Does TreeGrid use any ActiveX objects in IE?
In Internet Explorer 5.0, 5.5 and 6.0 is AJAX communication done by ActiveX object XmlHttpRequest. This object is marked as safe. But if your visitor has forbidden using all ActiveX objects, you cannot use AJAX. But you can always use standard synchronous communication by page submit. But AJAX is now standard communication on internet. See also NoTryActiveX property. The XmlHttpRequest is the only ActiveX object the TreeGrid uses (and only for AJAX).
