1. 界面顯示

2.前端 jqgrid 代码   

 //加载表格
    function GetGrid() {
        var selectedRowIndex = 0;
        var $gridTable = $('#gridTable');
        $gridTable.jqGrid({
            url: "../../BaseManager/Organize/GetTreeListJson",
            datatype: "json",
            height: $(window).height() - 108.5,
            colModel: [
                { label: '主键', name: 'OrganizeId', hidden: true },
                { label: "公司名称", name: "FullName", width: 300, align: "left", sortable: false },
                { label: "外文名称", name: "EnCode", width: 150, align: "left", sortable: false },
                { label: "中文名称", name: "ShortName", width: 150, align: "left", sortable: false },
                { label: "公司性质", name: "Nature", width: 100, align: "left", sortable: false },
                {
                    label: "成立时间", name: "FoundedTime", width: 100, align: "left", sortable: false,
                    formatter: function (cellvalue, options, rowObject) {
                        return formatDate(cellvalue, 'yyyy-MM-dd');
                    }
                },
                { label: "负责人", name: "Manager", width: 100, align: "left", sortable: false },
                { label: "经营范围", name: "Businessscope", width: 200, align: "left", sortable: false },
                { label: "备注", name: "Description", width: 200, align: "left", sortable: false }
            ],
            treeGrid: true,
            treeGridModel: "nested",
            ExpandColumn: "EnCode",
            rowNum: "all",
            rownumbers: true,
            onSelectRow: function () {
                selectedRowIndex = $("#" + this.id).getGridParam('selrow');
            },
            gridComplete: function () {
                $("#" + this.id).setSelection(selectedRowIndex, false);
            }
        });

3.后端controllers  

/// <summary>
        /// 机构列表 
        /// </summary>
        /// <param name="condition">查询条件</param>
        /// <param name="keyword">关键字</param>
        /// <returns>返回树形列表Json</returns>
        [HttpGet]
        public ActionResult GetTreeListJson(string condition, string keyword)
        {
            var data = NewObject<OrganizeLogic>().GetListByCache().datas;
            if (!string.IsNullOrEmpty(condition) && !string.IsNullOrEmpty(keyword))
            {
                #region 多条件查询
                switch (condition)
                {
                    case "FullName":    //公司名称
                        data = data.TreeWhere(t => t.FullName.Contains(keyword), "OrganizeId");
                        break;
                    case "EnCode":      //外文名称
                        data = data.TreeWhere(t => t.EnCode.Contains(keyword), "OrganizeId");
                        break;
                    case "ShortName":   //中文名称
                        data = data.TreeWhere(t => t.ShortName.Contains(keyword), "OrganizeId");
                        break;
                    case "Manager":     //负责人
                        data = data.TreeWhere(t => t.Manager.Contains(keyword), "OrganizeId");
                        break;
                    default:
                        break;
                }
                #endregion
            }
            var treeList = new List<TreeGridEntity>();
            foreach (OrganizeEntity item in data)
            {
                TreeGridEntity tree = new TreeGridEntity();
                bool hasChildren = data.Count(t => t.ParentId == item.OrganizeId) == 0 ? false : true;
                tree.id = item.OrganizeId.ToConvertString();
                tree.hasChildren = hasChildren;
                tree.parentId = item.ParentId.ToString();
                tree.expanded = false;
                tree.entityJson = JsonHelper.ToJson(item);
                treeList.Add(tr
