Save Gantt Batch

When saving a Gantt, it is not stored in the database when it is modified by light box, inline editing, drag,
Please let me know how to store it in database at once when you click any save button

Hello,
To save the data to the database, you need to integrate Gantt with the server side. Usually, you just need to add the Datta Processor and specify the server URL, for example:

var dp = new gantt.dataProcessor("/data");
dp.init(gantt);
dp.setTransactionMode("REST");

In the following article, you can find more information about server-side integration:

If you use the backend, the following articles explain how to configure backends to work with Gantt:
