We can validate and save data in database using jQuery,
Ajax and Web-service method. jQuery
ajax allows us to call server side ASP.NET page
methods/functions declared as Web Method from client side without any postback.
We make ajax call to web method using jQuery which contains the code to insert
data in sql server.
In this article I am going to explain how to
validate and save data into SQL SERVER database table in
asp.net without any post back
(asynchronously) using jQuery AJAX JSON and WebMethod.
Description:
Implementation: Let’s create a sample page to demonstrate the concept.
Create a datanbase in sql server eg. “test”. Now create a table as given below:
CREATE TABLE [dbo].[Emp_Personal](
[EmpPer_Id] [int] IDENTITY(1,1) NOT NULL,
[EmpName] [varchar](100) NULL,
[Age] [int] NULL,
[Address] [varchar](500) NULL
) ON
[PRIMARY]
In
Web.config file create the connection string as:
<connectionStrings>
<add name="EmpCon" connectionString="Data Source=localhost;Initial Catalog=test;Integrated
Security=True"/>
</connectionStrings>
Now create a stored procedure to save Employee Personal Details
Create PROCEDURE [dbo].[SaveEmp_SP]
@EmpName VARCHAR(100),
@age INT,
@Address VARCHAR(500)
AS
BEGIN
INSERT
INTO dbo.Emp_Personal(EmpName,Age,Address)
VALUES(@EmpName,@age,@Address)
END
