Can someone help me?
When the constructor DocEditPage is called, the variables file, file name and
content type are null. These variables set to be later. But the panel is not
refreshed.

Betreff: panel can not be refreshed
Hello,
I have implemented iframe and can view documents. Unfortunately, only in the
class MyPdfResource hard-coded filename (example: private string filename =
"test.pdf";) can be displayed.
The files can not be refreshed. I hope someone can help me.
greetings, Mehmet
