 |
|
Hi everybody,
I am a new PDFSharp french user and in fact I've encountered a worry.
I bind one MigraDoc paragraph with MS SQL data source and I dont know how to auto adding pages when you've out of space.
I give you my code, please help me
| Code: | protected void LinkButtonPDF_Click(object sender, EventArgs e)
{
DateTime time;
// Create new PDF document
PdfDocument document = new PdfDocument();
time = document.Info.CreationDate;
document.Info.Title = "Fiche produit FISA";
document.Info.Author = "FAUCONNET Ingénierie SA";
document.Info.Subject = "Server time: " +
time.ToString("F", CultureInfo.InvariantCulture);
// Create new page
PdfPage page = document.AddPage();
page.Width = XUnit.FromMillimeter(210);
//page.Height = XUnit.FromMillimeter(297);
// Create graphics object and draw clock
XGraphics gfx = XGraphics.FromPdfPage(page);
//XGraphics formGfx = XGraphics.FromForm(page);
// Create a font
XFont font = new XFont("Verdana", 12, XFontStyle.Regular);
XFont font2 = new XFont("Trebuchet MS", 25, XFontStyle.Bold);
XFont font3 = new XFont("Trebuchet MS", 17, XFontStyle.Bold);
XFont fontTitre = new XFont("Trebuchet MS", 15, XFontStyle.Underline);
String path = "D:/HostingSpaces/jerome@fisa.fr/fisa.fr.sphere-hosting.com/wwwroot/images/bg_top.png";
XImage img = XImage.FromFile(path);
gfx.DrawImage(img, 0, 0, page.Width, 112);
String path2 = "D:/HostingSpaces/jerome@fisa.fr/fisa.fr.sphere-hosting.com/wwwroot/images/logo00.png";
XImage logo = XImage.FromFile(path2);
gfx.DrawImage(logo, 10, 15);
gfx.DrawString("Services et support technique", font2, XBrushes.DarkSlateGray, new XRect(0, 35, page.Width, page.Height), XStringFormat.TopCenter);
gfx.DrawString("Logiciel Fauconnet Ingénirie SA", font3, XBrushes.DarkGray, new XRect(0, 57, page.Width, page.Height), XStringFormat.TopCenter);
String StrConnect = ConfigurationManager.ConnectionStrings["supportConnectionString"].ConnectionString;
SqlConnection Connection = new SqlConnection(StrConnect);
Connection.Open();
SqlCommand command = new SqlCommand("SELECT titre_fr, commentaire_fr, date_publication FROM articles INNER JOIN titre_traduction ON titre_traduction.id_titre=articles.id_titre_ INNER JOIN commentaire_traduction ON commentaire_traduction.id_commentaire=articles.id_commentaire_ WHERE type_fiche=1 AND id_produits_=@id_art", Connection);
command.Parameters.Add("@id_art", SqlDbType.Int, 10);
command.Parameters["@id_art"].Value = Request.QueryString["produit_id"];
//on créé le reader pour parcourir le résultat de la requête précédente
SqlDataReader read = command.ExecuteReader();
int y = 120;
int y2 = 150;
while (read.Read())
{
string titre = (string)read["titre_fr"];
string comment = (string)read["commentaire_fr"];
DateTime date_pub = (DateTime)read["date_publication"];
string result1 = String.Format(titre);
string result2 = String.Format("Mise en ligne le : "+date_pub);
string result3 = String.Format(comment);
gfx.DrawString(result1, fontTitre, XBrushes.DarkSlateGray, new XRect(20, y, page.Width, page.Height), XStringFormat.TopLeft);
gfx.DrawString(result2, font, XBrushes.Black, new XRect(20, 140, page.Width, page.Height), XStringFormat.TopLeft);
y += 40;
y2 += 40;
// You always need a MigraDoc document for rendering.
Document doc = new Document();
Section sec = doc.AddSection();
// Add a single paragraph with some text and format information.
Paragraph para = sec.AddParagraph();
para.Format.Alignment = ParagraphAlignment.Left;
para.Format.Font.Name = "Trebuchet MS";
para.Format.Font.Size = 10;
para.Format.Font.Color = MigraDoc.DocumentObjectModel.Colors.SlateGray;
para.AddText(comment);
para.Format.Borders.Distance = "2pt";
para.Format.Borders.Color = Colors.DarkGray;
// Create a renderer and prepare (=layout) the document
MigraDoc.Rendering.DocumentRenderer docRenderer = new DocumentRenderer(doc);
docRenderer.PrepareDocument();
// Render the paragraph. You can render tables or shapes the same way.
docRenderer.RenderObject(gfx, XUnit.FromCentimeter(1), XUnit.FromCentimeter(6), "19cm", para);
}
// Fermeture connection
Connection.Close();
// Draw the text
gfx.DrawString("Généré le : " + time.ToString(), font, XBrushes.Black, new XRect(0, 0, page.Width, page.Height), XStringFormat.BottomCenter);
//RenderClock(gfx);
// Send PDF to browser
MemoryStream stream = new MemoryStream();
document.Save(stream, false);
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", stream.Length.ToString());
Response.BinaryWrite(stream.ToArray());
Response.Flush();
stream.Close();
Response.End();

