It was working great but client asked me to use the jsGrid instead of Web Grid as it has many ready to use features like (Edit, Delete, Search, etc..).  Initially, jsGrid gave me very hard time to display the data in it but after few hit and trial I manage to display the data. After spending couple of hours on jsGrid, I started liking it. In this article, I am going to explain how to use the jsGrid to display the data and some other tactics in very easy steps. I am building the application in ASP.NET MVC. Step 1.
