    I have two asyncupload controls on one page, each calls the same custom "FileHandler" which uploads the file to a database. How can I determine the ID of the asyncupload control that calls the handler from within the handler process code?

    Hi Ric,

    You could handle the OnClientFileUploading event and attach query string parameters to the request. Please review the following help article how it should be implemented.
