为Wpf DocumentViewer PrintDialog设置PageOrientation
提问于 2009-06-16 19:48:55
使用Wpf DocumentViewer控件时，我不知道如何在用户单击print按钮时DocumentViewer显示的PrintDialog上设置PageOrientation。有没有办法连接到这里面？

Mike's answer起作用了。我选择实现它的方式是创建我自己的文档查看器，该查看器派生自DocumentViewer。此外，将Document属性强制转换为FixedDocument对我来说不起作用，而强制转换为FixedDocumentSequence对我来说是无效的。
GetDesiredPageOrientation是你所需要的任何东西。在我的例子中，我检查了第一页的尺寸，因为我生成的文档对于文档中的所有页面都是统一的大小和方向，并且序列中只有一个文档。
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Controls;
using System.Windows.Xps;
using System.Printing;
using System.Windows.Documents;
public class MyDocumentViewer : DocumentViewer
{
protected override void OnPrintCommand()
{
// get a print dialog, defaulted to default printer and default printer's preferences.
PrintDialog printDialog = new PrintDialog();
printDialog.PrintQueue = LocalPrintServer.GetDefaultPrintQueue();
printDialog.PrintTicket = printDialog.PrintQueue.DefaultPrintTicket;
// get a reference to the FixedDocumentSequence for the viewer.
FixedDocumentSequence docSeq = this.Document as FixedDocumentSequence;
// set the default page orientation based on the desired output.
printDialog.PrintTicket.PageOrientation = GetDesiredPageOrientation(docSeq);
if (printDialog.ShowDialog() == true)
{
// set the print ticket for the document sequence and write it to the printer.
docSeq.PrintTicket = printDialog.PrintTicket;
XpsDocumentWriter writer = PrintQueue.CreateXpsDocumentWriter(printDialog.PrintQueue);
writer.WriteAsync(docSeq, printDialog.PrintTicket);
}
}

我用来在DocumentViewer的print对话框上设置方向的变通方法是隐藏DocumentViewer控件上的print按钮，方法是在模板中省略该按钮。然后，我提供了自己的打印按钮，并将其绑定到以下代码：
public bool Print()
{
PrintDialog dialog = new PrintDialog();
dialog.PrintQueue = LocalPrintServer.GetDefaultPrintQueue();
dialog.PrintTicket = dialog.PrintQueue.DefaultPrintTicket;
dialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
if (dialog.ShowDialog() == true)
{
XpsDocumentWriter writer = PrintQueue.CreateXpsDocumentWriter(dialog.PrintQueue);
writer.WriteAsync(_DocumentViewer.Document as FixedDocument, dialog.PrintTicket);
return true;
}
return false;
