In this short code snippet article I will explain how to create Dynamic Button controls at runtime and also attach Click event handler to the dynamically created buttons
C#
//Counter for Dynamic Buttons.
int DynamicButtonCount = 1;
 
//This event generates Dynamic Buttons.
private void btnGenerate_Click(object sender, EventArgs e)
{
    string name = "Dynamic Button_" + DynamicButtonCount;
    Button btnDynamicButton = new Button();
    btnDynamicButton.Name = name;
    btnDynamicButton.Text = name;
    btnDynamicButton.Size = new System.Drawing.Size(200, 30);
    btnDynamicButton.Location = new System.Drawing.Point(40, DynamicButtonCount * 40);
    btnDynamicButton.Click += new EventHandler(this.btnDynamicButton_Click);
    Controls.Add(btnDynamicButton);
    DynamicButtonCount++;
}
 
//This event is triggered when a Dynamic Button is clicked.
protected void btnDynamicButton_Click(object sender, EventArgs e)
{
    Button dynamicButton = (sender as Button);
    MessageBox.Show("You clicked. " + dynamicButton.Name);
}
 
 
VB.Net
'Counter for Dynamic Buttons.
Dim DynamicButtonCount As Integer = 1
 
'This event generates Dynamic Buttons.
Private Sub btnGenerate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnGenerate.Click
    Dim name As String = ("Dynamic Button_" & DynamicButtonCount)
    Dim btnDynamicButton As Button = New Button
    btnDynamicButton.Name = name
    btnDynamicButton.Text = name
    btnDynamicButton.Size = New System.Drawing.Size(200, 30)
    btnDynamicButton.Location = New System.Drawing.Point(40, (DynamicButtonCount * 40))
    AddHandler btnDynamicButton.Click, AddressOf Me.btnDynamicButton_Click
    Controls.Add(btnDynamicButton)
    DynamicButtonCount = (DynamicButtonCount + 1)
End Sub
 
'This event is triggered when a Dynamic Button is clicked.
Protected Sub btnDynamicButton_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim dynamicButton As Button = CType(sender, Button)
    MessageBox.Show(("You clicked. " + dynamicButton.Name))
End Sub
