这篇文章主要介绍了DevExpress实现GridView当无数据行时提示消息,需要的朋友可以参考下
本文实例展示了DevExpress实现GridView当无数据行时提示消息的方法，具体步骤如下：
主要功能代码部分如下：

1. /// <summary> /// 设置当没有数据行的提示信息『CustomDrawEmptyForeground』 /// </summary> /// <param name="gridView">GridView</param> /// <param name="e">CustomDrawEventArgs</param> /// <param name="noRecordMsg">提示信息</param> public static void DrawNoRowCountMessage(this GridView gridView, CustomDrawEventArgs e, string noRecordMsg) { if (gridView == null) throw new ArgumentNullException("gridView"); if (gridView.RowCount == 0) { if (!string.IsNullOrEmpty(noRecordMsg)) { Font _font = new Font("宋体", 10, FontStyle.Bold); Rectangle _r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5); e.Graphics.DrawString(noRecordMsg, _font, Brushes.Black, _r); } } }

复制代码

private void gvLampTotal_CustomDrawEmptyForeground(object sender, DevExpress.XtraGrid.Views.Base.CustomDrawEventArgs e)
{
gvLampTotal.DrawNoRowCountMessage(e, "暂无符合的数据！");
}
代码运行效果如下：
