Hi,

I'm using pdfium on WinForms.
I have created a PDF which contains form fields.
First I copy the template to a new filename.
I load the file using LoadDocument() and it displays correctly
I then fill in all of the form fields by typing into them and I click Save.
A save method is then called which saves the PDF back to the file .Save(SaveFlags.NoIncremental)
However, not all of my changes are being saved back (e.g. the last field remains empty even though I entered text into it before saving).
Can you advise the correct methods I should be using for this scenario?

Thanks,
Joe

Hi Paul,
I think I've just figured out a workaround to resolve this issue.
On further testing it seems that it's always the last form field that doesn't get saved.
However, this only happens if I leave the cursor in this field when clicking save.
If I manually click into some other field it works.
I found a method in the API that seems to do this without the user needing to click away from the last field - Document.FormFill.ForceToKillFocus()
If I call this method before the Save() all seems to be OK.

Thanks,
Joe
