asp.net-mvc – 如何将Telerik ComboBox中的数据绑定到我的数据

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
        @Html.ValidationMessageFor(model => model.Name)
    </div>
    <div class="editor-field">
    @(Html.Telerik().ComboBoxFor(model => model.VendorId)
        .Name("ddlVendor")
        .ClientEvents(events =>
                          {
                              events.OnLoad("onVendorLoad");
                              //events.OnChange("onVendorChange");
                              events.OnDataBinding("onComboBoxDataBinding");
                          }
        )
        .DataBinding(bind => bind.Ajax().Select("_AjaxGetVendors","Car"))
    )
    </div>
    <p>
        <input type="submit" value="Зберегти" />
    </p>
</fieldset>}

在我的控制器中,我获得了实体,但VendorId == 0.

[HttpPost]
    public ActionResult Create(Car obj)
    {
            dm.InsertModel(obj);
            return RedirectToAction("Create");
    }
