Hi Telerik Support,
Here is a description of the environment I work with:
- Visual Studio 2019 (version 16.9.3)
- NuGet package is UI.For.Winforms.AllControls.Net50 (v2021.1.326)
- Project is a .NET5.0 class library.
When trying to add a RadDropDownListElement to a RadRibbonBarGroup, Visual Studio seems to encounter an error and a window pops up with the message "The connection to the server has been lost". Adding other types of elements to the RadRibbonBarGroup seems to work properly (I managed to add buttons without any issues).
I will attach a screenshot of the issue.
Thanks for your help !
