im confused, the w3c validation service seems to be saying that asp.net cannot legally render a hidden field inside a form tag on the page, have a look at this …

http://validator.w3.org/check?uri=http%3a%2f%2fmotcombegarage%2eco%2euk%2f

from what i can tell it seems to be saying that the following code sample is invalid markup WTF !!!

<html>
<head> ... header stuff ... </head>
<body>
  <form method="post" action="" id="ctl01">
    <div class="aspNetHidden">
      <input type="hidden" name="ctl09_HiddenField" id="ctl09_HiddenField" value="" />
      <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTY1NzEyODQ1M2RkJPtW5VtaL7LPuSxnn1JM1yVnOeGAovb8b4b3KShHy4M=" />
      <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWAwKt17cxAr+s9MgFAqjXzJsHz7KyzLpZjYtTK89blY7GgKAElK/5syvVNn4h7rVehcQ=" />
    </div>
     ... other code ...
  </form>
</body>
</html>

This presents 2 problems for me if the code is in fact invalid:

  1. This code is generated by the .net framework for handling postbacks so editing it could be a problem
  2. i have no idea what the valid context for a form field should be (lolz)

Is this a bug or have i done something wrong ???

EDIT:
As pointed out by Peter O below I added the missing div tag in my markup … comparing this to the markup that the validator uses shows that this div whilst present in the markup is apparently not worth validating … so that kinda changes the question to … why is it ignoring that div ? …

Seems a bit odd that you can’t put an input tag inside a form tag directly though … surely thats the point of a form tag, to contain input tags ??

    The only way I’ve seemed to get rid of the message, following the code on your homepage, is to assign a value to the first hidden input

    <div class="aspNetHidden">
<input type="hidden" name="ctl09_HiddenField" id="ctl09_HiddenField" value="toverton" />
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTY1NzEyODQ1M2RkJPtW5VtaL7LPuSxnn1JM1yVnOeGAovb8b4b3KShHy4M=" />
</div>

    In all liklihood, this is most likely a bug.
