Bind,Save,Edit,Update,Cancel,Delete,Paging example in GridView in asp.net C#


IntroductionIn this article I am going to explain How to perform CRUD operation i.e. Bind, Insert/Save, Edit, Update, Cancel, Delete, Paging in GridView in asp.net using C# language.
    Basically you will learn the following through this example:
    1. How to Save/Insert and update data in Sql Server Database from asp.net web application? 
    2. How to Bind Data from Sql Server to GridView Data Control? 
    3. How to perform Edit, Update and Delete operation in GridView? 
    4. How to Fill Day, Month and Year in DropDownList and set current date as selected? 
    5. How to find controls like TextBox and DropDownList placed inside GridView and get their values? 
    6. How to implement paging in GridView?
    In previous articles I explained How to Bind,Insert,Edit,Update,Delete in GridView in asp.net VB.Net and WCF Service to bind,insert,edit,update,delete from sql server database and Upload,download,delete image files from the GridView and Bind, edit, update and delete data in Repeater  & DataList  and Export GridView data to PDF file and Load more records from database in gridview on button click and  Upload and store image in binary format in database and bind to Gridview

    Implementation: Let's create an example web application to see it in action.

    • First of all create the Database in Sql Server and Name it "Emp_DB" or whatever you want. Create a Table having columns as shown in figure and name it "Emp_Tb" .
    Note: Emp_Id_Pk column is set to Primary key and Identity specification is set to yes with Identity increment and Identity seed equal to 1.
    • In the Web.config file create the connection string as:
    <connectionStrings>
                                    <add name="conStr" connectionString="Data Source=LocalServer;Initial Catalog=Emp_DB;Integrated Security=True"/>
                    </connectionStrings>

    Note: Replace the Data Source and the Initial catalog as per your application.

    • Create a folder in the root directory and name it "Images". Search edit and delete .png icon image from the google search and add in the "Images" folder. 
    • Now In the Design page(.aspx) design the web page as:
    Note: I have also implemented the asp.net validations on the Employee Name, Address and the Salary fields.

    Hello kamal...I think you try to bind data to gridview using sqldatasource from design side as well as using c# code from code behind side..

    You need to chose one way to bind the grid
    if binding using code behind i.e using code then remove the datasourceid property from grid view

    Thankyou you for your help i have removed the sqldatasource from the property of grid view and now it is working .

    Their is another problem that when i insert a data from asp.net page to sql server . The grid view does not get updated i have to refresh the page thern the inserted date gets displayed on the grid view.
