仅更新部分视图

Question

我正在尝试提交局部视图，激活局部视图验证并加载主视图（主视图将不会一直相同）。基本上，我只想更新局部视图而不影响主视图视图。现在，当我提交局部视图时，它会加载局部视图操作。

部分视图：

@using (Ajax.BeginForm("LeaveReply", "Contactus", new AjaxOptions {  InsertionMode = InsertionMode.Replace,    UpdateTargetId = "respond"))
{
                        <h3>Leave a reply</h3>

                            <p class="textarea-block">  
                                <label><span>Message (required)</span></label>                      
                                @Html.ValidationMessageFor(o=>o.Message)
                                @Html.TextAreaFor(o => o.Message, new { @rows="6", @cols="80", @name="message",@class="form-control" })
                            </p>
                            <p class="input-block clearfix">
                               <label class="required"><span>Your Name (required)</span></label> 
                                @Html.ValidationMessageFor(o=>o.Name)
                                @Html.TextBoxFor(o=>o.Name, new { @class="form-control" })
                            </p>
                            <p class="input-block">
                                <label class="required"><span>Email (required)</span></label> 
                                @Html.ValidationMessageFor(o=>o.Email)
                                @Html.TextBoxFor(o=>o.Email, new { @class="form-control" })
                            </p>
                            <p class="input-block last">
                                 <label class="required"><span>Website</span></label> 
                                @Html.ValidationMessageFor(o=>o.WebSite)
                                @Html.TextBoxFor(o=>o.WebSite, new { @class="form-control" })
                            </p>
                            <div class="clear"></div>                            
                            <p class="contact-button clearfix">                    
                                <input type="submit" id="submit-contact" value="Submit">

                            </p>   
                       <div class="clearfix"><br /></div>
                            <div class="kp-success">@ViewBag.Message</div>                     

                        <div id="response"></div>

       }

主要观点：

<div id="respond" class="kopa-border-2">
  @{Html.RenderPartial("_MessagePartial", new Classified.ViewModels.MessageViewModel());}
</div>

联系我们控制器

[HttpPost]
public PartialViewResult LeaveReply(MessageViewModel model)
  {
       JsonResult result = new JsonResult();
       if (ModelState.IsValid)
        {

        }

       return PartialView("_MessagePartial", model);
   }

型号：

public class MessageViewModel
    {
        [Key]
        public int ID { get; set; }
        public string MessageType { get; set; }
        [Required]
        public string Name { get; set; }
        [EmailAddress]
        [Required]
        public string Email { get; set; }
        public string WebSite { get; set; }
        [Required]
        public string Message { get; set; }
        public DateTime? AddedDateTime { get; set; }
        public int? UserID { get; set; }
    }

*主视图绑定到不同的模型。
