Thanks for your reply.

I attached a single web project which mimics my production site. I just have an upload control and a generic handler. i got the code you posted working on my end as far as showing the filesize data on the control. So i then hooked up the Handler to it the same way i have it setup on my production control and the file size data then disapeared. it appears i am manually setting the UPLOADURL property and pointing it to the uploadhandler. this was the only way i could get the control to send off the files. So when i remove the UPLOADURL property, and select a file, i can see filedata, but can not upload.And the opposite is true:  if i add the property, i can upload but cant see the filedata. 

Am i misunderstanding the function of UPLOADURL vs PROGRESSURL?

the handler never gets called (For me) if i just have the progressurl.property set, but does get called if i set uploadurl.

 (which leads into not understood (yet) how the progress bar , progressurl.property, and the upload handler all work together)

Followup :

ive been playing around more this afternoon and have noticed a few things i've misunderstood about using this control. 

1) the uploadURL doesnt appear to be a property im suppose to be using

2) the reason progressurl was not calling the handler was b/c in my web config i did not have the full path to the handler. it was looking on the root when in fact i had it in a subfolder. once i corrected the path, and removed the uploadurl property, the handler was getting called by the progressurl. (cool) thats the first. (however i'm still not seeing filesize data). regardless, ive got a bigger problem...

3) everything i wrote in my handler is not out the window as i was checking for imcoming files in the context.request.files[] array from the uploadurl property. but now that progressurl is calling the handler properly, i feel like im back at square one with understanding how this control works.

 'what am i looking when the handler is being called?' How do i manage the progress of the file upload? i dont fully comprhend how to use the UploadProgressManager class .

im beggining to isolate more

if the handler isnt specified, it uses the local upload folder at which point everything functions perfectly (See the attached project). 

but when i specify the handler, i get no file stats to start, and im guessing that i have to manage the progress info and file size and whathever you manually to the control? 

yes i am trying to use a custom httphandler. i've read that article before and its not very helpful as theres no example and nowhere explaning how to use UploadProgressManager in the httphandler.

using the control for local upload, i've got working. thanks. but i need more help with setting up the handler.

Hello Adam,

Thank you for the update.

Please let us know if you need further assistance.

ill take a look at the FileUploaderDesigner  class today and get back to you. thanks

Hello Adam,

By Source code I meant that of the controls themselves.

For example inside FileUploaderDesigner class you can see how this handled is added.

IGUploadStatusHandler.ashx also is the default value of the ProgressUrl

You can see the implementation after downloading the source code of the controls.

Let me know if you need further assistance

what i dont understand is that in all your samples, you list this handler IGUploadStatusHandler.ashx file , but no where is it defined or shown handler code. i've looked at all of the sample code for the upload (we have a license and all the example code) but nothing directs me in actually implementing a handler with this control. i did discover the UploadPRogressManager.instance prior to your post, but im still not clear on how to 'fully' manage the control with a handler. i need some very specific handler code examples.
