Question

问题

我使用Telerik UI进行ASP.NET MVC网格控制来编辑数据，但返回控制器的日期格式无效且ModelState无效。我正在使用新西兰格式的＆＃34; dd / MM / yyyy＆＃34;。所有日期都在网格中正确显示，也可以在内联编辑时显示。在将数据发布回控制器期间似乎发生了这个问题。

我尝试了什么

从stackoverflow上与此问题相关的无数文章中，大多数指向无效的文化设置。但是我在布局文件中为telerik网格设置了文化，见下文。我还在启动文件中为asp.net mvc core设置了全球文化。

错误消息

＆＃34;价值＆＃39; 20/10/2010 12:00:00 am。＆＃39;对于截止日期无效。＆＃34;

这是我的代码：

Fiddler Raw Response：

{"Data":[{"InvoiceID":237,"CompanyID":15,"Description":"Monthlyy","InvoiceDate":null,"DueDate":null,"Tax":0.0,"Discount":0,"Paid":true,"Company":{"CompanyID":15,"Name":"Engineering","Address":null,"Phone":null,"Fax":null,"CountryID":null,"Comment":null},"InvoiceItems":[]}],"Total":1,"AggregateResults":null,"Errors":{"DueDate":{"errors":["The value '20/10/2010 12:00:00 a.m.' is not valid for Due Date."]},"InvoiceDate":{"errors":["The value '30/09/2010 12:00:00 a.m.' is not valid for Invoice Date."]}}}

我的观点：

@(Html.Kendo().Grid<GearBox.Models.Invoice>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.Description);
        columns.Bound(p => p.Company.Name).Filterable(ftb => ftb.Multi(true).Search(true));
        columns.Bound(p => p.InvoiceDate).Width(130);
        columns.Bound(p => p.DueDate).Width(130);
        columns.Bound(p => p.Paid).Width(80).ClientTemplate("<input type='checkbox' disabled='disabled' #= Paid ? checked='checked' :'' # />");
        columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);
    })
    .ToolBar(toolbar => toolbar.Create())
    .Pageable(pageable => pageable
       .Input(true)
       .Numeric(false)
     )
    .Sortable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Model(model => model.Id(p => p.InvoiceID))
        .Events(events => events.Error("onError"))        
        .Create(update => update.Action("Invoices_Create", "Invoice"))
        .Read(read => read.Action("Invoices_Read", "Invoice"))
        .Update(update => update.Action("Invoices_Update", "Invoice"))
        .Destroy(update => update.Action("Invoices_Destroy", "Invoice"))

    )
    .Editable(editable => editable.Mode(GridEditMode.PopUp))
)

启动

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    ...
    app.UseRequestLocalization(BuildLocalizationOptions());
    ...
    app.UseKendo(env);
}

private RequestLocalizationOptions BuildLocalizationOptions()
{
    var supportedCultures = new List<CultureInfo>
    {
        new CultureInfo("en-NZ")          
    };

    var options = new RequestLocalizationOptions
    {
        DefaultRequestCulture = new RequestCulture("en-NZ"),
        SupportedCultures = supportedCultures,
        SupportedUICultures = supportedCultures
    };

    return options;
}

布局文件的标题部分

<head>
       ... 
        @{              
            var culture = System.Globalization.CultureInfo.CurrentCulture.ToString();
        }

        <script src="@("https://kendo.cdn.telerik.com/2016.2.607/js/cultures/kendo.culture." + culture + ".min.js")"></script>

        <script>
            //Set the current culture
            kendo.culture("@culture");
        </script>
        ....
</head>

模型

[ScaffoldColumn(false)]
    [Display(Name = "ID")]
    [DataType("Integer")]
    //[Range(0, int.MaxValue)]
    public int InvoiceID { get; set; }

    [Required]
    public int CompanyID { get; set; }

    [Required]
    [MaxLength(15)]      
    public string Description { get; set; }

    [Display(Name = "Invoice Date")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}",
           ApplyFormatInEditMode = false)]
    public DateTime? InvoiceDate { get; set; }

    [Display(Name = "Due Date")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}",
           ApplyFormatInEditMode = false)]
    public DateTime? DueDate { get; set; }

编辑模板

@model DateTime?

@(Html.Kendo().DatePickerFor(m => m).HtmlAttributes(new { style = "width:80%" })))

Answer 1

经过大量浪费时间后，问题已确定与Windows 10上en-NZ的默认区域设置有关。将区域设置中的日期格式从AM和PM更改为上午和下午。解决了这个问题。这是一个短期的解决方法。
