Hello,
I'm trying to streamline an app by converting inline code into a
functions.vb file in the App_Code folder but can't seem to work out
this error: The code worked fine in its "inline version".
BC30456: 'LinkCat_ItemDataBound' is not a member of 'ASP.default_aspx
Line 45: <asp:DataList id="LinkCat" RepeatColumns="2"
RepeatDirection="Horizontal" OnItemDataBound="LinkCat_ItemDataBound"
runat="server">
Many thanks in advance.
