DevExpress GridControl 显示行号

 

//在GridView的CustomDrawRowIndicator事件中添加如下代码：

 private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
  {
            if (e.Info.IsRowIndicator && e.RowHandle >= 0)
            {
                e.Info.DisplayText = e.RowHandle.ToString();
            }
}
//要调整行号列的宽度只需要调整gridview1.IndicatorWidth属性即可
