When i try to add a RadRibbonTab at runtime with the binaries noxaml, the RadRibbonTab is well added in the Items collection but not rendered.
You can found a sample project here
They are two projects one with normal binaries and one with noxaml binaries. When i click on button "Add new tab" when using no-xaml nothing happend, when i use the normal binaries it's working.
Is it a problem with the implicit theme ?
