Hi
I want to create a quick launch links based on user login.

By adding code in default.master, I can create links for a user A.

When User B logs in, it shows the links of user A. When i refresh the browser of B, it shows the links of User B.

When i refresh User B browser, it shows links of User B.

I want to retain the links of each user on their login, till they logout.

If this is possible what are the things, i need to keep in mind when i'm developing this.

Awaiting your reply.

Thanks
Prasad

Thanks hagrin. For us IT types who aren't as familiar with C#, would it be possible to post the code project for this? Not knowing much about making Custom Web Parts, I'm not exactly sure what to do with this cost specifically :)
