DevExpress GridControl 显示行号、设置行号宽

显示行号类

  /// <summary>
        /// GridView  显示行号   设置行号列的宽度
        /// </summary>
        /// <param name="gv">GridView 控件名称</param>
        /// <param name="width">行号列的宽度 如果为null或为0 默认为30</param>
        public  void DrawRowIndicator(DevExpress.XtraGrid.Views.Grid.GridView gv, int width) {
            gv.CustomDrawRowIndicator += new DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(gv_CustomDrawRowIndicator);
            if (width != null)
            {
                if (width != 0)
                {
                    gv.IndicatorWidth = width;
                }
                else {
                    gv.IndicatorWidth = 30;
                }
            }
            else {
                gv.IndicatorWidth = 30;
            }

        }
        //行号设置
        private void gv_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) {
            if (e.Info.IsRowIndicator && e.RowHandle > -1) {
                e.Info.DisplayText = (e.RowHandle + 1).ToString();
            }
        }

调用：

 DrawRowIndicator(gridView1, 30);

备注：

显示行号可以直接给GridView添加CustomRowIndicator事件 ，即上面的“行号设置”方法
