Question

我想从数据库中输入一个值，因为我的下拉列表已经有一个与文本相同的值，所以我想要一个与我的文本分开或不同的值。示例代码= 1，text =病理学家。

我的控制器：

public ActionResult MainHistopathologyForm(string id)
{
    var patientprofileViewModel = new MDHPIStables();
    patientprofileViewModel.histopathology = db.histopathology.Find(id);
    patientprofileViewModel.roles = db.roles.Find(Session["role"]);
    var PathologistList = new List<string>();

    var PathologistQry = from d in db.pathologist
                   select d.pathologist;

    PathologistList.AddRange(PathologistQry.Distinct());
    TempData["pathologistlist"] = new SelectList(PathologistList);

    return View(patientprofileViewModel);
}

MainHistopathologyForm.cshtml：

@Html.Partial("RolesHistopathologyForm", Model.roles, new ViewDataDictionary())


@Html.Partial("Partial_HistopathologyForm", Model.histopathology,
 new ViewDataDictionary())

Partial_HistopathologyForm：

@{
    ViewBag.concurring1 = TempData["pathologistlist"];
 }                            
@Html.DropDownList("concurring1", "Select Pathologist")

Answer 1

@ Html.DropDownList（＆＃34;您的ViewBag名称＆＃34;，null，＆＃34;选择列表＆＃34;，新{@class =＆＃34;表单控件＆＃34;，required =＆＃34;必需＆＃34;}）
