ASP.Net AJAX UpdateProgress for each content page

Hi,

I have master page and have lot of content pages. I want that to have one update progress panel on master page which can work on each content page for e.g if I click button on Page a so my update progress bar show wait message same if I click button on page b same progress bar show message.

I know I can place update progress bar on each page which can solve my problem but I believe there should be a solution through which I can achieve the above task.

Thank you
