Radio button values

Aspose.PDF Product Family
1

I’m attempting to read the value of a radio button on an existing document with Aspose.Pdf version 8.8. The document was created by Adobe LiveCycle with reader extensions and contains approximately 50 fields.


Aspose.Pdf.Document.Form.Fields property (only contains 3 digital signature fields)
Aspose.Pdf.Document.Form.GetField method (returns values for fields except radio buttons)
Aspose.Pdf.Facades.Form.ExportXml method (result includes values for all fields except radio buttons)
Aspose.Pdf.Facades.Form.GetFieldFacade method (no suitable parameter value found)
Aspose.Pdf.Facades.Form.GetButtonOptionCurrentValue method (no suitable parameter value found)

Please see the attached form. This is a stripped down version of the actual form that demonstrates the problem.

var form = new Aspose.Pdf.Facades(path)
form.GetField("changeMgmt[0].page1[0].frmInformation[0].txtRequestorName[0]) --> "Last, First"
form.GetField("changeMgmt[0].page1[0].frmInformation[0].rdbChangeType[0]) --> "" (value expected)

Hi Jason,


Thanks for sharing the resource file.

I have tested the scenario and have observed that value for changeMgmt[0].page1[0].frmInformation[0].txtRequestorName[0] form field is being returned as First, Last. Whereas no value is being returned for changeMgmt[0].page1[0].frmInformation[0].rdbChangeType[0] field. As per my observations, the second field appears to be a radio button field. Before we proceed further with the resolution of this issue, please confirm that you are also experiencing similar problem.

[C#]

var form = new Aspose.Pdf.Facades.Form(“C:/PDFTEST/CR_Form_extended_signed.pdf”);<o:p></o:p>

Console.WriteLine(form.GetField("changeMgmt[0].page1[0].frmInformation[0].txtRequestorName[0]")); //--> "Last, First"

Console.WriteLine(form.GetField("changeMgmt[0].page1[0].frmInformation[0].rdbChangeType[0]")); // --> "" (value expected)

Yes. That is exactly the observed behavior. This just may be the wrong approach to determine the value of a radio button. I’m open to other options.

We found a workaround using a different product. A script in Adobe Acrobat Pro exported the documents to HTML and the results were parsed with a .NET application. Thanks for looking into this.
