I am trying to use the RadAsyncUpload to upload a file, the file does get uploaded but it is uploaded as soon as it is selected and the OnFileUploaded event is never fired. I have tried everything in the following links and none have worked: link1, link2, link3, link4. The .aspx file is quite large and so I will try to give all the important information without showing all lines of html. The uploader is in a radpane whose visibility is set to false until the user makes a selection, that radpane is nested within mutiple radpanes and splitters, all of which are inside an asp Panel. I am using the RadAjaxManager as well and I have added the uploader, panel and the postback trigger button to in an attempt to make it work. Not sure if this will make a difference but the uploader is also not uploading to the TargetFolder.
Here is the requestStart function to cause the postback (I do have the ClientEvents OnRequestStart in the ajaxManager):
Here is the html for the radasyncupload and the postbacktrigger button:
