FileUpload clears on Insert

[=?Utf-8?B?VEQgaXMgUFNQ?=]

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.
