将最近创建的id从Action传递到部分视图（ASP.NET MVC）

c#htmlasp.netasp.net-mvcentity-framework
3

我有一个遇到困难的小问题。我有两个表：tbl_NIR和tbl_I_O，tbl_I_O有一个外键NirID，所以我知道是哪个nir得到了这个i_o。

我有一个添加（Add）和查看（View）操作，在那里我将nir数据插入数据库。添加操作返回PartialView。在这个PartialView中，我有一个新的tbl_I_O视图。

我需要以某种方式获取最后插入的ID，在我执行添加操作后我应该以某种方式获取它。如何将ID从添加操作传递到tbl_I_O部分视图？我查看过这个链接和其他链接，但没有成功："Asp.Net mvc - pass last created id from action to partial view"。

动作：

[HttpPost]
public ActionResult Add(BOL1.tbl_NIR nir)
    {
        try
        {
            if (ModelState.IsValid)
            {
                db.tbl_NIR.Add(nir);
                db.SaveChanges();
                //var ni = db.tbl_NIR.OrderByDescending(x => x.ID).FirstOrDefault().ID;
                 TempData["Msg"] = "Created Successfully!";
                return RedirectToAction("AddIO", nir);
                //return RedirectToAction("AddIO", new { id = ni });
                //return RedirectToAction("AddIO", "AddIO", new { id = ni });
            }
            return View(nir);

另外一个：

[HttpGet]
    public ActionResult AddIO()
    {
        //var ni = db.tbl_I_O.OrderByDescending(x => x.NirID).FirstOrDefault().NirID;
        //return View(ni);
        return View();
    }



[HttpPost]
    public ActionResult AddIO(BOL1.tbl_I_O oi)
    //public ActionResult AddIO(BOL1.tbl_I_O oi, int ID)
    {
        try
        {
            if (ModelState.IsValid)
            {
                db.tbl_I_O.Add(oi);
                db.SaveChanges();
                TempData["Msg"] = "Created Successfully!";
                return RedirectToAction("Index");
            }
          return View(oi);
        }

这是我的代码视图中需要展示从tbl_NIR（操作Add）插入的最后一个ID到tbl_I_O（操作AddIO部分视图）的部分：

 <div class="form-group">
                @Html.LabelFor(model => model.NirID, "Nir ID", htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @*@Html.DropDownList("NirID", null, htmlAttributes: new { @class = "form-control" })*@
                    @Html.EditorFor(model => model.NirID, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.NirID, "", new { @class = "text-danger" })
                </div>
</div>

非常感谢您的帮助。对于可能存在的错别字，我表示抱歉！

基本上，我需要的是，在为 tbl_NIR 创建新行时（例如：ID = 23 (自动递增)，等等），ID 的值（“23”）显示在部分视图上：

@Html.EditorFor(model => model.NirID, new { htmlAttributes = new { @class = "form-control" } })

字段。我认为可能是“EdidorFor是问题”！？

你的 PartialView 在哪里？ - Mihai Alexandru-Ionut

您不能重定向到PartialView。

[HttpPost]
public ActionResult Add(BOL1.tbl_NIR nir)
{
        if (ModelState.IsValid)
        {
            db.tbl_NIR.Add(nir);
            db.SaveChanges();
            Session["id"]=nir.ID;
            return RedirectToAction("AddIO");
        }
    return View(nir);
}

C# - 传递一个新的 BOL1.tbl_I_O 对象。

[HttpGet]
public ActionResult AddIO()
{
    return View(new BOL1.tbl_I_O());
}

HTML

更改

@Html.EditorFor(model => model.NirID, new { htmlAttributes = new { @class = "form-control" } })

To

<input type="text" id="NirID" name="NirID" class="form-control" value="@Session["id"]"/>
