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 the Template 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.
Table Structure
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 where empid=@empid
end
else if(@status = 'Delete')
begin
Delete from employee where empid=@empid
end
END
Now let's move to the coding part.
