I have tried to use dynamic loading with the dhtmlTreeGrid but I have a problem with Drag and Drop if dynamic loading is used. Is it possible to use Dynamic Loading + Drag and Drop or are they mutually exclusive functions in the treeGrid?
This problem was confirmed and fixed in initial build of dhtmlxTreeGrid 1.3, the fix will be available as part of next build
