Hi,
Thanks for your response.

Please follow my implementation as below:

#In .html file:

 

#In .js file:

lockerInGroupData = ej.DataManager({
        url: "/api/LockerAPI/GetAllLocker/?Level=" + level + "&ControllerIMEI=" + controllerdeviceimei + "&GroupLocker=" + group + "&Page=" + cPageLocker,
        adaptor: new ej.WebApiAdaptor(),
        offline: true,
    });

    lockerInGroupData.ready.done(e => {
        if (e.result != null) {
            $("#DvAllLockerInGroup").ejGrid({
                dataSource: ej.DataManager({
                    json: e.result.locker,
                    adaptor: new ej.remoteSaveAdaptor(),
                    crudUrl: "CrudLevelInGroupAction",
                }),
                allowPaging: true,
                pageSettings: { pageSize: 25 },
                locale: "vi-VN",
                editSettings: {
                    allowDeleting: true,
                    showDeleteConfirmDialog: true,
                },
                columns: [
                    { field: "locker.lockerId", visible: false, isPrimaryKey: true, isIdentity: true },
                    { field: "locker.createdAt", visible: false },
                    { field: "locker.createdBy", visible: false },
                    { field: "locker.updatedAt", visible: false },
                    { field: "locker.updatedBy", visible: false },
                    { field: "controller.level", headerText: "Tầng", width: 60, textAlign: "center", headerTextAlign: "center" },
                    { field: "locker.label", headerText: "Nhãn", width: 70, textAlign: "center", headerTextAlign: "center" },
                    { field: "locker.position", headerText: "Mô tả vị trí", textAlign: "center", headerTextAlign: "center" },
                    { field: "locker.controllerDeviceImei", headerText: "Thiết bị điều khiển", textAlign: "center", headerTextAlign: "center" },
                    {
                        commands: [
                            { type: "delete", buttonOptions: { text: "" } },
                        ],
                        headerTextAlign: "center",
                        textAlign: "center",
                        width: 50,
                    }
                ],
            });
        }
    });

The result of DataManager could be downloaded here: https://drive.google.com/file/d/1fsGhB46q-Atv9hVPx3mBc5BnbkYhZmgv/view?usp=sharing
The attached file for the result also was added


p/s: I captured some images (the different table but they are the same in the implementation) 
P1: before delete (total item equal 9)



after the first row has been deleted

Toan

Hi,

Sorry for this inconvenience

I am a little bit busy this week.
I tried by adding the toolbar action utility like you used to. It seems to works, the total item also updated after the deletion. But, with my custom delete button for each row,

                {

                    headerText: "Tiện ích",
                    commands: [
                        { type: "delete", buttonOptions: { text: "<i class='far fa-trash-alt'></i>" } },
                    ],
                    headerTextAlign: "center",
                    textAlign: "center",
                    width: 100,
                }
The delete operation is incorrect.

Moreover, When I use my delete button, If I delete the rows from top to bottom, The CrudAction will send to the server the same identity key for all rows. That means, If I delete 10 rows from the first to tenth position, The client only sends the "remove" action with the identity key of the first row.

Thanks,
Toan

Hi Toan,

Sorry for the inconvenience caused.

We are unable to reproduce your reported problem at our end. We need to ensure the following scenarios from your end.

  1. Please confirm that normal deleting through delete icon from toolbar working at your end?
  2. Does the dataSource GetAllControllerDevice has been called again after performing delete action at server end?
  3. If possible replicate the issue in the above sample and revert us back.
Also we have created the new Ticket for this query and  look into your issue further to resolve your problem.
