Dev的GridView中如何自动生成行号

这里提供一个方法，使用简单，只需将GridView传入，即可自动生成行号

 public static void SetRowNumberIndicator(GridView gridView)
         {
             gridView.BeginUpdate();
             gridView.OptionsView.ShowIndicator = true;
             gridView.CustomDrawRowIndicator += new RowIndicatorCustomDrawEventHandler(
                 delegate(object sender, RowIndicatorCustomDrawEventArgs e)
                 {
                     if (e.RowHandle >= )
                     {
                         int rowNumber = e.RowHandle + ;
                         e.Info.DisplayText = rowNumber.ToString();
                     }
                 }
             );

             gridView.DataSourceChanged += new EventHandler(
                 delegate(object sender, EventArgs e)
                 {
                     gridView.IndicatorWidth =  + gridView.DataRowCount.ToString().Length * ((int)gridView.Appearance.HeaderPanel.Font.Size);
                 }
             );

             gridView.EndUpdate();
         }

效果如下
