Spire.PDF Read-Only Form Fields

[djacobs111]

Hi,
Spire.PDF does not include read-only form fields with this loop;

Code: Select all

 PdfFormWidget formWidget = pdfObj.Form as PdfFormWidget;
 if (formWidget == null)
 {
     return listOfTags;
 }

 for (int i = 0; i < formWidget.FieldsWidget.List.Count; i++)
 {
     PdfField field = formWidget.FieldsWidget.List[i] as PdfField;
....


Is there any workaround to replace read-only field texts?

Thank you

Hello,

Thanks for your inquiry.
How did you set the read-only attribute for the form field? Did you use "doc.Form.IsFlatten = true" or "field.ReadOnly = true"? The first method will delete the field and only keep the content in the field, so the code cannot get the field in the result document. The second method will not delete the field, and the code can still get the field. Or you can provide us with your pdf file and we will investigate further. You can upload it here as an attachment or send it to this email address: [email protected]. Thanks in advance.

Hello,

Thanks for you file.
I tested your case with the latest Spire.PDF Pack(Hot Fix) Version:10.6.25, but did not reproduce the problem you mentioned. I used the following code to read two read-only fields in your document. In addition, I modified the content in the read-only fields. I have uploaded the result document as an attachment for your reference. If the issue still exists, please wirte back to us.

Code: Select all

PdfDocument pdfDocument = new PdfDocument();
pdfDocument.LoadFromFile("Form_SSA-1696_Page_3.pdf");
PdfFormWidget formWidget = pdfDocument.Form as PdfFormWidget;
for (int i = 0; i < formWidget.FieldsWidget.List.Count; i++)
{
    PdfField field = formWidget.FieldsWidget.List[i] as PdfField;
    bool readOnly = field.ReadOnly;
    // Print the names of read-only fields
    if (readOnly)
    {
        field.ReadOnly = false;
        if (field is PdfTextBoxFieldWidget)
        {
            PdfTextBoxFieldWidget textBoxField = field as PdfTextBoxFieldWidget;
            //Get text of textbox
            textBoxField.Text = "new text";
        }
    }
}
pdfDocument.SaveToFile("Res.pdf");
