DevExpress GridControl 显示行号、设置行号宽

显示行号类

/// <summary>/// GridView 显示行号 设置行号列的宽度/// </summary>/// <param name="gv">GridView 控件名称</param>/// <param name="width">行号列的宽度 如果为null或为0 默认为30</param>public void DrawRowIndicator(DevExpress.XtraGrid.Views.Grid.GridView gv, int width) {gv.CustomDrawRowIndicator += new DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(gv_CustomDrawRowIndicator);if (width != null){if (width != 0){gv.IndicatorWidth = width;}else {gv.IndicatorWidth = 30;}}else {gv.IndicatorWidth = 30;}}//行号设置private void gv_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) {if (e.Info.IsRowIndicator && e.RowHandle > -1) {e.Info.DisplayText = (e.RowHandle + 1).ToString();}}

调用：

DrawRowIndicator(gridView1, 30);

备注：

显示行号可以直接给GridView添加CustomRowIndicator事件 ，，即上面的“行号设置”方法
