Hi,
I design a file upload function,use below this AsyncUpload,RadProgressArea,RadProgressManager in RadAjaxPanel.
When I click one button in RadAjaxPanel, After the page postback, and all of the session value in page will lost.
why? what is the resolution for this?
It's a bit difficult to understand your problem from your description. But, it sounds like you could be facing a time-out if the files are large. Be sure to reference the Asyncupload - Session expired forum thread for some insights.
