Hey Ankit,
AFAIK, you wont get to know the size of the file unless you transfer it to
the server. But from the client side you can restrict the file extension by
extracting the file name as follows :
final FileUpload upload = new FileUpload();
upload.setName("uploadFormElement");
absolutePanel.add(upload,8,37);
String fileNameVal = upload.getFilename();
You can put appropriate check to ensure that certain kind of files alone
can be uploaded.
HTH,
Regards,
Abhi
