Add Details of an Employee With Image and Display it Into a Gridview

In this article, we will learn how to add details of an employee with an image and display it in a GridView. Here an image will be stored in the application folder. We can also edit, update, delete, and cancel the details of the employee in the GridView.

Table Creation

Stored procedure

CREATE PROCEDURE insert_employee  
    (  
        @name varchar(50),  
        @address varchar(50),  
        @image varchar(50)  
    )  
AS  
Insert into employee values(@name, @address, @image)  

CREATE PROCEDURE update_employee  
    (  
        @id int,  
        @name varchar(50),  
        @address varchar(50)  
    )  
AS  
Update employee set name = @name, address = @address where id = @id  

CREATE PROCEDURE delete_employee  
    (@id int)  
AS  
Delete from employee where id = @id

Plz tell me how to add connection string on Default.aspx.cs Code..???
antony victor13y ago
thanks for detailed explaination.. I have a doubt sir, assume the sample code above is a category page (with name and image) how can i create a subcategory page with a dropdownlist so that category name provided in previous page can populate in it and below that same subcategoryname and image can be added and displayed in gridview..
antony victor13y ago
thanks. but i have a doubt sir, the actual image is saving in database. so the size of the database increases with it. can we add the path only and store the images in server?
