If I move a task and drop it in the same place, it is sent to the server. When a link exists and drags the task, the link corrects and pulls the task back to where it was. How can I prevent it from sending to the server what was not actually modified? Is the current behavior correct?
Hi @douglas!
You can compare the task’s start_date
values using arguments of the callback function of the onBeforeTaskChanged
event and return false
if they are the same.

Please check the snippet how it can be implemented:

When I move a task, it works fine. But when I move a ‘project’ to another date, the subtasks are not updated. I saw in the console that the old date and the current date are the same in the subtask. How to solve this?
gantt.config.drag_project=true;
Hi @douglas!
If you use gantt.config.drag_project=true
then please add checking task type in the condition of canceling the task’s update:
...
if (task.type == "project" && mode == "move" || mode == "resize") {
...
Here is a snippet:

Maybe I was not clear.
When I move a ‘project’ to another date, the subtasks are not updated on the server. See the video.
Hi @douglas!
It appears to be a bug on our end using gantt.config.drag_project=true;
. I’ve submitted it to our internal tracker, and the dev team will start fix it and it will be published with one of the next bugfix releases.
As a workaround for the issue you can check the type of the task in the onAfterTaskDrag
event listener.
https://docs.dhtmlx.com/gantt/api__gantt_onaftertaskdrag_event.html
And if its type is project
update its children tasks.
Here is a snippet you can see how it can be implemented:

Note I’ve also modified date values camparing and added it in the compareDateValuesToSimilar()
function.
Hello Douglas,
I couldn’t reproduce the issue in the current version:

Could you clarify if the bug still affects you?
