Page templates and syntax
Layout templates are aspx files with includes and calls to helpers.
Currently, we have only content zones, so a template can look like this:
<html> <head> <link rel="stylesheet" type="text/css" href="<%= ResolveUrl("~/Content/StyleSheet.css") %>" /> </head> <body> <div class="header"> <%= Html.Include("header") %> </div> <div class="centerContentZone"> <%= Html.IncludeZone("Content") %> </div> <div class="rightSidebar"> <%= Html.IncludeZone("Right sidebar") %> </div> <div class="footer"> <%= Html.Include("footer") %> </div> <%= Html.IncludeAdmin() %> </body> </html>
The helpers used above are: Html.Include(string includeName) includes the partial view whose name is specified. Html.IncludeZone(string zoneName) includes a named content zone. * Html.RenderAdmin() includes the admin link if the user is logged in as administrator.
Template meta-data is stored directly in the template file as server comments. They are in a simple key-value format. Keys and values are separated by a colon character:
<%@Page %> <%-- name: Two column layout description: This has a main content area and a sidebar on the right. zones: Content, Right sidebar author: Jon --%>
The keys in the meta-data are case-insensitive.
Meta-data values can be on multiple lines.
The syntax for meta-data is YAML.
The fields that are not recognized are put in a dictionary so that they are still accessible from code.
The last piece of meta-data, which is optional, is the thumbnail representation for it that is used in the template selection screen and in the edit page screen. This is a PNG or GIF image that has the same name as the template file and that is stored in the same directory.
