c# - 修改的布尔值未从复杂绑定模型传入控制器方法

Question

我正在尝试为应用程序的一部分构建搜索引擎，我需要帮助。我正在使用 MVC 4，但我不知道为什么我的 checkboxfor 总是返回“true”值。

我正在使用这些不同的项目：

一、搜索模型：

public class SearchBackstoreInventoryPartial
{
    [RegularExpression(@"^[a-zA-Z0-9\',;/\)\(\-\. ]*$", ErrorMessage = "Input is invalid.")]
    public string mCardName { get; set; }

    public decimal mBackstorePrice { get; set; }
    public string mBackstorePriceSymbol { get; set; }

    public int mBackstoreQty { get; set; }
    public string mBackstoreQtySymbol { get; set; }

    public int mBackstoreSoldQty { get; set; }
    public string mBackstoreSoldSymbol { get; set; }

    public decimal mBackstoreDiscount { get; set; }
    public string mBackstoreDiscountSymbol { get; set; }

    public IEnumerable<SelectListItem> mSymbolList { get; set; }

    public List<StoreViewModel> mListStores = new List<StoreViewModel>();

    private readonly StoresManager mStoresManager = new StoresManager();

    public SearchBackstoreInventoryPartial()
    {
        mSymbolList = new SelectList(ValueDomain.LIST_METHODS);

        List<StoreInfo> listStores = mStoresManager.ListStores();

        foreach (StoreViewModel itemToAdd in listStores.Select(_store => new StoreViewModel
            {
                mStore = _store,
                mIsSelected = true
            }))
        {
            mListStores.Add(itemToAdd);
        }
    }

您几乎可以忽略那里的所有内容，我主要关注public List<StoreViewModel> mListStores = new List<StoreViewModel>();对象。AStoreViewModel是这种对象：

public class StoreViewModel
{
    public StoreInfo mStore { get; set; }

    public bool mIsSelected { get; set; }
}

因此，基本上，对于我的应用程序拥有的每个商店，我都将其存储起来，并将 mIsSelected 放到true.

然后我渲染一个这样的页面：

@model MvcMagicAdmin.Utilities.SearchModels.SearchBackstoreInventoryPartial

@using(Html.BeginForm())
{
    <div class="formStyle defaultBaseStyle baseFontSize">
        <div class="center">
            <div>
                <div class="float-left">Stores:</div>
                <div class="float-right">
                    @for (int i = 0; i < Model.mListStores.Count; i++)
                    {
                        <div class="float-left"style="padding: 1px; margin: 1px">
                            @Model.mListStores[i].mStore.mStoreName
                        </div>
                        <div class="float-right"style="padding: 1px; margin: 1px">
                            @Html.CheckBoxFor(_item => _item.mListStores[i].mIsSelected)
                        </div>
                        <div class="clear"></div>
                    }
                </div>
                <div class="clear"></div>
            </div>

            <div>
                <div class="float-left">
                    Card Name:
                </div>
                <div class="float-right">
                    @Html.TextBoxFor(_item => _item.mCardName)
                    @Html.ValidationMessageFor(_item => _item.mCardName)
                </div>
                <div class="clear"></div>
            </div>
            <div>
                <div class="float-left">
                    Backstore Item Price
                </div>
                <div class="float-right">
                    @Html.DropDownListFor(_item => _item.mBackstorePriceSymbol, Model.mSymbolList, "---Select a value---")
                    @Html.TextBoxFor(_item => _item.mBackstorePrice, new { @class = "positive" } )
                </div>
                <div class="clear"></div>
            </div>
            <div>
                <div class="float-left">
                    Backstore Quantity in stock
                </div>
                <div class="float-right">
                    @Html.DropDownListFor(_item => _item.mBackstoreQtySymbol, Model.mSymbolList, "---Select a value---")
                    @Html.TextBoxFor(_item => _item.mBackstoreQty, new { @class = "positive-integer" } )
                </div>
                <div class="clear"></div>
            </div>
            <div>
                <div class="float-left">
                    Backstore Item sold
                </div>
                <div class="float-right">
                    @Html.DropDownListFor(_item => _item.mBackstoreSoldSymbol, Model.mSymbolList, "---Select a value---")
                    @Html.TextBoxFor(_item => _item.mBackstoreSoldQty, new { @class = "positive-integer"})
                </div>
                <div class="clear"></div>
            </div>
            <div>
                <div class="float-left">
                    Backstore Item discount
                </div>
                <div class="float-right">
                    @Html.DropDownListFor(_item => _item.mBackstoreDiscountSymbol, Model.mSymbolList, "---Select a value---")
                    @Html.TextBoxFor(_item => _item.mBackstoreDiscount, new { @class = "positive"})
                </div>
                <div class="clear"></div>
            </div>
        </div>
        <input type="submit" value="Go" class="buttonField"/>
        <div class="clear"></div>
    </div>
}

然后，我的控制器方法：

[HttpPost]
public ActionResult SearchBackstoreInventory(SearchBackstoreInventoryPartial _searchBackstore)
{
    // Do some work here...
}

默认情况下选中复选框，但尽管我取消选中它们，但该值仍为 true。谁能帮我弄清楚为什么这不起作用？

这是我认为循环的渲染：

    <div class="float-right">
        <div class="float-left"style="padding: 1px; margin: 1px">
            FinePlaySet.com
        </div>
        <div class="float-right"style="padding: 1px; margin: 1px">
            <input checked="checked" id="mListStores_0__mIsSelected" name="mListStores[0].mIsSelected" type="checkbox" value="true" /><input name="mListStores[0].mIsSelected" type="hidden" value="false" />
        </div>
        <div class="clear"></div>
        <div class="float-left"style="padding: 1px; margin: 1px">
            EbayAuctions
        </div>
        <div class="float-right"style="padding: 1px; margin: 1px">
            <input checked="checked" id="mListStores_1__mIsSelected" name="mListStores[1].mIsSelected" type="checkbox" value="true" /><input name="mListStores[1].mIsSelected" type="hidden" value="false" />
        </div>
        <div class="clear"></div>
        <div class="float-left"style="padding: 1px; margin: 1px">
            Strawberry Fields
        </div>
        <div class="float-right"style="padding: 1px; margin: 1px">
            <input checked="checked" id="mListStores_2__mIsSelected" name="mListStores[2].mIsSelected" type="checkbox" value="true" /><input name="mListStores[2].mIsSelected" type="hidden" value="false" />
        </div>
        <div class="clear"></div>
</div>

我尝试过以不同的方式构建模型，如下所示：

public bool mFinePlaySet { get; set; }

public bool mEbayAuctions { get; set; }

所以，是的，我没有使用构建视图模型列表的方法，而是为我拥有的每个商店创建了单个布尔值。所以基本上我的视图现在呈现如下：

<div>
    <div class="float-left">Stores:</div>
    <div class="float-right">
        <p>FinePlaySet.com : @Html.CheckBoxFor(_item => _item.mFinePlaySet)</p>
        <p>eBay Auctions: @Html.CheckBoxFor(_item => _item.mEbayAuctions)</p>
    </div>
    <div class="clear"></div>
</div>

而且我确实得到了正确的检查值，但它很难看，每次我有一个新商店时我都需要去修改它。所以，基本上，我的问题仍然没有答案......
