Question

我已尝试过在网上和网上其他地方找到的几个解决方案，但我仍然无法让服务器发送错误以正确显示在jqgrid编辑表单上。我已经在jqgrid的afterSubmit方法中添加了断点但它从未被命中。我已将其简化为只显示警报，如果方法已执行但没有任何工作。我最终得到的是堆栈跟踪显示在编辑表单的标题中。我错过了什么？

JQGrid代码

[ResponseType(typeof(HttpResponseMessage))]
[HttpPut]
public HttpResponseMessage Put(int id, [FromBody] InvoiceTypeModel item)
{
    if (item == null)
        return Request.CreateErrorResponse(HttpStatusCode.BadRequest, "Could not read Invoice Type from body");

    InvoiceType originalItem = db.InvoiceTypes.FirstOrDefault(x => x.Id == id);

    if (originalItem == null || originalItem.Id != id)
    {
        item.Id = 0;
        Post(item);
    }

    InvoiceType nameMatchItem = db.InvoiceTypes.FirstOrDefault(x => x.Name == item.Name);
    if (nameMatchItem != null && nameMatchItem.Id != item.Id)
        return Request.CreateErrorResponse(HttpStatusCode.Conflict, "You can't have more than one record with the same name");

    if (ModelState.IsValid && id == item.Id)
    {
        try
        {
            item.Id = id;
            ObjectHelper.CopyPropertyValues(item, originalItem);
            db.InvoiceTypes.ApplyCurrentValues(originalItem);
            db.SaveChanges();
        }
        catch (DbUpdateConcurrencyException)
        {
            return Request.CreateResponse(HttpStatusCode.NotFound, "Record not found");
        }
        catch (Exception ex)
        {
            string c = ex.Message;
        }

        return Request.CreateResponse(HttpStatusCode.OK, "Update Successful");
    }
    else
    {
        return Request.CreateErrorResponse(HttpStatusCode.BadRequest, "Could not save to the database.");
    }
}

Web API控制器方法代码

[HttpPost]
public ActionResult EditData(string oper, int? Id, string Name, DateTime? DateCreated, int? Active)
{
    InvoiceTypeModel cn = new InvoiceTypeModel();
    switch (oper)
    {
        case "add":
        {
            cn.Id = 0;
            cn.Name = Name;
            cn.DateCreated = DateTime.Now;
            cn.UpdatedBy = User.Identity.Name;
            cn.Active = true;
            _invoiceTypeRepository.Create(cn);
            return Content("true");
        }
        case "del":
        {
            _invoiceTypeRepository.Delete((int) Id);
            return Content("true");
        }
        case "edit":
        {
            cn.Id = (int) Id;
            cn.Name = Name;
            cn.DateCreated = (DateTime) DateCreated;
            cn.DateUpdated = DateTime.Now;
            cn.UpdatedBy = User.Identity.Name;
            cn.Active = Active == 1;
            _invoiceTypeRepository.Upsert(cn);
            return Content("true");
        }
    }
    return Content("false");
}

这是网页控制器代码

          int n = int.Parse(textBox7.Text); ;
            int[] numbers = new int[n];
            for (int i = 0; i < n; i++)
            {
                numbers[i] = int.Parse(textBox1.Text);
            }
           // var array = new short[] { 4, 4, 5, 6,9 };

            var sum = numbers.Select(x => (int)x).Sum();
            var avg = numbers.Select(x => (int)x).Average();
            var max = numbers.Select(x => (int)x).Max();
            var min = numbers.Select(x => (int)x).Min();

            textBox4.Text = sum.ToString();
            textBox5.Text = avg.ToString();
            textBox2.Text = min.ToString();
            textBox3.Text = max.ToString();

这是编辑表单收到错误后的部分屏幕截图。这是正确的信息，409冲突但格式化没有正确发生。
