Migrating from DHTMLGrid version 1.5 to Version 1.6

Our application currently uses Version 1.5.On Migrating from version 1.5 to 1.6 , we are facing problems with the Drag and Drop, Event handlers.We are using setOnEditCellHandler and setDragHandler methods.On exploring , we found that we have to include the depprecated js file. But still we are facing some strange errors like dthmlxHierarchy is undefined even deppreciated js files are used.



Could you guide us with the steps of migration and also which api should be migrated.Thanks in advance.

to include the depprecated js file
Correct, event system was changed, so you need to update code or include _deprecated.js

>>But still we are facing some strange errors like dthmlxHierarchy is undefined even deppreciated js files are used.
If you are using TreeGrid - be sure that both components are from the same version ( both 1.5 or both 1.6 ) , mixing different versions of Grid and TreeGrid can cause such errors.
