GridControl如何显示行号

        //要设置一下.IndicatorWidth，要不然列会被遮挡

       this.gridView1.IndicatorWidth = 40;

      //显示行的序号

        privatevoid gridView1_CustomDrawRowIndicator(object sender,RowIndicatorCustomDrawEventArgs e)

        {

            if (e.Info.IsRowIndicator && e.RowHandle>=0)

            {

                e.Info.DisplayText = (e.RowHandle + 1).ToString();

            }

         }
