Visual Studio LightSwitch is a new tool for building data-driven Silverlight Application using Visual Studio IDE. It automatically generates the User Interface for a DataSource without writing any code. You can write a small amount of code also to meet your requirement.

In my previous chapter “Beginners Guide to Visual Studio LightSwitch (Part – 4)” I guided you step-by-step process to create a List and Details screen. There I demonstrated you, how to integrate two or more tables inside a single screen.

In this chapter, I am going to demonstrate you of doing custom validation using Visual Studio LightSwitch. This time we will jump into writing some code to extend the functionalities.

Today morning I received the great news that, I have been awarded as CodeProject Most Valuable Professional (MVP). It's definitely a great achievement for me.

Last year I wrote 32 articles, added 37 small blog articles, 8 Tips & Tricks in CodeProject; also I answered some queries in Technical forums. I was an active GIT forum member too. All this effort gave me the fruit. Last year, received the Microsoft MVP award for Silverlight and this year from CodeProject. Wuhu!!!
