Hi

I think you need do 2 things.

1. You need to create a UserControl.

This control have many web control like: label1,label2, textbox1 etc. And this control will help you to display your message.

2.If you know how to control the formate, use CSS to this UserControl. If you want to retain the default formate when the document uploaded by other pepole.(like google books) You need Flash
