In case of dhtmlxtree the updates has more complex logic, because tree need to maintain correct hierarchy - child items may be updated only after parent ones updated , so dataProcessor allows data saving only one-by-one, without possibility to do all-at-once saving.


myDataProcessor.setUpdateMode("off")

var list=[ ...array of ids ... ];
for (var i=0; i<list.length; i++){
    tree.moveItem(list[i],....
    myDataProcessor.setUpdated(list[i],true);
}

myDataProcessor.sendData();





This logic is not working , In this only last request is send back to the server......

There is one small mistake in sample above , the correct code is

myDataProcessor.setUpdateMode(“off”)

var list=[ …array of ids … ];

for (var i=0; i<list.length; i++){

    tree.moveItem(list[i],…

    myDataProcessor.setUpdated(list[i],true);
}


myDataProcessor.setUpdateMode(“cell”); //reenable auto-updates
myDataProcessor.sendData();
