I have a page using a master page, which has an updatepanel and updateprogress in it. On the child page I have a textbox with an AutoCompleteExtender making use of the OnClientPopulated method to format the display of the information retrieved from the web service. In Chrome, this method is called fine if the user executes it first, but if the user does anything else on the page first that causes a postback, the method will not function the same way, since the UL object that contains the items of items does not contain any items at the time that the method is called. However, the list still displays the data as returned from the web service in the list of options, albeit that they cannot be formatted by the OnClientCompleted method. It works fine in IE 7 and above, no problems. Any ideas on why this would happen and only in Chrome? I haven't tested in Firefox or any other browsers.
