creating pdf

Hi manikanth, I'm not sure if you want to create a new PDF from scratch in C# or do you want to use some sort of a template document.
You see this second approach is more common, you could create a word (DOCX) or template (DOTX) document in .NET which will define some place holders and then you can fill them with database data and convert the document to a PDF.
I also used this approach with a help of this .net dll for word and other document type file processing, more specific I used MergeField elements in DOTX file and then execute a mail merge operation in C# to import new data, after that I save the document into a PDF format.
Also just in case if that approach does not suit your needs, here is a sample how to create a new PDF file with DataTable's data:

var dataTable = new DataTable();
 
// ...
 
var document = new DocumentModel();
document.Sections.Add(
    new Section(document,
        new Table(document, dataTable.Rows.Count, dataTable.Columns.Count,
                    (r, c) => new TableCell(document,
                                    new Paragraph(document, dataTable.Rows[r][c].ToString())))));
 
document.Save("New File.pdf");

I hope this helps.
