How to break file data in differend links

Question

Hi,
   I am bit new to ASP .net can some one help me?
I am reading from a text file and showing the content on the Web page.  Now if the file is quite big then the my page size will also increase which will become problem to scroll down and read.

              I want to create number of links like 1 2 3 4 ....... on the same page depending on the content size and if I click on the link my page should show me the new next content.
Thanks in advance.
