delete selected records

[samaremad]

hello everyone

i want to add checkboxes to the table so that i can select more than one record and press on button to delete them how can i do that ?

[minhhungit]

there is a sample to create checkbox here https://serenity.is/demo/BasicSamples/CancellableBulkAction

code https://github.com/serenity-is/Serene/blob/master/Serene/Serene.Core/Modules/BasicSamples/Grids/CancellableBulkAction/CancellableBulkActionGrid.ts

after you have checkbox, just add new button and call delete service in click() method

debug it please, the error is your code, the error showed that one of your variables is null
it looks you wrote something in your repository or endpoint

[samaremad]

i want to debug the TS. file do you know how to do that?

[samaremad]

hi my friend how are you ?
this function to delete just 1 record if use

for (var i = 0; i < selectedKeys.length; i++)
                            NomineeService.Delete({ EntityId: Q.toId(selectedKeys[i]) }, res => {
                                
                               this.refresh();
                           });

instead of

Q.warning("Should select only one row");

it dosent work correctly and get to deadlock

Sorry but your code is not good
Just use my code when you need to delete only one item

If you want to delete multiple item, should remove this.refresh() out of for loop
But it's not a good way too, better way you will create new endpoint and pass all Ids instead delete one by one, then on server side, you will use for loop to delete record. that means you just call only one request to server and it will include all Ids, after that you can call this.refresh()

Create a class:

public class DeleteMultiRequest: ServiceRequest
    {
        public List<int> Ids { get; set; }
    }

in EndPoint create a new method:

 [HttpPost, AuthorizeDelete(typeof(MyRow))]
        public ServiceResponse DeleteMulti(IUnitOfWork uow, DeleteMultiRequest request)
        {
            request.Ids.ForEach(v =>
            {
                new MyRepository().Delete(uow, new DeleteRequest() { EntityId = v });
            });

            return new ServiceResponse();
        }

event click ôn button delete:

let selectedKeys = this.rowSelection.getSelectedKeys();
    if (selectedKeys != null && typeof selectedKeys != 'undefined' && selectedKeys.length > 0) {
            CategoryService.DeleteMulti({ Ids: selectedKeys.getSelectedAsInt64() }, res => {
                Q.notifySuccess("Row is deleted");
                this.refresh();
            });
    }
    else {
        Q.warning("Please select one row to delete");
    }
