i'm using this control to upload binary files to our webserver. the problem is, how do i do client side processing BEFORE the file gets uploaded. while i'm debugging the server code, i see that by the time i get to a page_load, the file has already been uploaded. what i want to is some verification on the file the client selects with this HtmlInputFile control before he sends it. i was thinking there's gotta be some event on the htmlinputfile control that i can register that gets run before the file gets uploaded, but i don't see it. any clue?
