PDFsharp & MigraDoc Foundation

I'm am under the assumption that if I do the following:

and SetStyle contains the initialization of style as found elsewhere in this forum, that a new paragraph created with .AddParagraph is of the style StyleNames.Normal.

However, when I do a .renderobject with this paragraph I get the error: Value of '0' is not valid for 'emSize'. 'emSize' should be greater than 0 and less than or equal to System.Single.MaxValue

Even when I set style active for the paragraph with para.Style = StyleNames.Normal it doesn´t work.

However when I do: para.Format.Font.Size = MigraDoc.DocumentObjectModel.Unit.FromPoint(iFontSize) the .renderobject succeeds.

How come the style is not being applied?

I ran into something similar. When I did create a new document, I needed to re-associate my XGraphics object with my new MigraDoc document/page because the XGraphics encapsulates the use of a document/page.

My C# example is as follows:

*******************************
//We need to make a new page here.
myPDFPage = AddPDFPage(pdfdocument);

//Reinitialize XGraphics
gfx = XGraphics.FromPdfPage(myPDFPage);
font = new XFont("Arial", 11, XFontStyle.Regular);
gfx.DrawString(" ", font, XBrushes.Black,
new XRect(0, 0, myPDFPage.Width, myPDFPage.Height), XStringFormats.Center);

gfx.MUH = PdfFontEncoding.Unicode;
gfx.MFEH = PdfFontEmbedding.Default;

// You always need a MigraDoc document for rendering.
myMigraDocPage = myMigradocDoc.AddSection();

//...Later I perform the following bound with the new doc/page created above.
myMigradocDoc = myMigraDocPage.Document;
docRenderer = new DocumentRenderer(myMigradocDoc);
docRenderer.PrepareDocument();

docRenderer.RenderObject(gfx,...)
*******************************

Hope this thought helps.

With neither sample code nor MDDDL file there is nothing I can do.

In this post are the MDDDL file for the report and a ASP.net VB file that creates the report.

If I comment out the lines that define the paragraph (around line 131), I get em-size error, although the paragraph has a defined style.

Not strange, just upload a ZIP file.

I would think that such a forum-close format would be allowed thats why.
I enclosed the needed files in my previous post.

Using a ZIP file ensures that the file I download is the file you uploaded.
There are so many character sets that I don't trust text files (including XML or HTML) to be handled correctly. We've seen wonderful changes occur when sending XML or HTML as an e-mail attachment. ZIP files normally don't get tampered - and they have a CRC check that detects modifications.

Back to topic: I can create a document from your MDDDL file without error.

I'm sorry but I don't have the time to build a project around your ASPX file so I haven't tried that yet.

By the way:
