File Upload/Download In CAF

Hi All,
I have a requirement where I need to upload file using file up-loader.And need to keep uploader pointing to the same file in case of there is some refresh on page until the page is finally submitted.
File Uploader is kept in a Async Table row where Table is adding more rows on clicking add new row.So need to keep all file previously selected and refresh the table.

Thanks in Advance.

Thanks Baharul
