简单TreeList绑定数据

一、拖放控件

二、创建数据源绑定对象

/// <summary>
    /// 操作记录类型
    /// </summary>
    public class LogTypeInfo
    {
        /// <summary>
        /// ID
        /// </summary>
        public int Id { get; set; }
        /// <summary>
        /// 父节点ID
        /// </summary>
        public int ParentId { get; set; }
        /// <summary>
        /// 名称
        /// </summary>
        public string LogName { get; set; }
    }

三、绑定对象的值

/// <summary>
        /// 操作记录
        /// </summary>
        public static readonly List<string>  lstLogType = new List<string>() { 
            "所有日志","登录系统","退出系统","新增房源","修改房源","删除房源","激活房源",
            "资料房源","发布房源","打印房源","查看业主","资料业主","新增客源",
            };

以上都是准备工作。

开始作业，假设以“所有日志”作为父级，其它的作为子级

  

            //实例化数据源列表
            List<LogTypeInfo> lstTree = new List<LogTypeInfo>();
            //数据内容
            List<string> lstLogType = lstLogType;
            //给数据列表赋值
            for (int i = 0; i < lstLogType.Count; i++)
            {
                LogTypeInfo model = new LogTypeInfo();
                model.Id = i;
                model.LogName = lstLogType[i];
                //设置父子级别
                if (i > 0)
                {
                    model.ParentId = 0;
                }
                lstTree.Add(model);
            }
            //绑定父子级字段
            trLog.KeyFieldName = "Id";
            trLog.ParentFieldName = "ParentId";
            trLog.DataSource = lstTree;
            //展开节点
            trLog.ExpandAll();

结果如图

其中字体颜色可以通过CustomDrawNodeCell事件修改颜色

private void trLog_CustomDrawNodeCell(object sender, DevExpress.XtraTreeList.CustomDrawNodeCellEventArgs e)
        {
          
            if (trLog.DataSource != null)
            {
                switch (e.CellValue.ToString())
                {
                    case "登录系统":
                        e.Appearance.ForeColor = StaticHelper.gColorTextG;
                        break;
                    case "退出系统":
                        e.Appearance.ForeColor = StaticHelper.gColorTextC;
                        break;
                    case "新增房源":
                        e.Appearance.ForeColor = StaticHelper.gColorTextR;
                        break;
                    case "新增客源":
                        e.Appearance.ForeColor = StaticHelper.gColorTextR;
                        break;
                    case "自动转房客":
                        e.Appearance.ForeColor = StaticHelper.gColorTextR;
                        break;
                    case "合同记录":
                        e.Appearance.ForeColor = StaticHelper.gColorTextR;
                        break;
                    case "新增员工":
                        e.Appearance.ForeColor = StaticHelper.gColorTextR;
                        break;                   
                }
            }
        }
