asp.net-mvc-3 – asp.net mvc 3.0客户端验证无效

@using (Ajax.BeginForm("SaveLayout",new AjaxOptions { HttpMethod = "Post"}))
{
@Html.ValidationSummary(true)
<div style="padding: 10px;">
    <div class="editor-field">
        Layout Name: @Html.EditorFor(m => m.Name)
        @Html.ValidationMessageFor(m => m.Name)</div>
    <br />
    <br />
    <input type="submit" value="Save" />
    <input type="button" onclick="CloseDialog()" value="Cancel" />
</div>
}

?在我的_Layout.cshtml看起来像这样 –

<script src="@Url.Content("~/Scripts/JQuery/jquery-1.6.4.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/JQuery/jquery-ui.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/JQuery/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/JQuery/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/JQuery/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

我在我的根web.config中有这个 –

<add key="ClientValidationEnabled" value="true"/> 
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>

这就是我的控制器动作的样子 –

[HttpPost]
public ActionResult SaveLayout(Model.Layout layout)
{
    if (ModelState.IsValid)
    {
        ILayout.SaveLayout(layout);
    }
    return PartialView("_SaveLayout",layout);
}

而鲁莽这是我的模特 –

public class Layout : BaseModel
{
    [Required(ErrorMessage = "Please assign name to the compare group.")]
    public string Name { get; set; }
}

当名称字段为空且用户点击保存按钮时,我无法使客户端验证工作.有人可以建议我在这里做错了什么吗？任何帮助都会受到高度赞赏.
