    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">
  <!-- Default content -->
</asp:ContentPlaceHolder>

    Page template:

    <asp:Content ContentPlaceHolderID="header" runat="server">
  <!-- Alternate content -->
</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 :)
