查看强类型查看模型不返回模型回控制器上回发

我有一个PartialView强类型的视图模型查看强类型查看模型不返回模型回控制器上回发

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<VATRateManager_MVC.Models.ViewModels.RateControlEditViewModel>" %> 

<script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> 
<script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> 

<% Html.EnableClientValidation(); %> 
<% using (Html.BeginForm("Edit", "Rate", FormMethod.Post)) 
{ %> 
<%=Html.ValidationSummary() %> 

<%=Html.HiddenFor(Model => Model.ParentID)%> 
<%=Html.HiddenFor(Model => Model.ParentTypeID)%> 
<%=Html.HiddenFor(Model => Model.ParentTypeDescription)%> 
<%=Html.HiddenFor(Model => Model.RateID)%> 

<div > 
    <%=Html.LabelFor(Model => Model.RateValue)%> 
    <%=Html.DisplayFor(Model => Model.RateValue) %> 
</div> 

<div> 
    <%=Html.LabelFor(Model => Model.StartDate)%> 
    <%=Html.DisplayFor(Model => Model.StartDate, new { @class = "date" })%> 
    <%-- <%=Html.EditorFor(Model => Model.StartDate, new { @class = "date" })%>--%> 
</div> 

<div> 
    <input type="submit" name="button" value="Edit"/> 
</div>

继承人的视图模型

public class RateControlEditViewModel 
{ 
    /// <summary>The parent ID is the Rate ID for the Current record. </summary> 
    [HiddenInput(DisplayValue = false)] 
    public int ParentID { get; set; } 

    /// <summary>The parent Type ID is the Type ID for the Current record. </summary> 
    [HiddenInput (DisplayValue= false)] 
    public int ParentTypeID { get; set; } 

    [HiddenInput(DisplayValue = false)] 
    public string ParentTypeDescription { get; set; } 

    /// <summary>Rate ID for current record, may be null if adding new rate. </summary> 
    [HiddenInput(DisplayValue = false)] 
    public int? RateID { get; set; } 

    /// <summary>Percentage VAT Rate to 2 decimal places. </summary> 
    [DisplayName("VAT Rate (%)")] 
    [Required(ErrorMessage ="Please Supply VAT Rate as percentage value")] 
    [Range(typeof(Decimal), "0","100")] 
    public decimal RateValue { get; set; } 

    /// <summary>Start date from which this VAT Rate will be active, the start date will also be 
    /// the same value for the previous records End Date to ensure there are no gaps in the Rate.</summary> 
    [DisplayName("VAT Rate Start Date")] 
    [DataType(DataType.Date)] 
    [Required(ErrorMessage="Please Supply Start date from which this VAT rate will become active")] 
    public DateTime? StartDate { get; set; } 

}

而且继承人的控制方法。 ..

[ActionName("Edit")] 
    [AcceptVerbs(HttpVerbs.Post)] 
    public ActionResult Edit(string button, RateControlEditViewModel model) 
    { // Do Stuff here 
    }

我的问题是对象“RateControlEditViewModel模型”传递到控件ller已经失去了它的一些价值... 基本上屏幕应该显示一个对象列表，当你点击“编辑”一个新的视图应该打开显示你点击的1个对象以允许你编辑它 - 但它会丢失值。帮助！

好的，看来，如果您使用“DisplayFor”，模型属性不会填充。使用下面的示例，我接收回控制器的值是“HiddenFor”对象中的值，但不是“DisplayFor”中的值。

<%=Html.HiddenFor(Model => Model.ParentID)%> 
<%=Html.HiddenFor(Model => Model.ParentTypeID)%> 
<%=Html.HiddenFor(Model => Model.ParentTypeDescription)%> 
<%=Html.HiddenFor(Model => Model.RateID)%> 
<div > 
    <%=Html.LabelFor(Model => Model.RateValue)%> 
    <%=Html.DisplayFor(Model => Model.RateValue) %> 
</div> 

<div> 
    <%=Html.LabelFor(Model => Model.StartDate)%> 
    <%=Html.DisplayFor(Model => Model.StartDate, new { @class = "date" })%> 
</div>

要解决此我只是包括 “HiddenFor” S对其他2个属性:)

<%=Html.HiddenFor(Model => Model.RateValue)%> 
<%=Html.HiddenFor(Model => Model.StartDate)%>

简单，我认为 - 希望它可以帮助别人。
