How to Bind,Insert,Edit,Update,Delete in GridView in asp.net VB.Net

Introduction: In this article you will learn the following using Asp.Net with VB.Net Language. You can also read the same article in Asp.Net with C# language on Bind,Save,Edit,Update,Cancel,Delete,Paging example in GridView in asp.net C#
  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 Database table to GridView Data Control? 
  3. How to Edit, Update and Delete in GridView? 
  4. How to Fill Day, Month and Year in DropDownList control 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?

Implementation: Let's create an asp.net application to see it in action.
  • First You need to 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 Initial Catalog as per your application.
  • Create a folder in the root directory and name it "Images" to store the edit and delete images used in gridview. Search edit and delete .png icon image from the google search and add to 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.
