This will require adding a JavaScript function to the page and hooking it into the selection-changed event. I'd start with "Hooking to events in the AJAX viewer" <https://trac.osgeo.org/mapguide/wiki/CodeSamples/JavaScript/AJAXViewerEventHooking> and the "MapGuide Viewer API Reference" <http://mapguide.osgeo.org/files/mapguide/docs/2.0/viewerapi.html>.

There are several parameters that will need to be configured in the invoke-url dialog in order to make this work, and of course you must have a page to forward the data to.

I'll admit that the change from MapGuide 6.5 to MapGuide Enterprise is a difficult one; there is much to learn about the new architecture -- it is a dramatically different set of technologies than the old one. Much more of the processing happens server-side now.
