ASP.NET MVC - Render section conditionally in Layout

Question

i have following code in my _Layout.cshtml:

@if (SiteConfig.Instance.HasCustomMarkup)
{
     @RenderSection("bodyPart1", false)
     @RenderBody()
     @RenderSection("bodyPart2", false)
}
else
{
    <div id="mainContainer">
        @RenderBody()
    </div>        
}

So i try to render sections only on some condition. But it is not work and i have an exception:

The following sections have been defined but have not been rendered for the layout page ...

Is there any workaround in mvc for this purposes? thanks!

Simply check whether or not section exists, i.e.:

@if (IsSectionDefined("bodyPart1"))
{
    @RenderSection("bodyPart1")
}
