Activities of "vsolve"

We are using ABP controller. We tried with UnitOfWork also. Still facing issues.

At the same time, excel data import process also having issues.

/Action Method [HttpGet] public JsonResult List(DataSourceLoadOptions options) { var data = _countryAppService.GetPage(options); return Json(data); }

//Service Layer public LoadResult GetPage(DataSourceLoadOptionsBase options) { var query = _countryRepository.GetAll() .Select(s => new CountryListDto { Id = s.Id, Name = s.Name, }); return DataSourceLoader.Load(query, options); } }

//Cshtml @(Html.DevExtreme().DataGrid<TSolve.Countries.Dto.CountryListDto>() .ID("CountryList") .ShowBorders(true) .AllowColumnReordering(true) .DataSource(d => d.Mvc() .Controller("Country") .LoadAction("List") .UpdateAction("Put") .Key("id") .DeleteAction("Delete")) .Editing(editing => { editing.Mode(GridEditMode.Batch); editing.AllowDeleting(true); editing.AllowUpdating(true); editing.UseIcons(true); }) .Columns(columns => { columns.AddFor(m => m.Name);

                        columns.Add().Type(GridCommandColumnType.Buttons)
                        .Buttons(b =>
                        {
                            b.Add().Icon("edit").OnClick("function(e) { countryAddEdit.showModel(e, countryList.refreshList); }");
                            b.Add().Name(GridColumnButtonName.Delete);
                        });
                    })
                        .Paging(p => p.PageSize(10))
                        .FilterRow(f => f.Visible(true))
                        .HeaderFilter(f => f.Visible(true))
                        .RemoteOperations(true)
                        )
