Any ideas. I was able to stop it, but now it's back and i'm not sure why now... I haven't really changed anything...

You'll be better off posting this in the ASP.NET forum (forum855) but the error is telling you that the textbox named "Dg__ctl2_txtDueDate" is outside of the <form> tag. I would check your HTML code and see why.
