Asp.net 使用Ajax.begin通知ViewModel post为空

我的ajax表单有问题： 我有这个密码

@using (Ajax.BeginForm("Search", "SyntheseEvt",
                                            FormMethod.Post,
                                            new AjaxOptions
                                            {
                                                InsertionMode = InsertionMode.Replace,
                                                HttpMethod = "POST",
                                                UpdateTargetId = "search-results"
                                            }
                                            ))

        {
        <div class="row">
        @{
         CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;


        <div class="col-md-4">
            <div class="dx-field-label">@Resources.Resource.DDebut</div>
            <div class="dx-field-value">
                @(Html.DevExtreme().DateBox()
                        .ID("DtDebut")
                        .Type(DateBoxType.Date)
                        .Value(Model.paramSynthese.DtDebut_c)
                    .DisplayFormat(currentCulture.DateTimeFormat.ShortDatePattern)
                )

但我的搜索视图模型中的所有内容都为空

我认为这是关于devextreme html元素的。

我正在尝试将嵌套模型paramsyntheveviewmodel绑定到控制器中的post操作——

有人知道吗？

嘿，伙计们，我解决了这个问题：我的子模型缺少get/set属性

表单控件的

name

属性必须与模型中属性的名称匹配。它甚至不清楚你想绑定什么，甚至不知道视图中的模型是什么！如果它是searchsyntheevtviewmodel，则不会绑定任何内容，因为它甚至没有任何属性，只有

DefaultModelBinder

无法在视图中设置模型的字段是父模型@model searchsyntheevtviewmodel我正在尝试将嵌套模型paramsyntheevtviewmodel绑定到控制器中的post操作阅读我以前的注释！您不能绑定到字段，输入的

name

属性必须是

name=“paramSynthese.dtc”
