How can I set a variable on a _Layout page?

Question

I have a view and I want to use a layout page. In the layout page I want to have a conditional banner which some of the view will turn on/off. Just wondering how I can do this?<

Answer 1

Having a model for your layout is not a good idea as it will force all views to use that model. However, you could put that type of information into the ViewBag and have the value populated in the constructor of one of your controller bases.
