I have customers that have reported this morning that our web application that uses asp.net ajax is not longer working correctly after they installed the windows updates last night (7/10/2007).  The problems that we are seeing is a page that has a gridview inside of an update panel displays some of the markup of the page.  When they click the button that should trigger the update panel, the page does a full postback instead of a partial.  The Update Progress doesn't show like it should either.  After the postback, it may or may not show the page correctly, but none of the buttons work anymore.  We found that this is only a problem with IIS 6.

 If anyone knows what update may cause this so we can uninstall that update to get our customers site back up and running please let me know.  I searched the forum, but couldn't find any similar problems.  Are there others that are seeing similar problems with the windows updates?

Hi buckeyes,

Has your problem been resolved yet?  If yes, Sharing your work will be greatly appreciated.

We haven't found a solution yet other than rolling back the updates. 

Hi buckeyes, 

buckeyes:

Would you please tell us which update causes the issue and your system environments?   We will check it and thanks for your feedback.

Sorry that I haven't gotten back to you on this.  We had a member of the IIS team looking into this as well and so we were waiting for their reply.  Anyway they were able to point us in the right direction.  The problem was caused by some of our JavaScript after the install of KB928365.  We were referring to controls like:

document.getElementById('ct100_MyTextBox')

We changed that to

document.getElementById('<%=MyTextBox.ClientID%>')

That has fixed our problems.
