Can you tell me if the dhtmlXTreeGrid supports dynamic load

Can you tell me if the dhtmlXTreeGrid supports dynamic
loading?  The scenario I have in mind is that all the branch nodes are
loaded (those nodes not having grid cells) initially, if a branch having
children is expanded the children with grid cells are dynamically loaded.

dhtmlXTreeGrid supports such
functionality. You can specify a “child” attribute of element in XML,
and that row will load XML with list of childs from server on opening.
