You can use our libraries from any managed language including managed C++.
We only ship samples in C# and VB, but will work with you to try to get you going using our libraries with MCPP is that is what you need to do. Here is one sample that you may find useful. If you get stuck doing something, submit a Direct Trac support incident, and we will try to be of help.
Now you will not be able to just swap out the stingray libraries with the syncfusion libraries. Both grids have some similar concepts, but they are very different grids codewise. They do not have the same function signatures, so I suspect you will have to rewrite a lot of code. And, it may be much easier to do in C#.
