How to optimize app for performance

[sama123]

I have an asp.net application written in C# and need some help to fine tune it for better performance. All pages with in this web application have horizontal tab, left vertical menu panel , footer and header. Left menu panel changes as per top tab selection.

In my current code - tab, left menu panel, header and footer are loaded for every page. Is it possible to load these things once per tab selection and then change content area ONLY when user navigates to different pages from menu panel?

Hi sama123,

You could try using AJAX to provide a better user experience. Read up about the Update Panel.
Using this method you can refresh the content section only, without the need for a post back.

Hope this helps.
