尝试了很多方法，终于找到了GridControl中GridView表格行拖拽的方式，从这个链接（）中获得的灵感，但还存在问题，

比如用gridView1.Columns[“排序列名”].SortOrder = DevExpress.Data.ColumnSortOrder.Ascending;实现的排序，

只是在界面显示上实现了排序，但绑定的数据表格行并没有变动！

所以我直接对绑定的表格操作，实现行的排序。

示例图如下（不知道怎么做动图）：

实现代码如下：

const string OrderFieldName = "序号";        GridHitInfo downHitInfo = null;        DataTable dt = new DataTable();        public Form1()        {            InitializeComponent();        }        /// 
        /// 窗体加载        /// 
        ///         ///         private void Form1_Load(object sender, EventArgs e)        {            //填充数据            dt.Columns.Add(OrderFieldName);            dt.Columns.Add("列2");            dt.Columns.Add("列3");            dt.Rows.Add("1", "第一行数据", "1");            dt.Rows.Add("2", "第二行数据", "2");            dt.Rows.Add("3", "第三行数据", "3");            dt.Rows.Add("4", "第四行数据", "4");            dt.Rows.Add("5", "第五行数据", "5");            dt.Rows.Add("6", "第六行数据", "6");            gridControl1.DataSource = dt;            gridView1.OptionsCustomization.AllowSort = false;            gridView1.OptionsView.ShowGroupPanel = false;            gridControl1.AllowDrop = true;            gridView1.OptionsBehavior.Editable = false;        }        /// 
        /// 上移行        /// 
        ///         ///         private void btn_up_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)        {            gridControl1.Focus();            int index = gridView1.FocusedRowHandle;            if (index <= 0) return;            ChangeRow(index, index - 1);        }        ///
