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);

}
