It seems like regularly something comes up in the programming world that is requested by a client that should be easy, ends up proving to take more time, more money or both. So it is nice to find a solution to a problem that IS easy. This article is to show you how easy it is to use ASP.net web form to open up a PDF, set a value on a form and then send it back to the user’s browser. I have attached the project below if you want to download it. The first thing you need to do is go download iTextSharp.dll. I will be using visual basic (vb) for this project.
Step 1: Start VS 2012
Step 2: Create a new project
Step 3: Add the iTextSharp.dll reference that you downloaded from above.
Step 4: Create a new web page
Step 5: Add this to the code behind for the .aspx page created in step 4
Dim var As New iTextSharp.text.pdf.PdfReader(Server.MapPath(“~/SamplePDF.pdf”))
Dim output As New MemoryStream()
Dim stamper As New iTextSharp.text.pdf.PdfStamper(var, output)
stamper.AcroFields.SetField(“Name”, “Fred Flinstone”)
stamper.AcroFields.SetField(“chk_Cash”, “Yes”) ‘Match its export value
‘ Form fields should no longer be editable
stamper.FormFlattening = True
Response.AddHeader(“Content-Disposition”, “attachment; filename=YourPDF.pdf”)
Response.ContentType = “application/pdf”
Although this is very simple application you can take it and run with it. You can download the project from here.
