What I want is an ASP.net web page (c#) that show a button
The user presses the button
This button press initiates a moderately long background process. I want the page to the show a message saying "running" and the button be disabled.
When the background process ends I want the page to show "Process finished" and the button re enabled.
I have tried using ajax but I am not getting the hang of it.
What is the easiest way to achieve this?
