Nup, using messagebox.show in Asp.net is a bad idea. you can use javascript to do the same.

If you want to show messagebox from code behind then you can use ScriptManager Class[^] to register javascript with page. Try this

C#

ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "Myscript1", @"alert('Hi am a alert box');", true);

Problem

Message Box is for Windows Forms. You can still use it, but that will not reflect at client side.

Solution

So, you need to use javaScript alert or confirm box.

Alert Box from Code Behind
Re: MessageBox.Show in ASP.Net[^]
Confirm Box from Code Behind
Confirmation box from server side in asp.net[^]

Simplest way:

C#

Response.Write("<script type='text/javascript'>");
Response.Write("alert('There does not exist any simpler alert then this.');");
Response.Write("</script>");
