Post subject: | Combobox SelectedIndex is not working |
I am trying to edit the a PDF But This has China as default value and when I try to set the selected index and save the file China is shown as value, Also for a file if it doesn't have any default value it always shows empty value. Below is my code PdfDocument pd = PdfReader.Open(sourceFilePath, PdfDocumentOpenMode.Modify); var pdfFields = pd.AcroForm.Fields; ((PdfComboBoxField)pdfFields[i]).SelectedIndex = 0; //i is index generated when we iterate pdfFields. Can anyone please try to edit some PDF using PDF sharp in Code and let me know what am I dping wrong. I have generated editable PDF from http://www.pdfescape.com |

Had the same issue, this ultimately worked for me: Code: var comboBox = field as PdfComboBoxField; PdfArray indexElement = (PdfArray)comboBox.Elements["/I"]; indexElement.Elements[0] = new PdfInteger(4); comboBox.Value = new PdfString("Five"); This will set the value properly for display in Acrobat itself. For some reason, just setting Value normally would work but only in less exacting viewers like Chrome or Edge. |
