like changing views using tabs when i click a tab it changes content very fast than i used to in my web applications using Asp.Net and Ajax Control Toolkit
and also a very quick paging in repeaters or grids than i ever developed in my web apps
like this website [URL] i need to know which technology used to achieve this this website is developed using .net
so
but i need to know is this needs another technology to learn (from where can i learn it)

is it MVC
also i want to know if MVC is better than asp.net + ajax in concern with performance

I am using the tab control and basically I have 4 buttons. Each button will load a seperate ascx control into a brand new tab. After about 4 tabs, since it has to regenerate all 4 tabs, the speed in order to add tabs just becomes too long for my tastes. Is there any way to remedy this and make it go faster?
EDIT2:Using Internet Explorer 7.0 and 8.0
EDIT: Some Code, I store the i in viewstate and loop through this every time for each panel per regeneration
private void BuildNewTab(int i)

TabPanel newPanel = new TabPanel();[cod]....
When I'm building my web project it takes about 20 seconds to compile. Then when I try to browse to a web page in project, asp.net does its runtime compilation(another 20 seconds). I know I can't escape these steps because thats how asp.net works, just want to see if anyone has some kind of optimization to make these builds faster.

if there is an idea how make this query better, i will glad to know.
I have this query for getting data through Entity Framework, which works today. Thing is, i want to create the query dynamically, i.e build it up in blocks, but i can't figure out how exactly to do it. I believe if i can somehow save one of the values that i retrieve in the beginning i can do it, but now i retrieve it twice (probably a bit slow as well? Unless the compiler fixes it before quering). Makes sense? Here is the LINQ:
[code]....
I.e based on if various variables have values.
is it possible to make a Linq query dynamic in the following pseduo code (to show what I'm trying to do)
[Code]....
where a2 and a3 and a4 are being populated from user controls and only one will apply. So query is done by state, zip or by city, but not by more than one, so the other two would be null. So the operator is really "OR" but I haven't found anything on a "or" or "whereOr" operator.
