Resource Localization
• The .NET Way
– *.resx
– *.de.resx

Resource Localization
• The ASP.NET Web Forms Way
– [Page/Control].GetGlobalResourceObject(…)
– [Page/Control].GetLocalResourceObject(…)
– <asp:Button ID="btnSubmit" runat="server"
Text="<%$ Resources:btnSubmit.Text %>" />
– <asp:Button ID="btnSubmit" runat="server"
meta:resourcekey="btnSubmit" />
