title: Another object on this page already uses ID 'XXXXXXX'
body: <p>I am receiving a warning from Visual Studio 2010 that every single control in my ASP.net project has a duplicate ID. This is obviously not the case, since I named all hundred or so controls on the page myself, and I made sure not to allow any duplicates. Has anyone else run into this and found a fix?</p>
  
  <p>Thanks</p>
