Is there a print dialog for WPF that is combinated whit a print preview dialog in WPF like Google Chrome or Word does?
At this moment I use a the print preview dialog from Windows forms. I have also try for to use the WPF version of it. But WPF has no PrintPreviewDialog
or PrintPrewiewControl
. This is my code:
//To the top of my class file:
using Forms = System.Windows.Forms;
//in a methode on the same class:
PageSettings setting = new PageSettings();
setting.Landscape = true;
_document = new PrintDocument();
_document.PrintPage += _document_PrintPage;
_document.DefaultPageSettings = setting ;
Forms.PrintPreviewDialog printDlg = new Forms.PrintPreviewDialog();
printDlg.Document = _document;
printDlg.Height = 500;
printDlg.Width = 200;
try
{
if (printDlg.ShowDialog() == Forms.DialogResult.OK)
{
_document.Print();
}
}
catch (InvalidPrinterException)
{
MessageBox.Show("No printers found.", "Error", MessageBoxButton.OK, MessageBoxImage.Error);
}
I've also searched for a NuGet package but nothing found really good.
What you want to do, is to create an xpsDocument
out from the content you want to print (a flowDocument
) and use that XpsDocument
to preview the content, for example let say you have the following Xaml, with a flowDocument
that you want to print its content :
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<FlowDocumentScrollViewer>
<FlowDocument x:Name="FD">
<Paragraph>

WPF, which stands for
<Bold>Windows Presentation Foundation</Bold> ,
is Microsoft's latest approach to a GUI framework, used with the .NET framework.
Some advantages include:
</Paragraph>
<List>
<ListItem>
<Paragraph>
It's newer and thereby more in tune with current standards
</Paragraph>
</ListItem>
<ListItem>
<Paragraph>
Microsoft is using it for a lot of new applications, e.g. Visual Studio
</Paragraph>
</ListItem>
<ListItem>
<Paragraph>
It's more flexible, so you can do more things without having to write or buy new controls
</Paragraph>
</ListItem>
</List>
</FlowDocument>
</FlowDocumentScrollViewer>
<Button Content="Print" Grid.Row="1" Click="Button_Click"></Button>
</Grid>
the flowDocument Sample is from Wpf tutorials site
the print button Click event handler should looks like this :
private void Button_Click(object sender, RoutedEventArgs e)
{
if (File.Exists("printPreview.xps"))
{
File.Delete("printPreview.xps");
}
var xpsDocument = new XpsDocument("printPreview.xps", FileAccess.ReadWrite);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(xpsDocument);
writer.Write(((IDocumentPaginatorSource)FD).DocumentPaginator);
Document = xpsDocument.GetFixedDocumentSequence();
xpsDocument.Close();
var windows = new PrintWindow(Document);
windows.ShowDialog();
}
public FixedDocumentSequence Document { get; set; }
so here you are mainly :
FlowDocument
content into that file,XpsDocument
to the PrintWindow
in which you will
handle the preview and the print actions,here how the PrintWindow
looks like :
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="1.5*"/>
</Grid.ColumnDefinitions>
<StackPanel>
<Button Content="Print" Click="Button_Click"></Button>
<!--Other print operations-->
</StackPanel>
<DocumentViewer Grid.Column="1" x:Name="PreviewD">
</DocumentViewer>
</Grid>
and the code behind :
public partial class PrintWindow : Window
{
private FixedDocumentSequence _document;
public PrintWindow(FixedDocumentSequence document)
{
_document = document;
InitializeComponent();
PreviewD.Document =document;
}
private void Button_Click(object sender, RoutedEventArgs e)
{
//print directly from the Xps file
}
}
the final result looks something like this
Ps: to use XpsDocument you should add a reference to System.Windows.Xps.Packaging namespace
