Add Buttons at Runtime - Visual Basic .NET

Tags: VB.NET, VB 2008, VB 2010, VB 2012, VB 2013

This is a tutorial on how to add a button at runtime in Visual Basic .NET

In this tutorial I will add two buttons to the form at runtime, on button will be used as a save button, the other is a cancel button

First add the following declarations below your Public Class Form1 line:

Dim btn1 As New System.Windows.Forms.Button
Dim btn2 As New System.Windows.Forms.Button

Add an event handler that will handle the click event of the button.

Private Sub Button_Click(ByVal sender As Object, ByVal e As EventArgs)
        'Add your code here such as: 
        If = "SaveButton" Then
            'save code here
        ElseIf = "CancelButton" Then
            'cancel code here
        End If
    End Sub

Then add the following code to any event that will be used to add the button at runtime. In this example I use the form load event to add the button.

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        btn1.Text = "Save"
        btn1.Name = "SaveButton"
        btn1.BackColor = Color.Green 'Change this to any color
        btn1.Location = New Point(45, 45) 'This is the position of the button on the form
        btn1.Size = New Size(75, 23) 'This is the size of the form
        AddHandler btn1.Click, AddressOf Button_Click

        btn2.Text = "Cancel"
        btn2.Name = "CancelButton"
        btn2.BackColor = Color.Red
        btn2.Location = New Point(125, 45) 'This is the position of the button on the form
        btn2.Size = New Size(75, 23) 'This is the size of the form
        AddHandler btn2.Click, AddressOf Button_Click
End Sub

When you load the form, the two button will be created, one you click any of them, the click event handler will be triggered.
