Created submision form asp.net ajax how to store in database

Hi I have creted a form for a job submision it has a number of text boxes / date pickers / text edittor and async file uploader, onload it creates a random string and stores it in a text box (this becomes the job id) this id is also used to create a folder (of the same name) to store any file uploaded,
I have tried to store the file location so I can add it to the database but the textbox/lbl remain empty.
Secondly I would like to submit this form to a database I am using asp.net 3.5 with rules / membership / state on sql I would like to be able to post the user role / name as part of the data store if this is possible.
I have attached my code the asyncfileUploader was converted from C# Demo and modified using suggestions found via google.
