ASP.Net Ajax AsyncFileUpload control not firing server side OnUploadCompleted event

Question

Hi,

I am writing an application that requires a user to upload files to the server machine. All user interaction with the user is done via JQuery UI modal popups. I created a test page to see that the AsyncFileUpload control works, and everything works fine on it. I added the AsyncFileUpload to the webform that I need it on, in a modal popup, but for some reason the server side event is never fired. The only difference on this page from the test page is that I send a variable through on the querystring which I, on initial load of the page, store in the viewstate (so it isn't required on future postbacks). Any ideas?

Thanks

Answer 1

Did you find any solution regarding your problem?

I got the same issue with ajax toolkit modalpopup and asyncfileupload, it doesn't trigger the event and I get "unknown server error", and I cannot trace it in any way...

When dealing with AsyncFileUpload Control's Event, store any data in Session state instead of viewstate.
