Question

我有两个DDL

创建视图

＆＃13;

<div class="form-group">
  @Html.LabelFor(model => model.Stage, "Stage", new { @class = "control-label col-md-5" })
  <div class="col-md-offset-0">
    @Html.DropDownList("Stage", String.Empty) @Html.ValidationMessageFor(model => model.Stage)
  </div>
</div>


<div class="form-group">
  @Html.LabelFor(model => model.InternalApprovalAuthorities, "Internal Approval Authority", new { @class = "control-label col-md-8" })
  <div class="col-md-offset-1">
    @Html.DropDownList("InternalApprovalAuthorities", string.Empty) @Html.ValidationMessageFor(model => model.InternalApprovalAuthorities)
  </div>
</div>

＆＃13;

在我的编辑视图中，我只想查看它们显示的信息。

修改视图

<div class="form-group">
    @Html.LabelFor(model => model.Stage, "Stage", new { @class = "control-label col-md-5" })
    <div class="col-md-offset-0">
       @ViewBag.StageText
       @Html.HiddenFor(model => model.Stage)
     </div>
</div>

<div class="form-group">
    @Html.LabelFor(model => model.InternalApprovalAuthorities, "Internal Approval Authority", new { @class = "control-label col-md-5"})
    <div class="col-md-offset-0">
        @*@Html.Display("InternalApprovalAuthorities")*@
        @ViewBag.InternalApprovalAuthoritiesText
        @Html.HiddenFor(model => model.InternalApprovalAuthorities)
    </div>
</div>

控制器 -

此代码位于我的Get Create

中

＆＃13;

ViewBag.InternalApprovalAuthorities = new SelectList(db.InternalApprovalAuthorities, "InternalApprovalAuthoritiesID", "InternalApprovalAuthoritiesText");

＆＃13;

此代码位于我的用户编辑视图的获取和发布中

Stage stage = db.Stages.Where(t => t.StageID == imsregister.Stage).FirstOrDefault();
ViewBag.StageText = stage.StageText;

InternalApprovalAuthority internalapprovalauthorities = db.InternalApprovalAuthorities.Where(a => a.InternalApprovalAuthoritiesID == imsregister.InternalApprovalAuthorities).FirstOrDefault();
if(internalapprovalauthorities != null)
{
    ViewBag.InternalApprovalAuthority = internalapprovalauthorities.InternalApprovalAuthoritiesText;
}

两者都以相同的方式构建。但是Stage返回我需要的文本值。如果我使用@ViewBag.InternalApprovalAuthorities，则InternalApprovalAuthorities不会返回任何内容，如果我使用Display("InternalApprovalAuthorities")，则返回int值而不是text。

关于这个问题的任何想法？

Answer 1

我的问题是我遇到了冲突，因为我的班级名为InternalApprovalAuthority，而我的ViewBag名称相同。为了解决这个问题，我所做的就是在视图和控制器中重命名ViewBag，从而为我提供我想要的文本值。

修改视图

<div class="form-group">
  @Html.LabelFor(model => model.InternalApprovalAuthorities, "Internal Approval Authority", new { @class = "control-label col-md-5"})
  <div class="col-md-offset-0">
    @ViewBag.IAA @Html.HiddenFor(model => model.InternalApprovalAuthorities)
  </div>
</div>

控制器GET和POST

       InternalApprovalAuthority internalapprovalauthorities = db.InternalApprovalAuthorities.Where(a => a.InternalApprovalAuthoritiesID == imsregister.InternalApprovalAuthorities).FirstOrDefault(); 
       if (internalapprovalauthorities != null) 
        { 
           ViewBag.IAA = internalapprovalauthorities.InternalApprovalAuthoritiesText;
        }

DropdownList返回int值而不是text
