Query: refresh the list item in a list box on a time interval.

[achio84]

Hi all,

I'm a newbie in .Net programming. I'm developing a web application that has a listbox containing more than 1000++ items. This listbox is dynamic as the content will change on a time interval (e.g every 5 seconds). I tried to compare the list items and make a change if there is a need using for loop and if condition. I even tried using ajax. But then, when i get the data pass back from ajax function, i also need to made comparison. As the items are huge in amount, it cost some delay (quite significant) in my application. Is there a way for me to repopulate the "large" listbox?

Regards,
achio.
