I'm using the load ondemand with the tooltipmanager just as in the online example, this works fine. However, I also have a RadToolBar on my page which is surrounded by an updatePanel. Whenever an event is fired from the toolbar, it is showing the tooltip. I tried to find a work around by handling the
OnClientBeforeShow with the following code
//Any ajax event will cause the tooltip to show. So we want to make sure
//the ajax event came from the grid and not i.e.(toolbar)
var str = sender.get_TargetControlID();
var pos = str.indexOf("LocationServiceGridView");
however, when you set_cancel(true) it does stop the tooltip from showing but then the event that was suppose to fire from the toolbar cancels as well.
