How to get MVC to ignore undefined sections?

In ASP.NET MVC 3 if you define a section in a view that isn't defined in the layout you get an exception thrown. Is there a way mark the section option from the view ?

You can't render a section in a view that is not defined in the layout.

You can assume like layout is an abstract class and view is a concrete implementation. The section defined in layouts are nothing but abstract methods that will be implemented in views.

So adding a section in view that is not defined in layout is kind of implementing an abstract method that even not exists. And if you define a section in a view it is like adding an abstract method to a concrete class and that changes the view into a layout. Hope this answers your question.

@RenderSection("SomeSection", false)
@if (!IsSectionDefined("SomeSection")) { }

The second part is not necessary, but if you want to do sometheing by default if it is not available.

Sure, there is an overload for RenderSection method that takes second parameter which defines whether the section is required:

@RenderSection("javascript", false)
