If you define two UserControls in a project and you add two RadTabControls - one RadTabControl per UserControl, then in design-time you can only change the selection of one of the tab components.
Hi all,
After further investigation it appeared the issue is caused by VisualStudio designer and we logged bug report in the Microsoft Developer Community portal:
Will update the status to Won't Fix for the moment, however as soon as we have more information from MS will share it here and update the status if needed.
