Drag and drop in dhtlxtreegrid


I’m dragging and dropping the elements in my grid. I m doing changeRowId based on the drag and drop. First time, it is working properly. If i try to do drag and drop multiple times, i’m getting errors like ‘null’ is null or not an object , ‘childnodes’ is null or not an object .Anyone Please help me in resolving this issue

Thanks in advance

Please, make sure that changing the row ids you don’t create duplicated ids, or don’t set the row if to “0”.
