Determining if a RenderSection() was called in Layout page

Question

Is there a way in the Layout to determine if this will render content?

@RenderSection("Right", required: false)

That is determine if there is actually content in the View to place in the section.

Answer 1

Probably not exactly answering your question about testing if the section will render some content but you could test whether a section is defined and render it or provide a default content if this section is not defined:

@if (IsSectionDefined("Right")) { 
    @RenderSection("Right")
}
else { 
    <div>Default content</div>
}
