Hello,
With the current implementation of the RadGantt control, there is no direct option to disable the drag-and-drop functionality in the "treelist" part. Nevertheless you could handle the
save event of the kendo widget and cancel it, if the
e.values object contains either the
parentId or
orderId fields, since these are the two fields which are updated during the drag-and-drop operation.
