DevExpress的GridControl如何实现打印和打印预览

第一种方法：

            System.Drawing.Printing.PageSettings set_print_page  =   new  System.Drawing.Printing.PageSettings();            DevExpress.XtraPrinting.DynamicPrintHelper ph  =   new  DevExpress.XtraPrinting.DynamicPrintHelper();             if  (ph.IsPrintingAvailable)            {                ph.PageSettings  =  set_print_page;                ph.PageSettings.Landscape  =   true ;                 ph.ShowPreview( this .gc,  true );            }

 

第二种方法：

 

            if  (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)            {                DataRowView drv  =  (DataRowView)BS_Roads.Current;                PrintingSystem ps  =   new  PrintingSystem();                PrintableComponentLink link  =   new  PrintableComponentLink(ps);                link.Component  =  gc;                link.Landscape  =   true ;                PageHeaderFooter phf  =  link.PageHeaderFooter  as  PageHeaderFooter;                phf.Header.Content.Clear();                phf.Header.Content.AddRange( new   string [] {  "" , drv[ " 线路名 " ].ToString()  +   " 站点信息表 " ,  ""  });                phf.Header.Font  =   new  System.Drawing.Font( " 宋体 " ,  16 , System.Drawing.FontStyle.Regular);                phf.Header.LineAlignment  =  BrickAlignment.Center;                phf.Footer.Content.Clear();                phf.Footer.Content.AddRange( new   string [] {  "" , String.Format( " 打印时间: {0:g} " , DateTime.Now),  ""  });                link.CreateDocument();                link.ShowPreview();            }             else             {                XtraMessageBox.Show( " 打印机不可用... " ,  " 提示 " , MessageBoxButtons.OK, MessageBoxIcon.Information);            }
