Hi Tarek,   
  
Thank you for the details.   
  
We have modified the sample to achieve your requirement using the below ways,   
  
·      Custom formatting – While setting SetDefaultAppearance to true, the respective values are preserved fine. 
·      Calculate sum value automatically – we do not have support to calculate the sum value automatically. However, we can achieve this as manually.   
  
Please refer the below code snippet for more details,   
  




//Load PDF document  
FileStream docStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read);  
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);  
  
var loadedForm = loadedDocument.Form;  
  
float total = 0;  
  
loadedForm.EnableXfaFormFill = true;  
loadedForm.DisableAutoFormat = false;   
loadedForm.SetDefaultAppearance(true);  
  
foreach (PdfLoadedField field in loadedForm.Fields)  
{  
    Console.WriteLine($"{{Type: {field.GetType().Name}, Name: {field.Name.Trim()}, ObjectID:{field.ObjectID}}}");  
  
    switch (field)  
    {  
        case PdfLoadedTextBoxField pdfLoadedTextBoxField whenpdfLoadedTextBoxField.Name != "A":  
            pdfLoadedTextBoxField.Text = 5.22M.ToString("C2", _cultureInfo);  
            total += 5.22f;  
            break;  
  
        case PdfLoadedTextBoxField pdfLoadedTextBoxField whenpdfLoadedTextBoxField.Name == "A":  
            pdfLoadedTextBoxField.Text = total.ToString("C2", _cultureInfo);  
            break;  
    }  
}  
  
//Save and close the document  
MemoryStream stream = new MemoryStream();  
loadedDocument.Save(stream);  
loadedDocument.Close(true);  
  
  
Sample: https://www.syncfusion.com/downloads/support/forum/163008/ze/NETCoreConsoleApp1894998367   
Output document: https://www.syncfusion.com/downloads/support/forum/163008/pd/Output-1941340527   
  
Please try the above sample in your end and let us know the result.

First, I want to thank you for your interest.

The error is still present in version: Syncfusion.Pdf.Net.Core 18.4.0.44.

But it works fine with this version: Syncfusion.Pdf.Net.Core 17.1.0.52.

However, the problem of the calculated fields was not solved in the old version or the new version.

I expect you to solve this problem in the near future version.

In short, the formatting assigned to the field or SUM is not applied. If you go back to your example and make the number greater than a thousand, you will have another problem.In the end, I will now make two copies, a copy to be filled out automatically, and the copy that contains the formatting, I will make it manually for the user to fill in.This means that our program has failed.Thank you for your cooperation in advance.Regards,
