I have RadAsyncUpload controls setup on treeview nodes. When multiple files are dragged onto the control, I need to get access to the files on the server side. This works if I wrap the node in an UpdatePanel. However, it causes issues on the rest of my page due to conflicts with other panels.
I can get the event OnClientFilesUploaded to fire and trigger a postback. However, when I try to access the control for that particular node, the uploadedfiles is empty.
