Default Eval ImageUrl doesn´t work

Hi guys.

I´m on chapter 7 - Reading Data

and i can´t put the command
<asp:Image ID="Image2" ImageUrl='<%# Eval("PictureURL","~/MatchImages/{0}") %>' runat="server" /> work!

I want to read the name of a file on database and then see the image on the ImageControl.

If i do this:
<asp:Image ID="Image1" ImageUrl="~/MatchImages/aaronson.jpg" runat="server" /> i can see the image

and if i to this:
<asp:DataList ID="DataList1" runat="server" DataKeyField="PictureID" DataSourceID="SqlDataSource1">
            <ItemTemplate>
                <br />
                PictureURL:
                <asp:Label ID="PictureURLLabel" runat="server" Text='<%# Eval("PictureURL") %>'></asp:Label><br />
                <br />
            </ItemTemplate>
        </asp:DataList>
         i can see the name of the image.

Thanks in advance for your help.

Best Regards

I'd like to say I've spotted an error, but no sorry I can't see what the problem is. I compared your code with the grey code block and its explanation below on p242 of the book, and checked the errata.

The problem I had with that exercise is that I could only display one image regardless of the settings of the Repeat... attributes. I found that there was only a single entry in the Gallery table!
