Re: Uploading file input clearing on postback

Well, you cannot check the size because your code does not get invoked until
the entire file is downloaded. You can increase the max size by changing
the maxRequestLength attribute in the machine.config.

One thing I have never done, but you can try, is to see if the error event
in the global.asax can trap that error.
