PDFsharp - How to create a 2nd page

Question

I can\'t find documentation in PDFsharp to show how to add a 2nd page using C#!

As an example, over in VB6 I use a PDF creation method called mjwPDF. To indicate th

Answer 1

you can print in multiple pages by decreasing the size of "Ypoint" as shown below code.

its given value is "yPoint = yPoint + 40"

change it to "yPoint = yPoint + 8" i.e increment ypoint by +8 in every loop iteration,

reply for any doubts. refer while loop below

        While dr.Read

            username = dr.Item(0)
            Action_Performed = dr.Item(1)
            datetim = dr.Item(2)

            graph.DrawString(username, font, XBrushes.Black, _
               New XRect(40, yPoint, pdfPage.Width.Point, pdfPage.Height.Point), XStringFormats.TopLeft)

            graph.DrawString(Action_Performed, font, XBrushes.Black, _
              New XRect(280, yPoint, pdfPage.Width.Point, pdfPage.Height.Point), XStringFormats.TopLeft)

            graph.DrawString(datetim, font, XBrushes.Black, _
               New XRect(420, yPoint, pdfPage.Width.Point, pdfPage.Height.Point), XStringFormats.TopLeft)
            yPoint = yPoint + 10
            counter += 1
            If counter = 30 Then
                pdfPage = pdf.AddPage()
                graph.Dispose()
                graph = XGraphics.FromPdfPage(pdfPage)
                font = New XFont("Verdana", 7, XFontStyle.Regular)
                yPoint = 0
                yPoint = yPoint + 100
                counter = 0
            End If
        End While
        Dim pdfFilename As String = "dbtopdf.pdf"
        pdf.Save(pdfFilename)
        Process.Start(pdfFilename)

Answer 2

Do not forget to update your "canvas" or "graphics" object variable to the new page:

You may be doing something like this:

// First time:
this.page = document.AddPage();
this.gfx = XGraphics.FromPdfPage(page);

...

// next time (forgot to update graphics or canvas variable):
this.page = document.AddPage();

And, it should be something like:

// First time:
this.page = document.AddPage();
this.gfx = XGraphics.FromPdfPage(page);

...

// next time:
this.page = document.AddPage();
// update graphics object, also
this.gfx = XGraphics.FromPdfPage(page);

I also made that mistake.

Answer 3

Before trying to create a new XGraphics object for the new page, dispose the old existing object:

xgrObject.Dispose();

Answer 4

You create a new page with

document.AddPage();

and then call

XGraphics.FromPdfPage(page);

to get a gfx object for the second page (probably this is the missing step).

So repeat those steps from your code sample for every new page:

// Create an empty page
PdfPage page = document.AddPage();

// Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);

Update: In your loop you do the following:

document.AddPage();
XGraphics.FromPdfPage(page);

AddPage() returns a "handle" to the newly created page - which you throw in the bin. Then you call "XGraphics.FromPdfPage()" to create yet another gfx for the first page - which you also would throw in the bin, but you get an exception since there already is a gfx for the first page.

A small change should do the trick:

page = document.AddPage();
gfx = XGraphics.FromPdfPage(page);

"I never dreamed adding a second page could be so difficult! No luck with the suggested code."
PDFsharp includes quite a few working samples to get people going. No luck with the suggested code since you ignored the important part - the values returned by the methods.
