使用 DocumentViewer 控件时如何设置打印作业的名称？

发布于 2024-07-14 17:20:05 字数 343 浏览 15 评论 0原文

我使用 WPF DocumentViewer 控件来显示 XPS 文档，如下所示：

viewer.Document = xpsDocument.GetFixedDocumentSequence();

单击文档查看器内的打印按钮时，所有内容都可以正常打印，但是打印作业的名称是 System.Windows.Documents.FixedDocumentSequence，它小于理想的。

如何设置打印作业的名称？

我知道使用 PrintDialog.PrintDocument() 可以让我设置名称，但我不知道如何使用 DocumentViewer 控件来设置名称。

I've using the WPF DocumentViewer control to display an XPS Document like so:

viewer.Document = xpsDocument.GetFixedDocumentSequence();

When the print button inside the document viewer is clicked everything prints okay, however the name of the print job is System.Windows.Documents.FixedDocumentSequence, which is less than ideal.

How do I set the name of the print job?

I know using PrintDialog.PrintDocument() lets me set the name, but I can't see how to do it using the DocumentViewer control.

我找到了解决方案。

将其添加到 XAML

<Window.CommandBindings>
    <CommandBinding Command="ApplicationCommands.Print" PreviewExecuted="CommandBinding_PreviewExecuted" Executed="CommandBinding_Executed" />
</Window.CommandBindings>

并将其添加到背后的代码中

private void CommandBinding_PreviewExecuted(object sender, ExecutedRoutedEventArgs e)
{
    PrintDialog dialog = new PrintDialog();
    if (dialog.ShowDialog() == true)
    {
        dialog.PrintDocument(Document.DocumentPaginator, "Print Job Title");
    }
}

private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
    //needed so that preview executed works
}

有几件事值得注意。如果未绑定 Exectued 事件，则 PreviewExecuted 方法不会发生。不知道为什么。

I found a solution.

Add this to the XAML

<Window.CommandBindings>
    <CommandBinding Command="ApplicationCommands.Print" PreviewExecuted="CommandBinding_PreviewExecuted" Executed="CommandBinding_Executed" />
</Window.CommandBindings>

And this to the code behind

private void CommandBinding_PreviewExecuted(object sender, ExecutedRoutedEventArgs e)
{
    PrintDialog dialog = new PrintDialog();
    if (dialog.ShowDialog() == true)
    {
        dialog.PrintDocument(Document.DocumentPaginator, "Print Job Title");
    }
}

private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
{
    //needed so that preview executed works
}

A couple of things of note. The PreviewExecuted method doesn't happen if the Exectued event isn't bound to. Don't know why.

我遇到了同样的问题，但是覆盖打印命令在我的情况下不起作用，所以我找到了另一种同样有效的解决方法

internal class MyDocumentViewer : DocumentViewer
{
    public string JobTitle { get; set; }

    protected override void OnPrintCommand()
    {
        PrintDialog dialog = new PrintDialog();
        if (dialog.ShowDialog() == true)
            dialog.PrintDocument(Document.DocumentPaginator, JobTitle);
    }
}

I had the same issue however overriding the Print command wouldn't work in my situation so i found another work around that works equally well

internal class MyDocumentViewer : DocumentViewer
{
    public string JobTitle { get; set; }

    protected override void OnPrintCommand()
    {
        PrintDialog dialog = new PrintDialog();
        if (dialog.ShowDialog() == true)
            dialog.PrintDocument(Document.DocumentPaginator, JobTitle);
    }
}
