In this example I will show you how to bind data in asp.net vb gridview using JQuery. I created EmployeeDetails class with table column as properties. On the pageload ajax function will call a request to webmethod and return the json array list. I used Html table structure to populate data to gridview.
We will be using employee table
Step 1: Create a table using the following script with data:
CREATE TABLE[dbo].[Employee](
[EmployeeID] [int] IDENTITY(1,1) NOT NULL,
[Name] [nvarchar](50) NULL,
[Gender] [nvarchar](50) NULL,
[City] [nvarchar](50) NULL,
CONSTRAINT[PK_tbl_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON[PRIMARY]
SET IDENTITY_INSERT[dbo].[Employee] ON
INSERT [dbo].[Employee] ([EmployeeID], [Name], [Gender], [City]) VALUES (1, N'Mark', N'Male', N'Berlin')
INSERT [dbo].[Employee] ([EmployeeID], [Name], [Gender], [City]) VALUES (2, N'John', N'Male', N'Beijing')
INSERT [dbo].[Employee] ([EmployeeID], [Name], [Gender], [City]) VALUES (3, N'Mary', N'Femal', N'Brussels')
INSERT [dbo].[Employee] ([EmployeeID], [Name], [Gender], [City]) VALUES (4, N'Steve', N'Male', N'Luxembourg')
INSERT [dbo].[Employee] ([EmployeeID], [Name], [Gender], [City]) VALUES (5, N'Ben', N'Male', N'Pyongsong')
SET IDENTITY_INSERT[dbo].[Employee] OFF
Step 2: Copy and paste the following code.
