You can't, and you don't want to. You can't, because javascript doesn't provide any way to read the contents of a file that is stored locally. You can't read the http header info when the browser submits a multi-part post request. There just isn't a way to do it (unless you are willing to write some Flex code to compile a SWF file for Flash Player 10)..
You don't want to, because client side validation is no validation. It can easily be bypassed. You'd have to perform the check on the server anyways, so why bother with client side validation at all? --Sri On 11 May 2010 16:48, GWT Groups <[email protected]> wrote: > > Hello Friends > > I required your views...... > > " Can we check uploaded file Size at client side in GWT by Reading the > "header info" of the file?
