如何在重新加载后将数据传递到部分视图

在控制器中，您使用ViewBag来设置自定义值，但在视图中，您正在使用ViewData以及引用不同的名称（您在控制器中设置 ViewBag 的时间属性，但您希望视图中使用 ViewData 的 vb 属性）。

更改视图以期望模型"：

@model MyModel
@{
    string time = "";
    if (ViewData["Time"] != null) 
    {
       time = ViewData["Time"];
    } 
}
<div>
    <span>@Model.Time</span>
</div>

并更改您的控制器以传递它：

public ActionResult ReloadTest1()
{
    var model = new MyModel {Time = DateTime.Now.ToString()};
    return View(model);
}
public PartialViewResult ReloadTest1Partial()
{
    var model = new MyModel {Time = DateTime.Now.ToString()};
    return PartialView(model);
}

您的主视图文件将如下所示：

@model MyModel
<div id="myPartialViewContainer">
    @{Html.RenderPartial("_ReloadTest1Partial", model);}
</div>

并创建您的模型：

public class MyModel
{
    public string Time {get;set;}
}

另一方面，最好使用强类型model而不是ViewBag或ViewData，因为您可能会遇到编译错误和智能感知

最终解决方案：

控制器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;
namespace RolloutTool.Controllers
{
    [OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
    public class ExperimentalController : Controller
    {
        public ActionResult ReloadTest1()
        {
            var model = new RolloutTool.Models.ExperimentalViewModels.MyModel { Time = DateTime.Now.ToString() };
            string temp = DateTime.Now.ToString();
            ViewBag.Time = temp;
            ViewData["Time"] = temp;
            return View(model);
        }
        [HttpPost]
        public PartialViewResult ReloadTest1Partial(string test)
        {
            var model = new RolloutTool.Models.ExperimentalViewModels.MyModel { Time = DateTime.Now.ToString() };
            string temp = DateTime.Now.ToString();
            ViewBag.Time = temp;
            ViewData["Time"] = temp;
            return PartialView("_ReloadTest1Partial", model);
        }
        
        // GET: Experimental
        public ActionResult Experimental()
        {
            ViewBag.Message = "Your contact page.";
            ViewBag.TestValue = 10;
            string[] temp = { "alpha", "beta", "gamma", "delta" };
            ViewBag.names = temp;
            int temp2 = temp.Length;
            ViewBag.nameslength = temp2;
            return View();
        }
    }
}

视图：

@{
    ViewBag.Title = "ReloadTest1";
    string time = this.ViewBag.Time;
    ViewData["date"] = time;
    ViewBag.TheTitle = "test";
}

@{
    string time = "";
    string temp = "";
    if (ViewData["vb"] != null)

这将正确更新部分视图并重新加载所选选择下拉列表。（请参阅样式和脚本在分部视图中不起作用）
