How to build a spreadsheet-like control in WPF?

Is there a good resource (online or books) to learn how to build back-end systems and version control?

• I am a front-end developer and never really had to work on a back-end system.  I feel disconnected all the time since I don't know how version control works and how to build admin sections to ban users, manage other things.  I think it's helpful if I give an example. Let's say I want to build a social network -- I can take care of the front stuff but now how do I go about saving different versions of the website and how to make sure it's easy to push the new code and any old code at will and other best practices?

• Answer:

  For version control, I highly recommend you learn For your back-end you could use multiple languages and I don't want to get into that. However, I recommend that you look into the advantages of Python, Rails and PHP to see what suits you best. People argue a lot about but frankly, you can achieve the same with either. You have to choose what you like. You can build separate sections of your application for different users using a concept known as Access Control Lists. Using a framework in any language I mentioned should have an Access Control List system.
