Solution 2

C#

System.Windows.Forms.MessageBox.Show

is for Windows forms not web forms

You can instead display an alert using javascript alert like

C#

Response.Write("<script type='text/javascript'> alert('your message here.')</script>");

This is possible in web forms also,
try,
put namespace on starting using System.Windows.Forms; then
use Message.show("");

There is no direct suport for message box in asp.net. One alternative is you can use javascript to display an alert.

Here is asp.net we do not have direct message box like windows forms but have confirmatation box or alerts message or popups using javascripts
Simple MessageBox functionality in ASP.NET[^]
ASP.NET MessageBox[^]
ASP.Net Message Box Alert Display[^]
here is simple example using javascript:

XML

<html>
 <head>
 <script>
 function display_alert()
   {
   alert("Hello! I am an alert box!!");
   }
 </script>
 </head>
 <body>

<input type="button" onclick="display_alert()" value="Display alert box">

</body>
 </html>

hope it helped

Happy Coding!!
