hello,
I created a preciew control to preview the watermark and header&footer,after user changed the value,then update the doc,and my logic is as below:
1.remove old watemark
2.remove old header&footer (yes,user can change both the watermark para and header&footer para in the same form)
3.add header&footer
4.add watermark
5.invalidatepage
i found remove watermark/header&footer and add watermark/header&footer cost almost a minute(my document has only 58 pages).
do you have any suggestion to help me?
the attachmens are part of log file and our preview form.
Why is the operation so slow?

Hello HomerWu,
Well that's because you are doing it like that. Why can't you remove all of the watermarks/HaFs in one go and then add the needed watermarks and HaFs in another go - should be a couple of seconds.
Cheers,
Alex

Hello HomerWu,
Just remove them from all of the pages and add them to all of the pages - that's all.
