While editing the XAML document, I'm experiencing weird behavior in VS2019. 

All examples applies when the Design editor is active together with XAML editor.

Example 1:

Selecting XAML with mouse stops when i start selecting the telerik:RadComboBox 

Example 2:

Copy Pasting bugs out, either the selection is empty or incorrect !

Example 3:

'Forcus' in Visual Studio is sometimes overtaken by the RadComboBox which is very annoying.

Hello Martin,
Would you find it possible to demonstrate the behavior you observe in a small sample project so that I can further investigate at my end?
I tested this, but the behavior I observe is expected:

I came across the following thread where my colleague proposed a possible solution for a similar scenario. Can you please give it a try and let me know if it works for you?

I think the problem was related to Databinding and the fact that the control constructor sets the DataContext to a very big ViewModel.

After refactoring the project and separating the control along with a different approach to bindings, the performance of the whole project and especially the RadComboBox'es are MUCH better.

The problem is gone now .. hmm

Please excuse me for overlooking this - indeed, when opening both the designer and code views I was able to replicate the issues you described. Thus, I've logged the following bug report in our feedback portal on your behalf to which you can subscribe. As a thank you for bringing this to our attention, I've awarded you with some Telerik points.

Nonetheless, I'm happy to hear that the issue is now resolved at your end. If I can further assist you with anything else, please let me know.

No answers yet. Maybe you can help?
