Hi,
The trick is to force the file upload control to perform a full postback , and we do this using triggers . Triggers allow the developer to specify what will cause partial and full postbacks. They must be defined within the UpdatePanel but outside of the ContentTemplate . We want to create a trigger that will instruct the linkButton that you are using for the upload to perform a full postback.
Triggers > asp : PostBackTrigger ControlID ="LinkButton1" />
