| Post subject: | Force calculation of calculated field |
Hello, Can anyone tell me if it's possible to ensure that calculated fields are correctly calculated after setting the value of a field with PDFSharp? I read on the internet that it's not possible or really difficult to achieve. I just want to be sure. When I set the value of a field, calculated field have the same value as they did before setting the value. If I set the value using adobe reader, then calculated are updated with new values. Is it possible to have the same behavior when setting the value with PDFSharp? Here is my code. using PdfSharp.Pdf; using PdfSharp; using PdfSharp.Pdf.IO; using PdfSharp.Pdf.AcroForms; private void button1_Click(object sender, EventArgs e) { string fileN4 ="C:\test.PDF"; PdfDocument document = PdfReader.Open(fileN4, PdfDocumentOpenMode.Modify); PdfTextField currentField = (PdfTextField)(document.AcroForm.Fields["TopPos_X"]); PdfString caseNamePdfStr = new PdfString("68,96"); //set the value of this field currentField.Text = "68,96";// caseNamePdfStr; //currentField.Value = caseNamePdfStr; // Save the document... document.Save(fileN4); } |
