Through trial and error, I removed each Telerik resource one by one to see which was causing the warnings. All warnings seem to trace back to the Telerik.Windows.Controls resource, which makes sense since the warning specifically calls out this resource: "ResourceKey='Telerik.Windows.Controls.InternalResourceKey'".

I also tried upgrading to the latest internal build, and still no luck. Any help would be appreciated.

Thanks,
Niko

Hello Niko,

Thank you for the provided information. What comes to my mind is that maybe you merge the ResourceDictionaries on UserControl level but currently we support only merging them on application level - in the App.xaml. This is needed for the themes that support dynamic resources such as Windows8, Windows8Touch and Office2013. We plan to introduce support of merging them on UserControl level with one of our upcoming versions. Please let me know whether this helps. If not - a small runnable application reproducing your issue would be appreciated.

Has this issue since been resolved? I am interested.

Hi Keith,

The problem has been solved and you may test it with a recent version of UI for WPF. 
I'm attaching you small sample demo, which you can use for testing purposes.
