Client Callbacks And Event Handlers

[pbd22]

Hi There.

I think i need some software design help.

I have a page, server.aspx, that starts uploading video files when it
is loaded via hidden iframe by the client. On the same page is an
event handler (below) that produces useful data about the upload
(percent, time, bytes, etc).

MY PROBLEM is that the server.aspx file is being used for video
uploads and I need to create a second polling routine on the client
that polls upload data provided by the onIncrementCall back method. I
can't call server.aspx twice (for two different purposes) in my client-
side querystring.

How do i query the info provided by the event handler when the same
page is being used for video uploads?

Thanks!

You need to do this through asynchronous javascript ... with Ajax or a
second iframe reloading the server.aspx page.

THanks for your response.
I am doing that. Or, that was what I intended.
I guess my question is - can I use the same
page for two different iframe (or ajax) RPC calls?
Server.aspx is used to upload the videos for the
first and return video upload information for the
second. Will two different calls targeting the same
page matter?

Each time a page is called in ASP.NET it is a new instance. So yes, you can
call it multiple times.

Of course you'll need to distinguish each different type of calls - which
can be done with query strings. Or you could create different pages - 1 for
polling and 1 for upload. There are many different ways of doing what you
intend.
