[aliebrahimi2015]

hi
how to Error Handling when Create or update record (inline and incell) with kendo api?

[HttpPost]
public virtual async Task CreatePersonnels([Bind(Prefix = "models")]IEnumerable models)
{
_accountService.Value.AddPersonnels(new List(model);
await _unitOfWork.SaveAllChangesAsync();
}
var queryString = Request.Url.ParseQueryString().GetKey(0);
var request = JsonConvert.DeserializeObject(queryString);
var resultData = new List();
return Json(resultData.AsQueryable().ToDataSourceResult(request, ModelState));
}
ModelState not use with ToDataSourceResult

how to use server error in client?
