File Upload within Modal Pop-up

I am having a problem with file upload within a Modal Popup.  I understand the file upload gets its value on the postback event.  How do I make it so that file upload retrieves its value without the Modal Popup closing.  I do not want to use the show function.

What has a general 'modal popup' got to do with a general 'file upload' and a 'postback event' ?

I'm using the Ajax Modal Popup within a update panel which is a custom control.  The control does not capture the information in the file upload control and is null unless a postback occurs.

I used the asynchronousfileuplod control and OnUploadedComplete event to obtain the file without completing a postback.
