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

 1 public static void SetRowNumberIndicator(GridView gridView)

 2         {

 3             gridView.BeginUpdate();

 4             gridView.OptionsView.ShowIndicator = true;

 5             gridView.CustomDrawRowIndicator += new RowIndicatorCustomDrawEventHandler(

 6                 delegate(object sender, RowIndicatorCustomDrawEventArgs e)

 7                 {

 8                     if (e.RowHandle >= 0)

 9                     {

10                         int rowNumber = e.RowHandle + 1;

11                         e.Info.DisplayText = rowNumber.ToString();

12                     }

13                 }

14             );

15

16             gridView.DataSourceChanged += new EventHandler(

17                 delegate(object sender, EventArgs e)

18                 {

19                     gridView.IndicatorWidth = 22 + gridView.DataRowCount.ToString().Length * ((int)gridView.Appearance.HeaderPanel.Font.Size);

20                 }

21             );

22

23             gridView.EndUpdate();

24         }

效果如下
