I want to have a feature for my website which can print the page contents as PDF. I tried a few option for this but the best match was wkhtmltopdf as it also handle multilin

Answer 1

WORKING CODE: I resolved the issue by calling the PrintArticle.aspx from MainPage.aspx, When user clinks on the lnkbtnDownload link Button it will call the page PrinteArticle.aspx (Print Article Page is a simple page which show article title, date and Article Description) and pass the HTML to the code below which will then print it as a PDF file

   protected void lnkbtnDownload_Click(object sender, EventArgs e)
    {
        string url = "PrintArticle.aspx?articleID=" + Request["articleID"] + "&download=yes&Language=" + Request["Language"];

        string args = string.Format("\"{0}\" - ", "http://xyz.net/" + url);
        var startInfo = new ProcessStartInfo(Server.MapPath("bin\\wkhtmltopdf.exe"), args)
        {
            UseShellExecute = false,
            CreateNoWindow = true,
            RedirectStandardOutput = true

        };
        var proc = new Process { StartInfo = startInfo };
        proc.Start();

        string output = proc.StandardOutput.ReadToEnd();
        byte[] buffer = proc.StandardOutput.CurrentEncoding.GetBytes(output);
        proc.WaitForExit();
        proc.Close();
        Response.ContentType = "application/pdf";
        Response.AddHeader("Content-Disposition", "attachment;filename=download.pdf");
        Response.BinaryWrite(buffer);
        Response.End();
    }

I am passing other parameters as query string like articleID, Download, Language etc..
