We have a existing project that uses some older telerik libraries.
This application uses the RadRibbonView inside of an ElementHost control. It works great with the older telerik libraries.
I upgraded to the latest 2015 Q3 binaries and I am having problems.
The ribbon no longer displays in the element host.
I did some sanity checks by putting other telerik components into the element host, and they display fine.
Attached is a simple project that reproduces the issue.
Basically it creates a usercontrol.
Adds a simple ribbonview
Adds this ribbon view to a win forms control via element host.
