Cancel Event in RadAsync upload

[prabha]

Hi,

      I am using Rad Async upload with Rad Progress bar in my application. It is working fine.
But While clicking cancel button in Rad Async upload,it showing the progress bar for another 5 mins and then disappears.
1. How can we avoid the progress bar in Rad Async upload cancel event.
2. How can we capture the cancel event in Rad Async upload?

I am using default cancel and remove button in Rad Async upload.

Thanks
Prabha
