Question

有没有办法调用一些泛型函数，告诉我下拉列表的值：我将隐藏这个oldStatusID。所以，正如你在我的数据库中看到的那样：

JobstatusID |状态名称 4 |展望/等待提案

当我更改状态时，例如“Lost”，然后单击“保存”，程序保持id = 4，而不是id = 2 ..

以下是我的观点：

@using System.Collections.Concurrent
@model DataAccess.PartialClass.StatusPipelineMerge
@{
ViewBag.Title = "Edit";
}

<h2>Edit</h2>

@using (Html.BeginForm())

这是我的控制器 - 编辑（获取和发布）

        //ViewBag.EventTypeID = new SelectList(db.EventTypes, "EventTypeID", "Event", merge.EventTypeID);

所以，我尝试使用Status2 ViewBag，为文本/字符串提取id。谢谢！
