Before the page has been loaded, use the selected attribute.

Not Selected
Also Not Selected
Selected

If you want it during run time; then use javascript.

document.getElementById('selectbox').selectedIndex = 2;

If at first you don't succeed, you're not Chuck Norris.

Thanks for your fast reply,I want the dropdown index should be changed during runtime,I dont want to assign the static value as 2, For the next if i select 3, then it will still remain in 2, I want the index to be changing as per user input.

It was just an example. Obviously you would put it in a function.

function changeSelectedIndex(id, index)
{
document.getElementById(id).selectedIndex = index;
}

changeSelectedIndex('selectbox', n);

Obviously, n can be any index (number) of your choice.

If at first you don't succeed, you're not Chuck Norris.

HI, Make a bit clear,changeSelectedIndex('selectbox', n); the 'n' is user choice or it changes dynamically at runtime.I want the index should be changed dynamically at runtime.I dont want to edit in code.

Well I don't know how you're calling the index change so all I can do is put a variable there!
