DevExpress的GridControl如何实现打印和打印预览 z

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);

            }
