thanks for the reply. I have looked into the expression builder syntax.
I think its possible to create my own resource expression builder and read from the resource dll.
What I dont like is that when switching the aspx to designer view there is no default text displayed. Is there a way to do this also?
The below line is working well in designer view, since the default text is displayed.
<asp:Label ID="ID_ALERT" runat="server" Text="Alerts" meta:resourcekey="res_NAVI_ALERTS"></asp:Label>
