Question

我想在双面打印gridview我尝试了下面显示的代码。但这一行显示错误XtraReport1 r = new XtraReport1();。如何在打印gridView时使其工作？ 我得到

  

CS0246：找不到类型或命名空间名称“XtraReport1”。   您是否缺少using指令或程序集引用？

    private void btnPrintPreview_Click(object sender, EventArgs e)
       {
            XtraReport1 r = new XtraReport1();
            r.PrintingSystem.StartPrint += new DevExpress.XtraPrinting.PrintDocumentEventHandler(PrintingSystem_StartPrint);
            r.ShowPreview();
        }

        private void PrintingSystem_StartPrint(object sender, DevExpress.XtraPrinting.PrintDocumentEventArgs e) {
            e.PrintDocument.PrinterSettings.Duplex = System.Drawing.Printing.Duplex.Horizontal;
        }

Get/Set PageSettings and PrinterSettings to XtraReports reconized by preview and print

1. 要打印网格控件，您应该使用 GridControl.Print或GridControl.ShowPrintPreview方法。
2. 然后处理BaseView.PrintInitialize事件以自定义打印设置。

请参阅此示例，该示例可让您了解如何进行打印事件以进一步自定义：

public Form1()
{
    InitializeComponent();
    sqlDataSource1.Fill();

}

private void button1_Click(object sender, EventArgs e)
{
    gridControl1.Print();
}

private void gridView1_PrintInitialize(object sender, DevExpress.XtraGrid.Views.Base.PrintInitializeEventArgs e)
{
    PrintingSystemBase pb = e.PrintingSystem as PrintingSystemBase;
    pb.StartPrint -= pb_StartPrint;
    pb.StartPrint +=pb_StartPrint;


}

void pb_StartPrint(object sender, PrintDocumentEventArgs e)
{
    e.PrintDocument.PrinterSettings.Duplex = System.Drawing.Printing.Duplex.Horizontal;
    //e.PrintDocument.PrinterSettings.PrintToFile = true;
    e.PrintDocument.PrinterSettings.PrinterName = "Foxit Reader PDF Printer";

}
