如何在C＃中打印gridview雙面打印 - devexpress

Question

我想在雙面打印中打印gridview，我嘗試了下面顯示的代碼。但是這行顯示錯誤XtraReport1 r = new XtraReport1();。如何在打印gridView時使其工作？ 我得到

CS0246：類型或命名空間名稱'XtraReport1' 找不到。 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; 
     }

去通過文檔：

How to: Customize Print Settings When Printing GridControl
Preset PrinterSettings
Get/Set PageSettings and PrinterSettings to XtraReports reconized by preview and print

1. 至Pr在網格控件中，您應該使用 GridControl.Print或GridControl.ShowPrintPreview方法。
2. 然後處理BaseView.PrintInitialize事件以自定義打印設置。

看到這個例子讓你知道如何進行進一步的自定義訪問打印事件：

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";
