Export Entire User Input Form to PDF in C#

Question

I have a form that captures general user information like FirstName, LastName etc.
When user is done entering all information and clicks on the button Button1; I need to export the entire form to PDF.

Is there a way to do it?

First Name: <user Input> City: <user Input>
Last Name: <user Input> State: <user Input>
Address: <user Input> Zip: <user Input>

[Button1]

Answer 1

I do not see iText7.pdfhtml anywhere in your references screenshot.

As far as I can tell you still have not installed the NuGet package. It's possible that there are build errors which stops the package installation. Usually build errors are very clear. Anyway, fix the build errors first. Once the project builds successfully then install iText7.pdfhtml.

Pay closer attention to the details.

Here is the code; copied form the link

    public System.Collections.ICollection GetFormFields(Stream pdfStream)
    {
        iTextSharp.text.pdf.PdfReader reader = null;
        try
        {
            PdfReader pdfReader = new PdfReader(pdfStream);
            AcroFields acroFields = pdfReader.AcroFields;
            return acroFields.Fields.Keys;
        }
        finally
        {
            reader?.Close();
        }
    }

    public void CreatePdf(String src, String dest)
    {
        ConverterProperties properties = new ConverterProperties();
        properties.SetCreateAcroForm(true);
        HtmlConverter.ConvertToPdf(new FileStream(src, FileMode.Open, FileAccess.Read),
            new FileStream(dest, FileMode.Create, FileAccess.Write), properties);
    }

I have no idea what link you are referring to and there is no indication how you are calling the two methods.

Below is an example that overrides the Web Form's Render() method.

protected void Button1_Click(object sender, EventArgs e)
{
    returnPdf = true;
}

protected override void Render(HtmlTextWriter Writer)
{
    string Content = string.Empty;
    MemoryStream pdfStream = new MemoryStream();
    if (returnPdf)
    {
        using (StringWriter stringWriter = new StringWriter())
        {
            using (HtmlTextWriter HtmlTextWriter = new HtmlTextWriter(stringWriter))
            { 
                base.Render(HtmlTextWriter); 
                HtmlTextWriter.Close();

                // get the page content  
                Content = stringWriter.ToString();

                //Get a PDF stream
                MemoryStream htmlStream = new MemoryStream(Encoding.UTF8.GetBytes(Content));
                HtmlConverter.ConvertToPdf(htmlStream, pdfStream);
            }
        }

        // render the PDF content
        Response.ContentType = "application/pdf";
        Response.BinaryWrite(pdfStream.ToArray());
        Response.End();
        Response.Flush();
        Response.Clear();
    }
    else
    {
        //Render HTML content
        using (StringWriter stringWriter = new StringWriter())
        {
            using (HtmlTextWriter HtmlTextWriter = new HtmlTextWriter(stringWriter))
            { 
                base.Render(HtmlTextWriter); 
                HtmlTextWriter.Close();
                Content = stringWriter.ToString();
            }
        }
        Writer.Write(Content);
    }
}

If the button is clicked a PDF is returned otherwise HTML is returned. I'm not sure if this is what you are trying to do exaclty.

Answer 4

Where is "returnPdf " defined?

Error: The name returnpdf does not exist in the current context.

I defined a public bool bool returnPdf to get rid of this error but still get the error on HTMLConverter and Encoding

MemoryStream htmlStream = new MemoryStream(Encoding.UTF8.GetBytes(Content));
HtmlConverter.ConvertToPdf(htmlStream, pdfStream);

Answer 5

Yes, I have both installed and added to the project but I get an error in the code:
using iText.Html2pdf

Error: The type or namespace 'iText' could not be found. I use the balloon and it give an option to change it to
using iTextSharp.Html2pdf but it gives a different error when selected.

Which .Net Framework do I need to have for iText7? 4.5 could be an issue.
