is this AJAX? If so, you will not be able to update controls on the client
side using server side script in this manner.

the label and button were embedded in edit template cause this error
 
Thanks Gregory.

How should i disable the button to avoid further upload action

Add a JavaScript routine to the button after it is clicked and then enable
it again after upload is completed.
