·         Introduction

In this article we will learn how to insert, edit, update and cancel the records in a GridView using a single stored procedure. Here we use a Template Field inside a grid view control. Inside theTemplate Field we place an Item Template for displaying records from the
 database at runtime. Other templates used here are EditItemTemplate and Footer Template. Here, paging facilities are also provided.

Stored Procedure
·         CREATE PROCEDURE [dbo].[employee_pro]
·         (
·         @empid as int=0,
·         @name as varchar(50)='',
·         @address as varchar(50)='',
·         @designation as varchar(50)='',
·         @status as varchar(50)=''
·         )
·         AS
·         BEGIN
·          
·         SET NOCOUNT ON;
·         if(@status = 'Display')
·         begin
·         Select * from employee
·         end
·         else if(@status = 'Add')
·         begin
·         Insert into employee(name,address,designation,createtime) values(@name,@address,@designation,getdate())
·          
·         end
·         else if(@status = 'Update')
·         begin
·         Update employee set name=@name, address=@address,designation=@designation whereempid=@empid
·          
·         end
·         else if(@status = 'Delete')
·         begin
·         Delete from employee where empid=@empid
·         end
·         END

Now let's move to the coding part.
