The behaviour of DropDownLists with AutoPostBack and RadAjax (for ASP .NET AJAX) is different between IE and other browsers.
In IE, if the user uses the keyboard to change the selected value of a combo box, the AutoPostBack fires immediately. In other browsers the post back only occurs when the user tabs focus away from the control.
This behaviour is particularly annoying because the control loses focus
. I would describe this problem as a bit of a show stopper really.
I was wondering if anyone has a good work around or if there are plans to fix this behaviour.
BTW I believe that jquery fixes IE's change behaviour. Perhaps the same fix could be applied in RadAjax?
