Hello again Dan,
There are no particular incompatibilities between both products, it's just they are meant to follow different programming concepts and project infrastructure.
Though we don't recommend mixing them, in theory you can use both technologies into one ASP.NET project, as described in the following online articles:
As for Kendo UI
is powered by it, and additionally includes MVC server wrappers for easy server-side programming. Therefore, if you are used to server coding in C# and feel more comfortable with it, UI for ASP.NET MVC might be the better option for you.
I hope this explanation makes sense.
Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
