you already have the data saved on the client machine in the textbox where it is displayed... all you need to do is make sure it doesnt reload for 10 seconds... like this:

call "ReloadTextVal()" on the page load... you can do this by placing onload="javascript:ReloadTextVal();" as an attribute in the <body> tag. Each time the function finishes running it will set a timeout to be called again in 10 seconds...

function ReloadTextVal()
{
///put your
/// ajax call
/// code here...

//call this function again in 10 seconds
window.setTimeout("ReloadTextVal()",10000);
}
function AjaxResponseCall()
{
document.all.TEXTBOX_FIELD.value="VALUE RETRIEVED BY AJAX";
}
