ViewBag的简单使用
一,在控制器中写好数据绑定
//通过ID查找出整列的数据
Case.Models.Case theCase = db.Case.Find(id);
ViewBag.CaseUser2 = theCase;
二,在视图中
实例化一个变量
@{
ViewBag.Title = "Edit";
var thecase = ViewBag.CaseUser2 as Case.Models.Case;
}
三,则可以用ViewBag将里面的每一列数据选出来判断
@if (thecase.CaseUser2 == "" )
{
<div class="form-group">
@Html.LabelFor(model => model.CaseUser2, new { @class = "control-label col-md-2", style = "padding-top: 6px;" })
<div class="col-md-10">
@Html.DropDownList("CaseUser2", (SelectList)ViewData["CaseUserList2"], new { @class = "selectpicker", @data_style = "btn-default" })
@Html.ValidationMessageFor(model => model.CaseUser2)
</div>
</div>
}
