RadAsyncUpload isnt being consistent with the uploaded files. Attimes, it attempts to upload files that were uploaded in a previous upload, and attimes, it uploads the same file 2ce. I'm not sure what I causing the weird behaviour, but I need some help on this. Any suggestions?
It seems like when an upload is complete, the files uploaded are still being stored in the control somehow, so when a user tries to do a new upload, the files previously uploaded attempt to be uploaded again. What do I need to do to clear out already uploded files. I have ensured that the uploaded temporary files in the RadUploadtemp folder are cleaned out.
Thanks,
Akin

Hi Akinola,
Are you using RadAjaxManager or an UpdatePanel in the page where this behavior occurs. In either case, could you send a simplified page that reproduces the issue, so that we can investigate it locally in order to pinpoint the reason for this behavior.

Hi,
at the risk of sounding impolite, I'd like to ask a quick question, which I think is related to the problem:
Setup:
aspx page
- updatePanel
-- checkbox AutoPostBack
-- submit button (asp.net)
-- RadAsyncUpload (1 file limit, no targetFolder configured, _FileUploaded handler implemented to save file )
Scenario:
- select and upload file in RadAsyncUpload
- checkbox (checked)
-- postback fired
---_FileUploaded processed <-[problem 1]
---UpdatePanel refreshed - RadAsyncUpload is reset <- [problem 2]
-submit clicked
---_FileUploaded fires again tries to move file from temp to target, file not found ......<- [problem 3, result of 1 and 2]
Problem: checkbox triggered submit, not the submit button, causing resets and file issues with AsyncUpload
Question: Is it possible to use RadAsyncUpload inside UpdatePanel while other controls can cause page postback (without loosing state and preventing firing _FileUploaded on each partial postback?
Thank you.
EDIT: FOUND ANSWER - using PostBackTriggers setting for RadAsyncUpload
http://www.telerik.com/help/aspnet-ajax/asyncupload-persist-uploaded-files.html
if PostBackTriggers setting is not congured, then _FileUploaded fires on EVER postback triggered from UpdatePanel controls.
But if you specify at least 1 "true submit" form control in PostBackTriggers, the _FileUploaded fired only for that control.
