Asp.net 2.0. Binding a Gridview. UNtil now, it had been simple
BoundColumns, but now I need to have one column show the values of 3
columns ( they are in the same datasource).

I thought that I should just be able to use a template sucha as :

<asp:TemplateField d>
               <HeaderTemplate><asp:Label runat=server>Test</
asp:Label></HeaderTemplate>
               <ItemTemplate>
               <asp:Label runat=server><%Eval("F");%>//<%Eval("M");
%> <%Eval("L"); %></asp:Label>
               </ItemTemplate>
               </asp:TemplateField>

but that didn't work out.

Any suggestions?
