I want to add dynamic image button on site without ID of Image button so I am using ASP tag to generate dynamic controls with ParseControl method, It's working but event is not fired when click on Image Button
Default.aspx.cs Code
protected void Page_Load(object sender, EventArgs e)
{
string str = @"<asp:ImageButton runat=server ImageUrl=""~/close-icon (1).png"" OnClick=""click"" />";
Control c = Page.ParseControl(str);
form1.Controls.Add(c);
}
protected void click(object sender, ImageClickEventArgs e)
{
Response.Write("Image Clicl");
}
Default.aspx Code
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>

I found my answer, answer is below
Default.aspx.cs Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class dynamicimage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string str = @"<asp:ImageButton ID=""dynoimage"" ImageUrl=""~/images/about01.jpg"" runat=""server"" oncommand=""clickme"" commandname=""btn"" />";
Control c = ParseControl(str);
form1.Controls.Add(c);
((ImageButton)Page.FindControl("dynoimage")).Command += new CommandEventHandler(clickme);
}
protected void clickme(object sender,CommandEventArgs e)
{
Response.Write("Image clicked");
Label1.Text = "Image clicked";
}
}
and here is the Default.aspx page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="dynamicimage.aspx.cs" Inherits="dynamicimage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
<p>
<asp:Label ID="Label1" runat="server" Text="before click"></asp:Label>
</p>
</form>
</body>
</html>
