Question

我有一个ModelState.AddModelError，当Month值（在Viewmodel中指定）等于de DB时，会添加一个错误。但是问题是，当使用模式引导程序时，它不起作用。模态转到唯一的页面，而不是停留在模态视图中

这是我的控制器：

var monthexist = _context.TBL_SalesObjective.Where(x => x.SalesObjectiveID == model.SalesObjectiveID && x.UserID == model.UserID).FirstOrDefault().Month; //verifica o mes no userID e selesid, se existe o mês escolhido

if (monthexist != model.Month)
{
    TBL_SalesObjective item2 = new TBL_SalesObjective();
    item2.Month = (DateTime)model.Month;

    item2.UserID = (int)model.UserID;
    item2.SalesObjectiveMonth = (decimal)model.SalesObjectiveMonth;
    item2.GrossMargin = (decimal)model.GrossMargin;
    item2.ConversionRate = (decimal)model.ConversionRate;
    item2.CreateDate = DateTime.Today;
    item2.CreateBy = userID;

    _context.TBL_SalesObjective.Add(item2);
    _context.SaveChanges();
    return RedirectToAction("Index");
}
else
{
    ModelState.AddModelError("Month", "Error already exist");
    return View(model);
}

这是我的看法以及本月的模式：

[Required]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:dd/MMM/yyyy}")]
[Display(Name = "Select Month")]
public Nullable<System.DateTime> Month { get; set; } 



<div class="form-group">
    @Html.LabelFor(m => m.Month, new { @class = "control-label col-sm-3" })
    <div class="col-sm-9 input-group">
        <input type="text" id="monthPicker" name="Month" placeholder="CheckIn" readonly>
        @Html.ValidationMessageFor(model => model.Month, "", new { @class = "text-danger " })
    </div>
</div>

当我按保存时，视图转到此处： Modal bootstrap error

如何在模态引导程序中进行ModelState.AddModelError？
