This tutorial will teach you on how to load a data from a single column of MySQL to ComboBox object in your form. Loading a data to Textfield is different in loading a data to ComboBox. The process is the same but the code is different. Please follow all the steps to complete this tutorial.
Loading data from MySQL to ComboBox Steps
- Add a “ComboBox” item from your toolbox. It should look like the image below.
2. DoubleClick your form to generate a “form load event”. If already generated, you can access directly the load event code statement. It should look like the codes below.
- Private Sub LoadComboBox_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
- End Sub
3. Insert the following codes below for loading data from MySQL to your ComboBox.
- Str = "select * from TableName"
- Dim da As New MySqlDataAdapter(Str, conn)
- Dim dt As New DataTable("TableName")
- If dt.Rows.Count > 0 Then
- ComboBox1.DataSource = dt
- ComboBox1.DisplayMember = "Address"
- ComboBox1.ValueMember = ""
- End If
- Catch ex As Exception
- End Try
TableName – The table you want to load from MySQL
ComboBox1 – The name of your ComboBox
Address – Column name you want to load in ComboBox
