Design view is destroyed after switching between Default (English) and Polish languages

There is a big problem with Telerik controls when using national resource files.  Switching from one language to another and again sometimes destroys the user interface. It especially concerns RadCheckBox control. Text, tooltip and probably other properties from one control appear in other control etc. I think it can be a general problem because I also noticed that sometimes Image from one RadButton control appears in other button.

I prepared a set of images which show how it happended in my case. Switching from Default language to Polish language and again and then adding and removing new RadCheckBox completly destroyed user interface in my sample UserControl. This new RadCheckbox was created as a copy of existing RadCheckBox what may be a clue.

I also attached VS2019 project with my sample UserControl.

 

Best regards,

Andrzej

This problem is critical for me. I had to suspend development of our new product, because I'm not able to design complex forms that have a few language versions.

Hello, Andrzej,

Thank you for providing a project that replicates the issue. I was also able to observe a broken design view when changing the language of the user control. At this moment, I am not able to suggest a workaround to prevent this behavior.

I converted this ticket into a bug report so our developers can fix it. You can see it in our feedback portal here: Design view is destroyed after switching between Default (English) and Polish languages

I updated your Telerik Points for this report.
