在MVC中Controller为VIEW页面中的DropDownList赋值并锁定

首先是枚举对象的遍历

#region 类型列表框
            typeitems = new List<SelectListItem>();
            foreach (string i in Enum.GetNames(typeof(ServiceDocumentType)))
            {

typeitems.Add(new SelectListItem { Text = ((ServiceDocumentType)

Enum.Parse(typeof(ServiceDocumentType), i)).GetDescription(),

Value = ((int)((ServiceDocumentType)

Enum.Parse(typeof(ServiceDocumentType), i))).ToString() });

            }
            #endregion
当有了上面基础后,再根据传入到当前实体,锁定当然选中的项
 ServiceDocumentCreateModel model = new ServiceDocumentCreateModel
            {
                ProductID = entity.ProductID,
                Content = entity.Content,
                DownloadUrl = entity.DownloadUrl,
                ImageUrl = entity.ImageUrl,
                Level = entity.Level,
                LinkUrl = entity.LinkUrl,
                Title = entity.Title,
                Type = new SelectList(typeitems, "Value", "Text", (int)entity.Type),
                Status = new SelectList(statusItems, "Value", "Text", (int)entity.Status),
            };
其中Type和Status都是SelectList类型,这样方便前台Model在VIEW中的展示。
前台中展示就一句搞定:
  <%=Html.DropDownList("Type",Model.Type)%>
