Question

名称和ID存储在数据库中。我想显示从数据库到ViewPage下拉列表的所有名称和ID。这里我只在下拉列表中显示了Name列。是否有可能在单个下拉列表中显示两列？请让我知道解决方案。

控制器：

var Employe = (from table in dc.tbl_EmployeeDetails
               select table.Employee_Name).ToList();
ViewData["empName"] = Employe ;

var department = (from table in dc.tbl_EmployeeDetails
                  select table.Department).ToList();
ViewData["dept"] = department;

查看

<select id="reportto" disabled="disabled" font-size:14px">
    @foreach(var person in ViewData["empName"] as List<string>)
    {
        if(@Model.employee!=@person)
        {
           <option>@person</option>
        }
    }
</select>

这里我只在下拉列表中显示了名称。如何在单个下拉列表中显示名称和部门？

请做一件事。

请使用SelectListItem作为绑定下拉列表。

List<SelectListItem> lstLocation = new List<SelectListItem>();

SqlParameter[] parameters = { new SqlParameter("@ID", ID),new 
SqlParameter("@Name",Name)};

DataSet dsLocation = SqlHelper.ExecuteDataset(CommandType.StoredProcedure, "GetPersonalInfo", parameters);

   if (dsLocation != null && dsLocation.Tables.Count > 0 && dsLocation.Tables[0].Rows.Count > 0)
            {
                lstLocation = (from drLocation in dsLocation.Tables[0].AsEnumerable()
                               select new SelectListItem { Text = `drLocation["PersonID"].ToString() + ' - '+ drLocation["PersonName"].ToString(), Value = drLocation["PersonID"].ToString() }).ToList();`
            }

并将此列表obejct存储到view bag并在视图中设置为Dropdownlist。

ViewBag.Location=lstLocation ;

@Html.DropDownList("Location", ViewBag.Location as List<SelectListItem>,
 "-SELECT-", new { data_val = "true", data_val_required = "Please select 
 location", @class = "form-control" })

使用上面的代码，您的数据将在下拉列表中显示为“1-ROnak”，“2-Manish”。选择后，您可以使用“ - ”分割拆分名称和ID。

谢谢。

在控制器中：

ViewBag.EmployeeDetails= db.EmployeeDetails.ToList();

在视图中：

@model ...
@{
        ViewBag.Title ="Employe ";
        List<Proyect.Models.EmployeeDetails> Details = ViewBag.EmployeeDetails;
}

<select name="EmployeeDetails" class="form-control" id="EmployeeDetails">
            <option>Select one</option>
            @foreach (var Detail  in Details)
            {
            <option id="@Docs.Id_Employee_Detail" value="@Docs.Id_Employee_Detail">@Detail.Name : @Detail.Department</option>
            }
</select>

并在控制器中收到参数

public ActionResult Something(int EmployeeDetails)
{
var EmployeeDetailSelected = dc.tbl_EmployeeDetails.Find(EmployeeDetails);
}

在Razor下拉列表中显示两个列值？或者Html下拉列表？
