Retrieving Data Using DateTimePicker in VB.Net

Submitted by janobe on Friday, February 15, 2019 - 11:19.

In this tutorial, I will teach you how to retrieve data using datetimepicker in vb.net. This method has the ability to filter the data in a specific date by using the datetimepicker. In this way, you will be able to find out how many records will appear in the date that you have selected. See the procedure below.

Creating Database

Create a database named “profile” Do the following query to create a table and add the data inside the table.

CREATE TABLE `profile` (
  `id` int(100) NOT NULL,
  `name` varchar(100) DEFAULT NULL,
  `email` varchar(100) DEFAULT NULL,
  `photo` varchar(250) DEFAULT NULL,
  `joindate` date NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
 
--
-- Dumping data for table `profile`
--
 
INSERT INTO `profile` (`id`, `name`, `email`, `photo`, `joindate`) VALUES
(1, 'Jaison Joy', 'joydfdfd33322@mail.com', 'http://jaisonjoy.com//image/man.png', '2019-01-01'),
(2, 'Vini', 'vini232ew@gmail.com', 'http://jaisonjoy.com/image/female.png', '2019-01-15'),
(3, 'John', 'johnsde34223@gmail.com', 'http://jaisonjoy.com/image/male.png', '2019-02-03'),
(4, 'Test', 'Test', NULL, '2019-02-14'),
(5, 'test2', 'Test2', NULL, '2019-02-14');

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application in visual basic. ps1

Step 2

Do the form just like shown below. ps2

Step 3

Go to the code view and add a namespace for mysql above the class.

Imports MySql.Data.MySqlClient

Step 4

Inside the class, create a connection between MySQL and Visual Basic 2015. After that, declare all the classes that are needed.

    Dim con As MySqlConnection = New MySqlConnection("server=localhost;user id=root;password=;database=profile;sslMode=none")
    Dim cmd As MySqlCommand
    Dim da As MySqlDataAdapter
    Dim dt As DataTable
    Dim sql As String

Step 5

Create a function for retrieving data in the database

    Dim con As MySqlConnection = New MySqlConnection("server=localhost;user id=root;password=;database=profile;sslMode=none")
    Dim cmd As MySqlCommand
    Dim da As MySqlDataAdapter
    Dim dt As DataTable
    Dim sql As String

Step 6

Do the following codes for retrieving all the data in the database that will be display inside the datagridview in the first load of the form.

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        sql = "SELECT * FROM `profile`"
        DataGridView1.DataSource = findData(sql)
    End Sub

Step 7

Write this code for filtering all the data that will be display inside the datagridview when the date is changed.

    Private Sub DateTimePicker1_ValueChanged(sender As Object, e As EventArgs) Handles DateTimePicker1.ValueChanged
        Dim todates As String
        todates = Format(DateTimePicker1.Value, "yyyy-MM-dd")
 
        sql = "SELECT * FROM `profile` WHERE DATE(joindate) = '" & todates & "'"
        DataGridView1.DataSource = findData(sql)
    End Sub
