title: How to show an ASP.NET validation message next to my Save button as well as next to the validated control?
body: <p>I'm using asp CustomValidator to perform client-side validation on a few controls when the user clicks the Save button on a page. However, this page is quite long so often they can't see the validation message that's displayed next to a control that fails validation. How can I put a general validation message next to the Save button too, e.g. 'Please resolve the validation errors above' so the user knows why the page hasn't submitted?</p>
