本文實例展示了DevExpress實現GridView當無數據行時提示消息的方法,具體步驟如下:
主要功能代碼部分如下:
/// <summary>/// 設置當沒有數據行的提示信息『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("宋體", 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); } }}
代碼使用方法如下:
private void gvLampTotal_CustomDrawEmptyForeground(object sender, DevExpress.XtraGrid.Views.Base.CustomDrawEventArgs e){ gvLampTotal.DrawNoRowCountMessage(e, "暫無符合的數據!");}
代碼運行效果如下:
