easyui和Ajax在mvc3中的权限设置

权限管理，ps：抄的领导的，比较粗糙，一切挺好的，就是没有那个编辑用户权限时，默认选中原来已有的权限节点。

效果如下：

cshtml代码：

 1 @{
 2     ViewBag.Title = "学校后台权限设置";
 3     Layout = "~/Views/Shared/_Layout2.cshtml";
 4 }
 5 @section Head{
 6     <script src="@Url.Content("~/Scripts/BasicSchool_RightJS.js")" type="text/javascript"></script>
 7     <script type="text/javascript">
 8         $(function () {
 9             $("#provinceId").combobox({
10                 url: "/BasicSchool_Right/GetTeacher",
11                 editable: false,
12                 valueField: "id",
13                 textField: "userName",
14                 panelHeight: "auto"
15             });
16
17         });
18     </script>
19 }

BLLBasicMainTreeView.cs

方法：

private void GetTree(int parentID, BasicMainTreeView moParent)
{
List<BasicMainTreeView> modelInfo = models.Where(Model => Model.parentID == parentID).ToList();
foreach (BasicMainTreeView model in modelInfo)
{
BasicMainTreeView mo = new BasicMainTreeView();
mo = model;
moParent.children.Add(mo);
GetTree(mo.id, mo);
}
}里的 models.Where(Model => Model.parentID == parentID).ToList();刚开始挺让我费解的[ps：我太笨了，，] 有大仙儿网友说：就类似于：select * from model where model.parentID=parentID 查询条件是parentID

千万别忘了。。。
