Hi Dave,
If you wan to put the Build menthod in a seperate class file, Before you call it, you need to declare your PageBuild:
Like below:
PageBuild buider = new PageBuild();
base.AddContentTemplate("ContentPlaceHolder" + i.ToString(), new CompiledTemplateBuilder(new BuildTemplateMethod(buider.Build)));
Hope it helps.
Please remember to mark the replies as answers if they help and unmark them if they provide no help.
Yours sincerely,
