Can ASP.NET validation controls display an exclamation point with tooltip message?

Question

Can the standard ASP.NET Visual Studio validation controls display an icon with a tool tip message instead of text, the way the WinForms ErrorProvider controls work?

If not, is the AjaxToolkit's ValidatorCallout control the best approach? Is this control flakey?
