title: C# WinForms ErrorProvider Control
body: <p>Does anyone know if there is a way to get a list of controls that have the ErrorProvider icon active.  ie. any controls that failed validation.  I'm trying to avoid looping all controls in the form.</p>
  
  <p>I'd like to display some sort of message indicating how many errors there are on the form.  As my form contains tabs I'm trying to make it apparent to the user that errors may exist on inactive tabs and they need to check all tabs.</p>
  
  <p>Thanks</p>
