I am writing this article on demand as I got a request from one of my friends. He told me that he is looking for this requirement so I created this. As per his requirement, he needs to show data from SQL Server database table in ASP.NET GridView using jQuery, JSON and AJAX call.

Below is my Data Table from which I am showing data.

  1. CREATE TABLE [dbo].[Customers](
  2. [CustomerID] [int] IDENTITY(1,1)NOTNULL,
  3. [Name] [varchar](50)NULL,

  5. [City] [varchar](50)NULL,
  6. CONSTRAINT [PK_Customer] PRIMARYKEYCLUSTERED
  7. (
  8. [CustomerID] ASC
