我想在Controller中为我的模型设置默认值,但它无法在创建页面中显示。
TestModel代码:
public class TestModel
{
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "yyyy/MM/dd", ApplyFormatInEditMode = true)]
public DateTime StartTime { get; set; }
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "yyyy/MM/dd", ApplyFormatInEditMode = true)]
public DateTime EndTime { get; set; }
public string Description { get; set; }
}
控制器代码:
public ActionResult Create()
{
var model = new TestModel();
model.StartTime = DateTime.Now;
model.EndTime = DateTime.Now.AddDays(10);
model.Description = "This is a default value";
return View(model);
}
查看页面:
<div class="form-group">
@Html.LabelFor(model => model.StartTime, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.StartTime)
@Html.ValidationMessageFor(model => model.StartTime)
</div>
</div>

您需要具有如下所示的模型类属性:
[DataType(DataType.Date), Required]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime StartTime { get; set; }
[DataType(DataType.Date), Required]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime EndTime { get; set; }
当您使用[DataType(DataType.Date)]
装饰模型属性时,ASP.NET MVC
中的默认模板会生成type="date"
的输入字段。

将模型更改为:
public class TestModel
{
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime StartTime { get; set; }
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime EndTime { get; set; }
public string Description { get; set; }
}
很明白。导致显示格式字符串不正确。

你的剃刀如下:
@Html.TextBoxFor(x => x.Date, "{0:yyyy-MM-dd}", new { @class = "form-control",@type = "date"})

将DataAnnotations用于st默认值:
[DefaultValue(System.DateTime.Now)]
public DateTime DateTo { get; set; }
