    FileUpload clears on Insert

    I have a FileUpload control within a FormView (although I tried it outside
    the FormView and got the same result) in the InsertTemplate. When the
    <Insertbutton is clicked and the Insert Command is executed the FileUpload
    is cleared of it's value and hence during Insert there is no file to
    "insert". I even tried this with a separate button that was both inside and
    outside the form view and not connected to the Insert Command, and still the
    FileUpload get's cleared.

    How can I either stop the value from being cleared or what should I do
    differently to accomplish the same result?

      Your button causes a postback and the FileUpload Control lost its
      value. To solve this, you could use the UpdatePanel and wrap that
      around the controls that are causing the postback.

          Actually the FormView is already in an UpdatePanel. Here's the code:

              The FileUpload Control must be out of the UpdatePanel, otherwise it
              will be updated once button is clicked. Or, you have to perfom a file
              upload when you click on the button.

                      I think, his problem is different. His FileUpload Control lost the
                      text value on a postback. It has nothing to do with an UpdatePanel
                      because it's a standard behavior of the FileUpload. It does not keep
                      the value after postback.