MigraDoc adds pages automatically (if used correctly).
After calling "docRenderer.PrepareDocument()" MigraDoc should know how many pages are needed.

Thank you for your reply,
I have tried to specify the number of pages as you advised me previously.
This time I have well 2 pages but in only one page.
I am so confusing, I don't arrive to find the right solution.
Please help me again, I have the feeling that I am near.
I give you my code
| Code: | PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(true);
pdfRenderer.Document = doc;
pdfRenderer.RenderDocument();
pdfRenderer.PrepareRenderPages();
pdfRenderer.RenderPages(1,2);
// Create a renderer and prepare (=layout) the document
DocumentRenderer docRenderer = new DocumentRenderer(doc);
docRenderer.PrepareDocument();
docRenderer.RenderPage(gfx, 1, PageRenderOptions.All);
docRenderer.RenderPage(gfx, 2, PageRenderOptions.All);
//docRenderer.RenderObject(gfx, XUnit.FromCentimeter(1), XUnit.FromCentimeter(6), "19cm",para);
// Draw the text
gfx.DrawString("Généré le : " + time.ToString(), font, XBrushes.Black, new XRect(0, 0, page.Width, page.Height), XStringFormat.BottomCenter);
// Send PDF to browser
MemoryStream stream = new MemoryStream();
document.Save(stream, false);
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", stream.Length.ToString());
Response.BinaryWrite(stream.ToArray());
Response.Flush();
stream.Close();
Response.End(); |
Thank you in advance

You're code requires you to create the pages.
So before calling
| Code: | | docRenderer.RenderPage(gfx, 2, PageRenderOptions.All); |
to render the second page, make sure you created a second page and set gfx to that page.
The way you use it, it gives you all opportunities to modify the created pages - this includes rendering two document pages on one PDF page.
Or look at the MigraDoc samples to let MigraDoc do the work.

Thank you very much Thomas Hoevel for your patience.
I arrive now to render my content in 2 pages by making it:
| Code: | // Create a renderer and prepare (=layout) the document
DocumentRenderer docRenderer = new DocumentRenderer(doc);
docRenderer.PrepareDocument();
docRenderer.RenderPage(gfx, 1, PageRenderOptions.RenderContent);
PdfPage page2 = document.AddPage();
page2.Size = PdfSharp.PageSize.A4;
gfx = XGraphics.FromPdfPage(page2);
docRenderer.RenderPage(gfx, 2, PageRenderOptions.RenderContent);
|
The only problem is that my content takes place on my image in the top of my first page.
I would like to know if it's possible to do the same thing by making it:
| Code: | // Create a renderer and prepare (=layout) the document
DocumentRenderer docRenderer = new DocumentRenderer(doc);
docRenderer.PrepareDocument();
docRenderer.RenderObject(gfx, XUnit.FromCentimeter(1), XUnit.FromCentimeter(6), "19cm",para);
PdfPage page2 = document.AddPage();
page2.Size = PdfSharp.PageSize.A4;
gfx = XGraphics.FromPdfPage(page2);
docRenderer.RenderObject(gfx, XUnit.FromCentimeter(1), XUnit.FromCentimeter(1), "19cm", para); |
In fact, I would like to know if it's possible to specify the page number by calling | Code: | | docRenderer.RenderObject() |
In this way, I can re-size and give a position to my contents.
Thank you again

Hi!
You can set the Page Setup using Document.LastSection.PageSetup.
On the first page you can call "sec.AddParagraph();" to leave some extra space to "protect" the image.
You can set paragraph.Format.SpaceAfter to make a single paragraph as big as you need it.
