asp.net using c# or vb.net.

In previous posts I explained how to create controls dynamically in asp.net and save dynamic control values in database and many articles relating to Asp.net, JQuery, and SQL etc. Now I will explain how to handle dynamic button click events in asp.net using c# or vb.net for that first we need to write the following code in your aspx page
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Create controls dynamically in asp.net and handle button
click events</title>
</head>
<body>
<form id="form2"
runat="server">
<div>
<asp:Panel ID="pnlInfo"
runat="server">
</asp:Panel>
</div>
</form>
</body>
</html>
|
After completion of aspx page design add the
following namespaces in code behind
C# Code
using System;
using
System.Web.UI.WebControls;
|
After add namespaces write the following code
in code behind like as shown below
protected void Page_Load(object sender, EventArgs
e)
{
Button btnSubmit = new Button();
btnSubmit.ID = "btnSubmit";
btnSubmit.Text = "Submit";
btnSubmit.Click += new
System.EventHandler(btnSubmit_click);
pnlInfo.Controls.Add(btnSubmit);
}
// Dynamic button click event
protected void btnSubmit_click(object sender, EventArgs
e)
{
Response.Write("you
clicked on button");
}
|
VB.NET Code
Imports System.Web.UI.WebControls
Partial Class Default3
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles
Me.Load
Dim btnSubmit As New Button()
btnSubmit.ID = "btnSubmit"
btnSubmit.Text = "Submit"
AddHandler btnSubmit.Click, AddressOf
btnSubmit_click
pnlInfo.Controls.Add(btnSubmit)
End Sub
' Dynamic button click event
Protected Sub btnSubmit_click(ByVal sender As Object, ByVal e As EventArgs)
Response.Write("you
clicked on button")
End Sub
End Class
