Upload files on a callback and postback and handle the upload control's FilesUploadComplete event to save the files on the server.
Use the loading panel's client-side functionality to invoke the panel on page load.
Add a description, image, and links to the postback topic page so that developers can more easily learn about it.
To associate your repository with the postback topic, visit your repo's landing page and select "manage topics."
