Excuse me if this post somewhat overlaps others I've made recently but I've been reviewing your docs and demos concerning RadAsyncUpload and I am getting more confused by the second.
What I need is the following scenario.
1. A single file is selected with the RadAsyncUpload control. (Usual display of file name with remove option)
2. The page goes through several postbacks involving failed validation of other controls while the RadAsyncUpload control retains its display of file name and the option to remove. (It appears that currently this process wipes the display of the RadAsyncUpload control. This was not a problem as long as all validation was client-side. Is there anyway to retain or restore the visible settings of the RadAsyncUpload control, or do I have to write my own code to keep track of the uploaded file?)
3. Once the final postback process occurs the uploaded file is streamed into a database field using an Uploaded File object. (UploadedFile file = RadUpload1.UploadedFiles; file.InputStream.Read etc...)
I recently replaced the old RadUpload controls with RadAsyncUpload controls so I recognize that I may have plugged them into a scenario that no longer works.
(Furthermore I'd like to say that the behavior of the RadAsyncUpload control with regard to the TargetFolder confuses me as well. What happens if two people upload files with identical names at the same time?)
