 {
     doc.LoadFromFile(MyFileTemplate);
     PdfFormWidget formWidget = doc.Form as PdfFormWidget;

     (formWidget.FieldsWidget["UserID"] as PdfTextBoxFieldWidget).Text = Username;
     (formWidget.FieldsWidget["Name"] as PdfTextBoxFieldWidget).Text =Name;
     (formWidget.FieldsWidget["Address"] as PdfTextBoxFieldWidget).Text = Address;

     doc.SaveToFile(MyFilePath);

Answer 2

It seems that your method only works for the textbox created by the Adobe. If you draw the text using Spire.Pdf, please change the code as below:

PdfForm formWidget = doc.Form as PdfForm;
PdfTrueTypeFont font = new PdfTrueTypeFont("My Font Name", 10f);
(formWidget.Fields["Address"] as PdfTextBoxField).Font = font;

Now your code works well with the newest hotfix(Spire.pdf3.9.82), you can try it.
