ASP.NET MVC 2加载部分视图使用jQuery – 没有客户端验证

$('#sizeAddHolder').load(
                '/MyController/MyAction',function () { ... });

我的控制器中的操作代码如下：

public ActionResult MyAction(byte id)
    {
        var model = new MyModel
        {
            ObjectProp1 = "Some text"
        };

        return View(model);
    }

    [HttpPost]
    public ActionResult MyAction(byte id,FormCollection form)
    {
        // TODO: DB insert logic goes here

        var result = ...;

        return Json(result);
    }

我返回的部分视图看起来像这样：

<% using (Html.BeginForm("MyAction","MyController")) {%>
    <%= Html.ValidationSummary(true) %>

    <h3>Create my object</h3>

    <fieldset>
        <legend>Fields</legend>

        <div class="editor-label">
            <%= Html.LabelFor(model => model.ObjectProp1) %>
        </div>
        <div class="editor-field">
            <%= Html.TextBoxFor(model => model.Size.ObjectProp1) %>
            <%= Html.ValidationMessageFor(model => model.ObjectProp1) %>
        </div>

        div class="editor-label">
            <%= Html.LabelFor(model => model.ObjectProp2) %>
        </div>
        <div class="editor-field">
            <%= Html.TextBoxFor(model => model.ObjectProp2) %>
            <%= Html.ValidationMessageFor(model => model.ObjectProp2) %>
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>

<% } %>

在这种情况下,客户端验证不起作用.包含验证消息的脚本还不包括在返回的视图中.我的模型类中的两个属性都有Required和StringLength属性.
有没有办法在已经加载的视图中触发客户端验证？
