上一篇介绍了DataTable，这一篇在DT的基础之上再使用jquery的一款插件：treegrid,官网地址：http://maxazan.github.io/jquery-treegrid/
一、使用treegrid，需要以下支持
jquery.min.js+jquery.treegrid.min.js
二、后端提供树状列表格式的集合数据，借助前端的DT的配置控制，来在页面上输出满足treegrid格式要求的html
前台：
@using Model
@{
Layout = null;
UserInfo userInfo = null; if (ViewData["LoginUser"] != null)
{
userInfo = ViewData["LoginUser"] as UserInfo;
}
else
{
Response.Redirect("/Login/Index");
}

后台：

{

total = powerIq.Count();
List<Model.Power> powerList = powerIq.ToList();
powerList = TreeGridList(powerList);
dt.recordsTotal = total;
dt.recordsFiltered = total;
dt.data = powerList; return Json(dt);
} /// <summary>
/// 将List转换为TreeGrid格式的List
/// </summary>
private List<Model.Power> TreeGridList(List<Model.Power> powerList)
{
List<Model.Power> treegridList=new List<Model.Power>(); foreach (var powerOne in powerList.Where(a => a.ParentId == "" || a.PowerId.Length == ).OrderBy(a => a.Sort))//一级菜单
{
treegridList.Add(powerOne);
foreach (var powerTwo in powerList.Where(a => a.ParentId != "" && a.PowerId.Length == && a.ParentId == powerOne.PowerId).OrderBy(a=>a.Sort))//二级菜单
{
treegridList.Add(powerTwo);
foreach (var powerBtn in powerList.Where(a => a.ParentId != "" && a.PowerId.Length == && a.ParentId == powerTwo.PowerId).OrderBy(a => a.Sort))//按钮
{
treegridList.Add(powerBtn);
}
}
} return treegridList;
}
解释说明：
treegrid是通过tr标签上的class内容和tr的位置关系来组织表格中行之间的父子关系和位置关系的，
DT中的配置项：
"rowCallback": function (row, data, displayIndex) {//行定义
if (data.ParentId != "0") {
$(row).attr("class", "text-c treegrid-" + data.PowerId + " treegrid-parent-" + data.ParentId);
} else {
$(row).attr("class", "text-c treegrid-" + data.PowerId);
}
},
就是来控制父子关系的。
而后台的List顺序转换，是为了调整好输出的顺序，从而来控制tr之间的位置关系。
通过DT初始化好表格之后，调用
$("#table1").treegrid({
"initialState": 'collapsed',
});
即可，绘制好树状表格。
