title: ASP.NET how to disable button on submit?
body: <p>I have forms with payment in ASP.NET site, when user clicks on asp:Button sometime he submits few times. I want to disable this functionality without harming current ASP.NET site ( by that i mean no fancy jQuery, unless it is very basic and will not interfere with ASP.NET built-in validation)</p>
  
  <p>thanks!!!</p>
