How do I go about providing localised text for items in a custom web control? I had thought that I just need to add meta.resourcekey tags to the control items and then define and fill some resource files called mycontrol.ascx.[lang].resx but that doesn't seem to work.
e.g.
MyControl.ascx
<asp:Label ID="Label1" meta:resourcekey="Label1" runat="server" Text="Oops!"></asp:Label>
MyControl.ascx.de.resx
Label1.Text Donner und Blitzen!
