show asp.net progress bar for multiple operations

I need to show asp.net progress bar for three operations on webpage. First,when file upload the progress bar should show 33 % and message 'file upload started'. Once uploaded it should show message 'validating file data' and progress 66%. At third round, it should show 'automatching data' with 99%.

I have three methods that will be called one by one. I googled a lot but couldn't find a solution for this type of problem. Can someone please help?
