Capture Print Event

[Benedikt]

Hi guys,

 

I'm trying to capture the print event of a RadPDFViewer to not only print the PDF but also save it to a predifined location everytime it is printed.

Ithought about the Click event in the toolbar, but I also need to capture it if printed from contextmenu.

 

I have read something about inherit the print command, but I haven't gotten how to do that.

 

Greetings,

Benedikt

Hi Benedikt,

Yes creating a custom command is suitable for this case. Here is an example that shows how you can implement that: 

public partial class MainWindow : Window
{      
    public MainWindow()
    {
        InitializeComponent();
        this.pdfViewer.CommandDescriptors = new CustomCommandDescriptors(this.pdfViewer);
    }
}
public class MyPrintPdfDocumentCommand : PrintPdfDocumentCommand
{
    public MyPrintPdfDocumentCommand(FixedDocumentViewerBase fixedDocumentViewerBase) : base(fixedDocumentViewerBase)
    {
    }
    public override void Execute(object parameter)
    {
        //save or perform other action
        base.Execute(parameter);
    }
}
public class CustomCommandDescriptors : DefaultCommandDescriptors
{
    private readonly CommandDescriptor printCommandDescriptor;

    public new CommandDescriptor PrintCommandDescriptor
    {
        get
        {
            return this.printCommandDescriptor;
        }
    }

    public CustomCommandDescriptors(FixedDocumentViewerBase fixedDocumentViewerBase)   : base(fixedDocumentViewerBase)
    {
        this.printCommandDescriptor = new CommandDescriptor(new MyPrintPdfDocumentCommand(fixedDocumentViewerBase));
    }
}

I hope this helps. Should you have any other questions do not hesitate to ask.
