arg = eventArgs.get_argument();
The ContextMenuItem that is clicked is determined by the argument passed, the argument is either a 0,1, or 3 which is the location of the item in the ContextMenu (see contextmenu.gif). I have checked that the argument being passed back is correct. I have used the __doPostBack function in the past to click on a ContextMenu in exactly the same fashion. I have checked the page source and the ID in the __doPostBack matches the ID of the ContextMenu exactly except all the _ have been replaced by $ which was needed before to have it work. Any ideas why I cannot get it to trigger a "click" this time?
