放在主程序 入口处，

public Form1()        {            InitializeComponent();            gridView1.IndicatorWidth = 50; //
        <宽度值>
         官方推荐常用是30，至于多少自己根据自己的需求和喜好去修改宽度的大小。        }
        

则每次程序运行时都能正确完整的显示序列号。

 

 

附送2种方法。

private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)        {            e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;            if (e.Info.IsRowIndicator)            {                if (e.RowHandle >= 0)                {                    e.Info.DisplayText = (e.RowHandle + 1).ToString();                }                else if (e.RowHandle < 0 && e.RowHandle > -1000)                {                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;                    e.Info.DisplayText = "G" + e.RowHandle.ToString();                }            }            gridView1.IndicatorWidth = 60;            #region MyRegion            //if (e.Info.IsRowIndicator)            //{            //    e.Info.DisplayText = e.RowHandle.ToString();            //}            //gridView1.IndicatorWidth = 30;             #endregion        }
