Display input checkbox in itextsharp generated pdf how please?

Question

I have a requirement that I need to display checkbox on pdf document generated using itextsharp. However, as itextsharp doesn't support html input tag, the checkboxes did not appear on my page. I use asp.net checkboxlist control and I am thinking about adding background image to display the checkbox as checked or not checked, but for some reason, I could not get it to display still. Here is my code:

 Protected Sub Checkboxlist1_DataBound(sender As Object, e As EventArgs) Handles Checkboxlist1.DataBound
    If test <> "" Then
        Dim checklist As List(Of String) = ReturnListofStringClass.ReturnChecklistListOfString(test)

        For i = 0 To Checkboxlist1.Items.Count - 1
            For Each id As String In checklist
                If Checkboxlist1.Items(i).Value = id Then
                    Checkboxlist1.Items(i).Selected = True
                    Checkboxlist1.Items(i).Attributes("style") = "background: url(http://renegadeox.com/img/on.png) no-repeat red; height:300px; color: blue; font-size:20px;"
                End If
            Next
        Next
    End If
End Sub

The background color applied but not the image. Thanks for your help.

Are you using HTMLWorker? If so, CSS isn't supported, switch to XMLWorker. However I don't believe that [background images are supported in XMLWorker](http://demo.itextsupport.com/xmlworker/itextdoc/CSS-conformance-list.htm) yet either. Also, HTMLWorker doesn't handle form fields and I believe (but could be wrong) that XMLWorker still doesn't either. Do you need a checkbox that's interactive (clickable) or just an image? The latter should be easy, just put an actual `IMG` in there. For the former, you might have to [write your own tag processor](http://stackoverflow.com/a/24498296/231316) — Chris Haas, Jul 21 '14 at 13:25
Chris, it's the later. I just need an image not interactive one. How can I put an image in there. Please refer to my above code. That's how I iterate through the checkboxlist. Thanks — ryan, Jul 21 '14 at 21:05
Chris, I found this link:http://stackoverflow.com/questions/14812955/how-to-add-image-background-to-pdf-for-every-page. Looks like background image is supported (perhaps not through CSS) but how I can add this in the place where the checkbox is supposed to be. Thanks — ryan, Jul 21 '14 at 21:31

Perhaps this will help.

Protected Sub Checkboxlist1_DataBound(sender As Object, e As EventArgs) Handles Checkboxlist1.DataBound
If test <> "" Then
    Dim checklist As List(Of String) = ReturnListofStringClass.ReturnChecklistListOfString(test)

    For i = 0 To Checkboxlist1.Items.Count - 1
        For Each id As String In checklist
            If Checkboxlist1.Items(i).Value = id Then
                Dim t AS string= Checkboxlist1.Items(i).Text
 Checkboxlist1.Items(i).Text = "<img src='http://renegadeox.com/img/on.png' style='width:10px; height:10px;' alt='' title='' />" & "  " & t

            End If
        Next
    Next
End If
End Sub

Cheers
