I can't see any RequiredFieldValidator in your posted code.

The code written in the function Confirm() is executed before Button1_Click().
Do you get validation message when you remove Confirm() ?

I think you want to show the message box after required field validater validates the input.
Call the Confirm() function from onsibmit of the form instaed of calling it from onClientClick.
Do a little change in your code as below;

ASP.NET

<form id="form1" runat="server" onsubmit="Confirm()><br mode=" hold=" /></form></pre><br mode="></form>
