Hi,

if i fill fields and then i want to fix them with

PDFLibrary.UpdateAndFlattenFormField(index);

If i do so, the fields y position is to low...

if i use

PDFLibrary.SetFormFieldReadOnly(index,1)

the position of the fields are correct, but if i use

PDFLibrary.RenderPageToFile(DPI, ViewPrintPageNum, 1, fn);

the fields are not visible!

Can you help me please?

Ciao
Stefan

My code uses SetRenderOptions(1,1) after FlattenAllFormFields, even though it says this is the default. But I can't now remember when or why I added it. Other things to try are SetFormFieldVisible for each item in the formfield count and SetNeedAppearances(0). I have always found rendering all types of form field a bit of a challenge! Experiment until it works, but the next different PDF may be your next issue.

I don't want to test with more problems...

My solution:

I delete the formfield ans place a fixed text at this position, so i don't need UpdateAndFlatten and not SetFormFiledReadonly!
