Why AsyncFileUpload calls event associated to a LinkButton ?

Hi All,

I have in a TabContainer with one AsyncFileUpload control and one LinkButton with an event OnClick.

When the LinkButton is clicked, its handler download the  previously uploaded file via the AsyncFileUpload control.

But if after downloading the file, the AsyncFileUpload Control is used again, this called the event associated with the LinkButton.

I do not know why this is occurring.  Therefore, any help will be greatly appreciated.

All the best.
