DevExpress实现GridView当无数据行时提示消息_C#教程

分享到:

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:

/// <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);
 }
  }
}

代码使用方法如下:

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:
