Populate Datagridview With MySQL Database using C#. Net

In this tutorial,  I will teach you how to populate data in the Datagridview using MySQL Database and C#.net. This tutorial will help you enhance your knowledge about displaying the data in the Datagridview. This method will display the data that has been saved in the database from the Datagridview. See the step by step guide below.

Let’s get started:

Steps How to Populate Datagridview With MySQL Database using C#

Step 1: Create a database in the MySQL database named “productdb“.

Step 2: Create a table using the following query below.

CREATE TABLE IF NOT EXISTS `tblproduct` (
 `PRODUCTID` int(11) NOT NULL AUTO_INCREMENT,
 `MODEL` varchar(30) NOT NULL,
 `BRAND` varchar(30) NOT NULL,
 `DESCRIPTION` varchar(99) NOT NULL,
 `PRICE` double NOT NULL,
 PRIMARY KEY (`PRODUCTID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;

Step 3: Insert the data using the following query below.

INSERT INTO `tblproduct` (`PRODUCTID`, `MODEL`, `BRAND`, `DESCRIPTION`, `PRICE`) VALUES
(1, 'HK-LE3212UVP', 'Sharp', 'LCD VIDEO-KARAOKE 32''''', 33298),
(2, 'HK-LE1110UVP', 'Sharp', 'LCD VIDEO-KARAOKE 19''''', 22198),
(3, '21V-FS720S', 'Sharp', 'Pure Flat TV ', 7190),
(4, 'ES-D708', 'Sharp', 'Spin Dryer 7kg ', 4998),
(5, 'ES-D958', 'Sharp', 'Spin Dryer 9.5 KG', 5698),
(6, 'SJ-DT55AS', 'Sharp', '5.4 CU.FT S/D SEMI AUTO ', 10900);

Step 4: Open Microsoft Visual Studio and create new windows form application.

Step 5: Design the Form as follows.

Step 6: Go to the solution explorer and hit the “view code” to fire the code editor.

Step 7: In the code editor, initialize all the MySQL classes that are needed.

Note: Add MySQL.Data.dll as your references to access mysql  and include “using MySql.Data.MySqlClient;”  above the namespace to access mysql library.

 //initialize sql connection
 MySqlConnection con = new MySqlConnection();
 //initialize all classes
 MySqlCommand cmd = new MySqlCommand();
 MySqlDataAdapter da = new MySqlDataAdapter();
 DataTable dt = new DataTable();

Step 8: Create a connection between MySQL and C#.net.

 private void Form1_Load(object sender, EventArgs e)
 {
 //set a connection string 
 con.ConnectionString = "server=localhost;user id=root;password=;Database=productdb;";
 }

Step 9: Go back to the Form Design, double-click the button and do the following code in the click events of a button.

 private void button1_Click(object sender, EventArgs e)
 {
 string query;
 try
 {
 con.Open();
 //create a query for retrieving data in the database.
 query = "SELECT * FROM `tblproduct`";
 //initialize new Sql commands
 cmd = new MySqlCommand();
 //hold the data to be executed.
 cmd.Connection = con;
 cmd.CommandText = query;
 //initialize new Sql data adapter
 da = new MySqlDataAdapter();
 //fetching query in the database.
 da.SelectCommand = cmd;
 //initialize new datatable
 dt = new DataTable();
 //refreshes the rows in specified range in the datasource. 
 da.Fill(dt);

 
 dataGridView1.DataSource = dt;
 
 }
 catch (Exception ex)
 {
 //catching error
 MessageBox.Show(ex.Message);
 }
 finally
 {
 da.Dispose();
 con.Close();
 }
 }
