Hello - i downloaded the telerik software [licensed software and not trial version] around July 27 2010. While trying to use AsyncUpload i notice that the temporary files are deleted immediately. I found a answer in the forums [http://www.telerik.com/community/forums/aspnet-ajax/async-upload/known-issues-and-breaking-changes.aspx
]. However after implementing the custom handler, i still notice that the temporary files are being deleted. There is an improvement after adding the handler. The firstfile that i upload is not deleted but the second file is deleted immediately before the page post back. Any suggestions on how to prevent the temporary file from being deleted.
