Bug: RadComboBox bugs the Visual Studio 2019 UI

[Martin]

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?

Your Designer looks like its closed ?

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
