DYNAMIC BUTTON CLICK EVENT

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:

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:

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
