使用具有ID的模型加载局部视图。 BeginForm返回已编辑的模型，但是ID丢失了吗？

Question

I have a model:

public class Wellbore
{
    public int Id { get; set; }
    [DisplayName("Planned Depth")]
    public double PlannedDepth { get; set; }
    [DisplayName("Reference Depth")]
    public double ReferenceDepth { get; set; }
    [DisplayName("Reference Point")]
    public string ReferencePoint { get; set; }
    [DisplayName("Use Section List")]
    public bool UseSectionList { get; set; }
    [DisplayName("Well Fluid Specific Gravity")]
    public double WellFluidSpecificGravity { get; set; }
    public List<WellboreSection> WellboreSections { get; set; }
    public int WellId { get; set; }
}

And i have a controller

    public ActionResult Index(int wellId)
    {
        var wellbore = _service.FindBy(x => x.Id == wellId).SingleOrDefault();
        return PartialView("~/Views/WellManagement/Wellbore.cshtml", wellbore);
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public void Wellbore_Edit([DataSourceRequest] DataSourceRequest request, Wellbore wellbore)
    {
        if (wellbore != null && ModelState.IsValid)
        {
            wellbore = _service.Edit(wellbore);
        }
    }

And the view....

@using (Html.BeginForm("Wellbore_Edit", "Wellbore", FormMethod.Post, new {@class = "form-horizontal"}))
{
    <div class="form-group">
        @Html.LabelFor(m => m.Id, new { @class = "col-md-3 control-label" })
       <div class="col-md-3">
           @Html.TextBoxFor(m => m.Id, new { @class = "form-control", disabled = "disabled" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(m => m.ReferenceDepth, new { @class = "col-md-3 control-label" })
        <div class="col-md-3">
            @Html.TextBoxFor(m => m.ReferenceDepth, new { @class = "form-control" })
        </div>
    </div>

And so on....

When i load the view with the Index method in the controller, everything works fine. The object contains all of the appropriate values.

When i have done my editing in the view, i click save, and the form posts back. I recieve an object in the Wellbore argument, and if i look at it, all of the properties has values, except Id and WellId....

WellId is not used in the form, so this i might understand, but Id is defenitly used. How come this is is not in the object on it's way back? How does these objects get created? Whats the internal function of this....

Answer 1

这是因为disabled =“ disabled”请使用@ readonly =“ readonly”代替disabled

@Html.TextBoxFor(m => m.UserName, new {@readonly="readonly"})
