Building ‘easy’ and ‘complex’ user controls or field controls is one of those daily jobs that a SharePoint developer will do when building WCM websites.
Recently whenever I was navigating from the Edit Mode, whether it may be a postback or clicking on a link to a different page, IE8 prompts with this ‘wonderful’ yet ‘awesome’ message:
Here is my custom field control in edit mode
So, as you can see in the above screenshot, I have a repeater and then some command arguments – Remove and Sort – Whenever I tried to remove the item or sort, IE8 halts for at least a minute and then prompts me with that message. Clicking on OK does finish the job, but why this message?. This does not happen in IE6, IE7 and Firefox.
Yes! Go to Tool->Internet Options->Advanced and disable ‘Enable native XMLHTTP support’ and everything works fine!
I think the SharePoint Team should be made aware of this bug as this is indeed a show-stopper in regard to user experience in the Edit Mode (which is very common in WCM websites and upgrading to SP2 does not solve this issue)
Anyone from the SharePoint Team investigate this issue?
