The user clicks a button and in the code-behind there is a very long process in which I am adding an Item to the ListBox to update the user of what step the process is currently in. By the time the process is done there are 40 new Items but they are only displayed when the process is done. I want the the Item to be displayed immediately for the user in an Ajax kind of way.
I added the RadAjaxLoadingPanel and RadAjaxPanel to my page but still the Items were displayed after the completion of the long process instead of immediately.
Any guidance on this would be appreciated!
