Setting default content of a section (MVC)
I'm having troubles finding out how to set the default content of a section when working with MVC Views.

I have a master template called _Layout.cshtml, where I have a section called @RenderSection("header",false). In most of my templates, I just want the content to be inherited from the master, but in a few I would like to modify it.

Before working with views I would have done it like this.

Master:
```
<asp:ContentPlaceHolder ID="header" runat="server">
  
</asp:ContentPlaceHolder>
```
Page template:
```
<asp:Content ContentPlaceHolderID="header" runat="server">
  
</asp:Content>  
```
How's that achieved when working with Views?

I think this blog post should explain a solution to your problem. The first solution being to check if a child section has been defined...

  @if (IsSectionDefined("Footer")) {
      RenderSection("Footer");
  }
  else { 
      This is the default yo!   
  }

And the second being a custom helper method which accepts some default content...

public static class Helpers {
  public static HelperResult RenderSection(this WebPageBase webPage, 
      string name, Func defaultContents) {
    if (webPage.IsSectionDefined(name)) {
      return webPage.RenderSection(name);
    }
    return defaultContents(null);
  }
}

  @RenderSection("Footer", @This is the default!)

Thanks!

I don't get the second part, but the first is working, so I'm happy :)
