IEnumerable<SelectListItem> ColumnList = from ainCompany.Column.ToList()                                         where a.parentID==0                                         selectnewSelectListItem                                         {                                             Value = a.ColumnID.ToString(),                                             Text = a.name                                         };List<SelectListItem> Items =newList<SelectListItem>();Items.Add(newSelectListItem { Value ="0", Text ="一级栏目"});Items.AddRange(ColumnList);ViewBag.ColumnList = Items;。。。。 ***直接使用后台ViewBag: @Html.DropDownList("groupid", new SelectList((IEnumerable<SelectListItem>)ViewBag.GroupList, "groupid", "groupname")); ***添加静态数据项：@Html.DropDownListFor(model => model.GroupCategoryID,new SelectListItem[] { new SelectListItem { Text = "小学", Value = "1" }, new SelectListItem { Text = "中学", Value = "2" } })5.在页面中输出javascript变量值：<script language="JavaScript" type="text/javascript">         var teacher = @Html.Raw(HttpUtility.HtmlDecode(teacherStr.ToString()));

@helper Printtab (Tab tab, BOOL active)
{
if (active)
{
<li class= "Active" >
<a href= "@tab. Url "> @tab. Text</a>

@if (tab. closable)
{
<span class= "Button-tab-close" >&times;</span>

using (Html.BeginForm ("Close", "tab", FormMethod.Post, new {id = "Closetab"})
