In most of the cases developers need to add dynamic controls in asp.net application using code behind or runtime. Here in this article i will explain how one can add dynamic Asp.Net Server side Button in runtime and assign or handle click event in asp.net using C# and VB.NET.

To add a asp.net server side button control when page is loaded. We need to write the below code segment under page_Load Event:

C#.Net:

view source

print?

01	protected void Page_Load(object sender, EventArgs e)

02

{

03	Button cmd = new Button();

04	cmd.Text = "Click Me";

05	this.form1.Controls.Add(cmd);

06	cmd.Click += new EventHandler(Dynamic_Method);

07

}

08

09	protected void Dynamic_Method(object sender, EventArgs e)

10

{

11	Response.Write("You have clicked at: "+DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss tt"));

12

}

VB.Net:

view source

print?

01	Private Sub Dynamic_Method(ByVal sender As System.Object, ByVal e As System.EventArgs)

02	Response.Write("You have clicked at: " + DateTime.Now)

03

End Sub

04

05	Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

06	Dim cmd As New Button

07	cmd.ID = "BOTON"

08	cmd.Text = "Click Me"

09	AddHandler cmd.Click, AddressOf Dynamic_Method

10	Form.Controls.Add(cmd)

11

End Sub
