How to prevent textbox for being refreshed

[reshma]

Hi,

I have place an adrotator control on the webform and a textbox control. I have the meta tag so that the image in the rotator control changes for every 5 seconds. The problem is when the rotator is getting refreshed, image is changing but the data in the textbox is also lost.

My question is how to prevent the data from being lost, when the page gets refreshed??
I have set AutoPostback Property of textbox to true. But still its not working.

Thanks in advance.
