Hi,
I am using trail version aspose pdf for .net for generating pdf file from filestream of aspx file which g enerates html filestream content and i am trying to generate pdf from this.
My problem is with aspose’s output pdf file is it is generating pdf file with empty blank page in the final pdf file.
I am attaching the output of final file for your reference and code which i am using for this requirement as well.
protected void btnPrint_Click(object sender, EventArgs e)
{
try
{
var rows = gvContactList.Rows;
// Instantiate an object PDF class
var pdf = new Pdf();
var doc = new Document(pdf);
// add the section to PDF document sections collection
var section = pdf.Sections.Add();
// Create Header Section of the document
Aspose.Pdf.Generator.HeaderFooter header = new Aspose.Pdf.Generator.HeaderFooter(section);
section.OddHeader = header;
section.EvenHeader = header;
//Create an image object in the section
Aspose.Pdf.Generator.Image image1 = new Aspose.Pdf.Generator.Image(section);
image1.ImageInfo.File =Server.MapPath(ConfigurationManager.AppSettings[“PDFHeaderImagePath”].ToString());
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Gif;
header.Paragraphs.Add(image1);
// Create a Footer Section of the document.
Aspose.Pdf.Generator.HeaderFooter footer = new Aspose.Pdf.Generator.HeaderFooter(section);
section.OddFooter = footer;
section.EvenFooter = footer;
// Create a Text object
Aspose.Pdf.Generator.Text txt = new Aspose.Pdf.Generator.Text(“Page: ($p of $P ) “);
footer.Paragraphs.Add(txt);
for (int i = 0; i < rows.Count; i++)
{
var chkBox = rows[i].FindControl(“chkBoxPrint”) as CheckBox;
var rowNo = gvContactList.DataKeys[rows[i].RowIndex].Value.ToString();
if (chkBox != null && chkBox.Checked)
{
var strWriter = new StringWriter();
byte[] data = AECrypt.EncryptWithSymmetricAid(rowNo, PublicKey);
var navistring = Convert.ToBase64String(data);
Server.Execute(string.Format(”~/pub/PDFGenerator.aspx?id={0}”, navistring), strWriter);

//Create text paragraphs containing HTML text
Aspose.Pdf.Generator.Text txt1 = new Aspose.Pdf.Generator.Text(strWriter.ToString(), info);
txt1.IsFitToPage = true;
txt1.UseTextInfoStyle = true;
// enable the property to display HTML contents within their own formatting
txt1.IsHtmlTagSupported = true;
section.PageInfo.PageWidth = Aspose.Pdf.Generator.PageSize.A4Height;
section.PageInfo.PageHeight = Aspose.Pdf.Generator.PageSize.A4Width;

// Assign the marginInfo instance to Margin property of section.PageInfo
section.PageInfo.Margin = marginInfo;
//Add the text paragraphs containing HTML text to the section
section.Paragraphs.Add(txt1);
}
}
//// Assign a security instance to Pdf object
//pdf.Security = new Security();
//// Set the master password for the PDF document
//pdf.Security.MasterPassword = null;

// Open the pdf file as stream in the browser window.
var stream = new MemoryStream();
pdf.Save(stream);
