Hi F Sccheltens,
Thanks for your post.
I did a test in my side using VS2015 Express and it works well in my side. I can resize rows and columns successfully.
Please edit rows and columns:

Please create a new windows form application and follow the steps in the document below then try it again:

By the way, I suggest you could try to use VS2015 Community, it's a free version with full featured.
Best Regards,
