DetailsView and FileUpload

[Andre]

Hi,

In my detailsview, when editing, i try to use a Filepload field to
change the file name in my DB and upload it to the server.
But when i click the Update button i receive this error : Must declare
@image1

Every other field in my detailsview (textbox, checkbox, calendar) are
working #1, but not this one...

Here's a copy of my code :

<asp:TemplateFi eld HeaderText="Ima ge 1">
<EditItemTempla te>
<asp:FileUplo ad ID="FileUpload1 " runat="server" />
</EditItemTemplat e>
<ItemTemplate >
<asp:Image ID="image1" runat="server" ImageUrl='<%# "images/" &
Eval("image1") %>' Width="150" />
</ItemTemplate>
</asp:TemplateFie ld>
Any ideas ?
Thanks
