I finally found it, I got so use to the standard way of report viewer. when you add the an report viewer control on the designer, create the rdlc file by default , with you infragistics you have to simply right click and add new item "igr". I didnt think to do that at first because of the old way . Also the report ultra explorer only shows up when a igr file is created, if its not created and you just have the ultrareviewer on the designer with no reportviewer, you can not get access to the report data explorer.
