Maybe I should ask this in asp .net, but it seems there are many people reading at here, so .... Sorry for any inconvenience.

I have a webform using asp .net. In the form, user clicks a button, then it creates a thread which does some computation. It will take a while to finish the computation. How can I change a label on the webform, so that it will show the progress?

Right now, I use a timer. Every 5 seconds, check a value, then show the value in the label. How can I force the webform to postback?

I'm using asp.net 1.1, so can't use ajax. Or ajax support 1.1?


thanks
