In your features documentation you mention that
dhtmlxTreeGrid has the ability to load data dynamically, but it seems that it
can only be loaded by scrolling (a great feature).  However, I was
wondering if it also had the ability to load the tree nodes as they are
expanded (via AJAX).


Sure, the grid can load child rows while expanding
parent row.


You can check samples/pro_treeGrid_dynamic.html
(the  sample available only in PRO package).
