Optimizing performance of large ASP.NET applications

I'm building a asp.net web application with lots and lots of controls and huge volumes of data. My application is very slow and it is taking a large amount of time to load the data into the .net controls like grid, tree view etc. I also have some ajaxified pages and controls in my application. I want to reduce the page load time in eac开发者_JS百科h postbacks.

What are the standards/best practices to be followed while developing large asp.net applications?

Thank you.

• Cache certain data, either in the application or in the database (thus breaking normalization but it's okay)

• Retrieve the minimum subset of data you really need. Don't pull 10000 records from the database into a grid to only display 50. Query for exactly 50.

• Mimimize the amount of server controls and dynamic markup creation. Replace what you can with passive HTML elements.

• Switch off the view state, which can potentially expand pages to many megabytes in size. Pull the data from the database on each request (in combination with caching strategies).

You Can use JQuery to retreive the data from database which is much better than using ajax. Check this http://www.codeproject.com/KB/webservices/JsonWebServiceJQuery.aspx
