I followed the instructions on the post and succesfully linked the layout template to a blank control with the property CausesValidation set to false.
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Navigation.ascx.cs" Inherits="Modules_Navigation" CausesValidation="false" %>
This results in an error. I need a lot
more specific information. As I said before, I am not experienced.
