Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

There is no "problem" to solve. Where do you think server side code is going to display a MessageBox? You need to use client side code.

Hi prakashmondal, you cannot show a MessageBox in an ASP.NET environment because the result of ASPNET is HTML and Javascript. Imagine that you have a client that connect from Linux, Linux cannot install .NET Framework so the MessageBox's class doesn't exists there.

C#

string script = "alert('Registration Successfully Completed!');";
ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", script, true);

Hope it helps.
