最后编辑：问题是 ViewBag.PropName == Model.PropName; 修复：ViewBag.PropName ===> ViewBag.PropName2
这是我第一次发帖；我是新来的，我认为我搞砸了布局......很抱歉！我遇到了一些隐藏下拉列表的客户端验证问题。我正在使用 ASP.NET MVC3，并且在此页面上有很多隐藏的 ddl。但是，验证不适用于某些 ddl。以前有人遇到过这个问题吗？
这是2个属性；1 工作，1 失败
//VALIDATION FAILS
[Required]
[Range(0, 4)]
public int TiresBack { get; set; }
//VALIDATION WORKS
[Required]
[Range(0, 4)]
public int TechnicalState { get; set; }
这是一块剃须刀：
<tr>//THIS DOESN'T WORK
<td style="width: 38%;">
@txtFor("tiresBack")
</td>
//This is JQuery Star-Rating.
<td align="center" id="starsTiresBack">
</td>
<td>
@Html.DropDownListFor(model => model.TiresBack, ViewBag.TiresBack as IEnumerable<SelectListItem>, new { style = "display:none;" })
<input class="blueButton" type="button" id="btnBrandRearTires" value="@txtFor("brandTiresBack")" />
<span>@Html.ValidationMessageFor(model => model.TiresBack)</span> <span>@Html.ValidationMessageFor(model => model.BrandRearTires)</span>
</td>
</tr>
//THIS WORKS
<tr>
<td style="width: 38%;">
@txtFor("technicalState")
</td>
<td id="starsTechnicalState" align="center">
</td>
<td>
@Html.DropDownListFor(model => model.TechnicalState, ViewBag.TechState as IEnumerable<SelectListItem>, new { style = "display:none;" })
<input class="blueButton" type="button" id="btnTechnicalStateDescription" value="@txtFor("technicalStateDescriptionButton")" style="display:none;"/>
<span>@Html.ValidationMessageFor(model => model.TechnicalState)</span> <span>@Html.ValidationMessageFor(model => model.TechnicalStateDescription)</span>
</td>
</tr>
EDIT1：使用此方法在控制器中初始化：
public static List<SelectListItem> CreateDefaultStateList(int? selected = -1)
{
List<SelectListItem> sl = new List<SelectListItem>();
for (int i = -1; i < 5; i++)
{
SelectListItem sli = new SelectListItem();
if (i == 0 || i == -1)
sli.Text = "";
else
sli.Text = i.ToString();
sli.Value = i.ToString();
if (i == selected)
sli.Selected = true;
sl.Add(sli);
}
return sl;
}
EDIT2：创建控制器。defaultstatelist 是从上面发布的方法返回的内容。
List<SelectListItem> defaultStateList = CreateDefaultStateList();
[Authorize]
public ActionResult Create()
{
FillViewBag();
ViewBag.PropX = defaultStateList;
ViewBag.TiresFront = defaultStateList;
ViewBag.TechState = defaultStateList;
ViewBag.PropY= defaultStateList;
ViewBag.PropZ= defaultStateList;
ViewBag.PropA= defaultStateList;
ViewBag.PropB= defaultStateList;
ViewBag.PropC= defaultStateList;
ViewBag.PropD= defaultStateList;
return View();
}
输入这个我注意到方法中的默认值。可能是这样... ==> 试过了，不是吗。现在将代码更新为“-1”作为默认值。
