ModelState.IsValid总是因为datetime.now假 [英] ModelState.IsValid is always false because of datetime.now

问题描述

我有一个ASP.NET MVC应用程序并在编辑和创建操作设置我的班日期字段通过 datetime.now 。一切工作正常，我可以添加和编辑记录。但是，当我想删除这些记录 ModelStata.IsValid 总是假和误差 值2015年4月25日上午09时34分39秒是无效的注册时间。注册时间是我场的显示名称。

下面是我的行为code：

 公众的ActionResult创建（[DataSourceRequest] DataSourceRequest要求，InvtGroups invtGroup）
{
    如果（invtGroup = NULL＆放大器;！＆安培; ModelState.IsValid）
    {
        invtGroup.DDate = DateTime.Now;
        repo.Insert（invtGroup）;
    }
    返回JSON（新[] {} invtGroup .ToDataSourceResult（请求的ModelState））;
}
[HttpPost]
公众的ActionResult删除（[DataSourceRequest] DataSourceRequest要求，InvtGroups invtGroup）
{
    如果（invtGroup = NULL＆放大器;！＆安培; ModelState.IsValid）
        repo.Delete（invtGroup）;
    返回JSON（新[] {} invtGroup .ToDataSourceResult（请求的ModelState））;
}
 

这是我的模型（我使用实体框架code在前）：

 公共类InvtGroups：用户
{
    [键]
    [专栏（类型名=VARCHAR），StringLength（21）]
    公共字符串CGROUP code {搞定;组; }    [专栏（类型名=VARCHAR），StringLength（50）]
    公共字符串CGroupName {搞定;组; }    [专栏（类型名=BIGINT）]
    公众的Int64？李code1 {搞定;组; }    [专栏（类型名=BIGINT）]
    公众的Int64？李$ C $ {C2获得;组; }    [专栏（类型名=BIGINT）]
    公众的Int64？李$ C $ {C3获得;组; }    [专栏（类型名=BIGINT）]
    公众的Int64？李$ C $ {C4获得;组; }    [专栏（类型名=BIGINT）]
    公众的Int64？李$ C $ {C5获得;组; }
}
 

和用户类：

 公共类用户
{
    [专栏（类型名=VARCHAR），StringLength（20）]
    公共字符串CUserNo {搞定;组; }    [专栏（类型名=DATETIME）]
    公众的DateTime？ DDate {搞定;组; }
}
 

解决方案

您可以执行以下操作：

1 _Layout.cshtml

 ＆LT;脚本＆GT;
        kendo.culture（EN-GB）;
        VAR文化= kendo.culture（）;
        culture.calendar.patterns.d =DD MMM YYYY; // 2015年2月25日
        culture.calendar.patterns.D =DD MMM YYYY;
        culture.calendar.patterns.t =HH：MM; // 16:45
        culture.calendar.patterns.T =HH：MM;
        culture.calendar.patterns.g =DD MMM YYYY HH：MM;
        culture.calendar.patterns.G =DD MMM YYYY HH：MM;
 ＆LT; / SCRIPT＆GT;
 

2 - Global.asax中

 保护无效的Application_BeginRequest（对象发件人，EventArgs的发送）
        {            CultureInfo的信息=新的CultureInfo（EN-GB）;
            info.DateTimeFormat.ShortDatePattern =DD MMM YYYY;
            info.DateTimeFormat.LongDatePattern =DD MMM YYYY HH：MM;
            info.NumberFormat.CurrencyDecimalDigits = 2;
            info.NumberFormat.CurrencyGroupSeparator =，;
            info.NumberFormat.NumberDecimalDigits = 2;
            Thread.CurrentThread.CurrentCulture =信息;
            Thread.CurrentThread.CurrentUICulture =信息;
        }
 

以上code将建立日期格式，格式也为您的整个应用程序的数量。

I have an ASP.NET MVC application and in the edit and create actions I set date field of my class by datetime.now. Everything works fine and I can add and edit records. But when I want to delete those records ModelStata.IsValid is always false and the error is "The value '4/25/2015 9:34:39 AM' is not valid for register time." Register time is display name of my field.

Here is my actions code:

public ActionResult Create([DataSourceRequest]DataSourceRequest request, InvtGroups invtGroup)
{
    if (invtGroup != null && ModelState.IsValid)
    {
        invtGroup.DDate = DateTime.Now;
        repo.Insert(invtGroup);
    }
    return Json(new[] { invtGroup }.ToDataSourceResult(request, ModelState));
}
[HttpPost]
public ActionResult Delete([DataSourceRequest]DataSourceRequest request, InvtGroups invtGroup)
{
    if (invtGroup != null && ModelState.IsValid)
        repo.Delete(invtGroup);
    return Json(new[] { invtGroup }.ToDataSourceResult(request, ModelState));
}

This is my Model (I'm using Entity Framework Code First):

public class InvtGroups : User
{
    [Key]
    [Column(TypeName = "VARCHAR"), StringLength(21)]
    public string CGroupCode { get; set; }

    [Column(TypeName = "VARCHAR"), StringLength(50)]
    public string CGroupName { get; set; }

    [Column(TypeName = "BIGINT")]
    public Int64? LiCode1 { get; set; }

    [Column(TypeName = "BIGINT")]
    public Int64? LiCode2 { get; set; }

    [Column(TypeName = "BIGINT")]
    public Int64? LiCode3 { get; set; }

    [Column(TypeName = "BIGINT")]
    public Int64? LiCode4 { get; set; }

    [Column(TypeName = "BIGINT")]
    public Int64? LiCode5 { get; set; }
}

And the user class:

public class User
{
    [Column(TypeName = "VARCHAR"), StringLength(20)]
    public string CUserNo { get; set; }

    [Column(TypeName = "DATETIME")]
    public DateTime? DDate { get; set; }
}

解决方案

You can do the following:

1- _Layout.cshtml

 <script>
        kendo.culture("en-GB");
        var culture = kendo.culture();
        culture.calendar.patterns.d = "dd MMM yyyy"; // 25 Feb 2015
        culture.calendar.patterns.D = "dd MMM yyyy";
        culture.calendar.patterns.t = "HH:mm";   // 16:45
        culture.calendar.patterns.T = "HH:mm";
        culture.calendar.patterns.g = "dd MMM yyyy HH:mm";
        culture.calendar.patterns.G = "dd MMM yyyy HH:mm";
 </script>

2- Global.asax

   protected void Application_BeginRequest(object sender, EventArgs e)
        {

            CultureInfo info = new CultureInfo("en-GB");
            info.DateTimeFormat.ShortDatePattern = "dd MMM yyyy";
            info.DateTimeFormat.LongDatePattern = "dd MMM yyyy HH:mm";
            info.NumberFormat.CurrencyDecimalDigits = 2;
            info.NumberFormat.CurrencyGroupSeparator = ",";
            info.NumberFormat.NumberDecimalDigits = 2;
            Thread.CurrentThread.CurrentCulture = info;
            Thread.CurrentThread.CurrentUICulture = info;
        }

the above code will setup the date format and also the number formatting for your whole application
