我在我的应用程序中使用2个kendo日期选择器:
<div class="span12">
<div class="span2" style="text-align: right">
Start Date:
</div>
<div class="span2">
@(Html.Kendo().DatePickerFor(m=>m.StartDate))
</div>
<div class="span2" style="text-align: right">
End Date:
</div>
<div class="span2">
@(Html.Kendo().DatePickerFor(m=>m.EndDate))
</div>
<div class="span4">
<button class="btn btn-primary" onclick="getGraphData()">Show</button>
</div>
</div>
单击该按钮时,我会读取这些日期选择器客户端的值,并向API控制器发出POST。
我遇到的问题有时是DateTime参数被错误解析,我使用的是en-GB文化(在我的web.config中指定),但是给定日期为2014年3月1日(3月1日),当时该值由模型绑定器处理,它被解释为03/01/2014(1月3日)。
我的javascript如下:
function getGraphData() {
var startDatePicker = $("#StartDate").data("kendoDatePicker");
var endDatePicker = $("#EndDate").data("kendoDatePicker");
var param = {
StartDate: kendo.toString(startDatePicker.value().toLocaleDateString(), "dd/MM/yyyy"),
EndDate: kendo.toString(endDatePicker.value().toLocaleDateString(), "dd/MM/yyyy")
};
// Do post here
}
我的模型如下:
public class DateRangeParam
{
#region Constructors and Destructors
/// <summary>
/// Initializes a new instance of the <see cref="DateRangeParam"/> class.
/// </summary>
public DateRangeParam()
{
this.EndDate = DateTime.Today.AddDays(1).AddSeconds(-1);
this.StartDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
}
#endregion
#region Public Properties
/// <summary>
/// Gets or sets the end date.
/// </summary>
public DateTime EndDate { get; set; }
/// <summary>
/// Gets or sets the start date.
/// </summary>
public DateTime StartDate { get; set; }
#endregion
}
我认为解决方案是我需要一个自定义模型绑定器来解析日期时间值,所以我创建了(如下所示)并将其注册在Global.asax.cs文件中,但这不起作用,绑定从不我不确定这是不是因为datetime是自定义对象的属性。
public class DateTimeModelBinder : IModelBinder
{
#region Fields
private readonly string _customFormat;
#endregion
#region Constructors and Destructors
public DateTimeModelBinder(string customFormat)
{
this._customFormat = customFormat;
}
#endregion
#region Explicit Interface Methods
object IModelBinder.BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
ValueProviderResult value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
return DateTime.ParseExact(value.AttemptedValue, this._customFormat, CultureInfo.InvariantCulture);
}
#endregion
}
注册如下:
var binder = new DateTimeModelBinder(new CultureInfo("en-GB").DateTimeFormat.ShortDatePattern);
ModelBinders.Binders.Add(typeof(DateTime), binder);
ModelBinders.Binders.Add(typeof(DateTime?), binder);
有谁知道我哪里出错了?
答案 0 :(得分:12)
我没有看到你在global.asax中注册DateTimeModelBinder的地方:
ModelBinders.Binders[typeof(DateTime)] =
new DateAndTimeModelBinder() { CustomFormat = "yyyy-mm-dd" };
