Question

我正在使用带有剑道的MVC。单击kendo网格的添加按钮即会打开一个弹出对话框。模态对话框包含一个包含两个组合框的字段。当用户在这些字段中输入值并单击添加按钮时，我会填充Viewmodel。我使用GetLanguages（）和GetCountries（）操作方法填充组合框。因此，使用viewmodel不会填充这两个combox。我在视图中设置了viewmodel的模型字段。例如

@using System.Collections
@model CC.GRP.MCRequest.ViewModels.UserProfileViewModel
@(Html.Kendo().ComboBoxFor(model => model.DefaultLanguageCode)

选择组合框并不会将值添加到viewmodel。如果我做错了，有人可以告诉我。我是否需要在视图模型中添加国家/地区列表集，并在将其发送到视图之前在控制器内的viewmodel中填充集合。如果是这样的话，我该怎么做。以下是我的代码

        <div class="editor-label">
            @Html.LabelFor(model => model.Forename)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Forename)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Surname)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Surname)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.PreferredName)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.PreferredName)
        </div>

      <div class="editor-field">
    @(Html.Kendo().ComboBoxFor(model => model.DefaultLanguageCode)
     //   .Name("LanguageCode")
        .HtmlAttributes(new { style = "width:300px" })
        .DataTextField("LanguageName")
        .DataValueField("DefaultLanguageCode")
        .DataSource(dataSource => dataSource
        .Read(read => read.Action("GetLanguages", "Admin").Type(HttpVerbs.Post))
        )
    )
</div>
<div class="editor-label">
    @Html.LabelFor(model => model.DefaultCountryCode)
</div>
<div class="editor-field">
    @(Html.Kendo().ComboBoxFor(model => model.DefaultCountryCode)
     //   .Name("CountryCode")
        .HtmlAttributes(new { style = "width:300px" })
        .DataTextField("Country")
        .DataValueField("DefaultCountryCode")
        .DataSource(dataSource => dataSource
        .Read(read => read.Action("GetCountries", "Admin").Type(HttpVerbs.Post))
        )
    )
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.TimeZoneName)
</div>
<div class="editor-field">
    @(Html.Kendo().ComboBoxFor(model => model.TimeZoneName)
     //   .Name("TimeZoneID")
        .HtmlAttributes(new { style = "width:300px" })
        .DataTextField("TimeZoneName")
        .DataValueField("TimeZoneID")
        .DataSource(dataSource => dataSource
        .Read(read => read.Action("GetTimeZones", "Admin").Type(HttpVerbs.Post))
        )
    )
</div>

尝试删除放在组合框中的名称，它可能会阻止 DefaultLanguageCode 正确映射到viewModel属性，因为你调用了combobox LanguageDD 。

@(Html.Kendo().ComboBoxFor(model => model.DefaultLanguageCode)
        //.Name("LanguageDD") <-- here
        .HtmlAttributes(new { style = "width:300px" })
        .DataTextField("LanguageName")
        .DataValueField("LanguageCode")
        .DataSource(dataSource => dataSource
        .Read(read => read.Action("GetLanguages", "Admin").Type(HttpVerbs.Post))
        )
    )

选择的组合框的值不添加到视图模型
