PDF-form with iTextSharp

Question

How can I create fillable PDF file in iTextSharp. At the moment, I can create a pdf file with text in it, but I'm struggling with the creation of fillable fields. Any help or sample code would be appreciated.

Answer 1

Harder to make PDF-form of third-party software such as Adobe LiveCycle Designer, than iTextsharp. You just need to put some text fields, check boxes, radio buttons, or as needed on your form, set the font, font size and type of data.

Check all field names (for example, "TextField1", etc.). Create a new Web form that contains some text fields, which supply the data in these fields.

You can easily fill out this form by using code, as shown below:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.IO; using iTextSharp.text; using iTextSharp.text.pdf; public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { var reader = new PdfReader(Server.MapPath("~/Emptyform.pdf")); var output = new MemoryStream(); var stamper = new PdfStamper(reader, output); stamper.AcroFields.SetField("TextField1", TextBox1.text); stamper.FormFlattening = true; stamper.Close(); reader.Close(); File.WriteAllBytes(Server.MapPath("~/Filledform.pdf"),output.ToArray()); } } 

Answer 2

Try the following:

 AcroFields fields = pdf.AcroFields; fields.SetField("field_1", "1"); fields.SetField("field_2", "2");
