Working with Block Contents

In most cases a template will run in a context - so something prepared data for the template, which should now be visualized. These examples assume you're working with 2sxc, which let's editors work with content - and your template only needs to visualize it. The current content item (if it's just one) is always available on the variable called Content. It's a dynamic object, so you can just type things like @Content.FirstName to access the properties.

The samples can differ based on your Razor base class or if you're running an old version.
Switch to Strong-Typed (2sxc 17.06+) Selected: Typed (2sxc 16+) Switch to Dynamic (Razor14 or below)

Show Entity Values from the current Data

Showing values from Data (aka. Entities) is very easy. Normally they are accessed through Item (new Razor) or DynamicEntity (older Razor) objects.

View Configuration

This is how this view would be configured for this sample.

  • Content/Item ContentType: Persons
  • Content/Item Data:
    1. Douglas (ID: 48832)

Note that Awards refers to other Entities of the type PersonAwards and has properties like Name. The above example showed the award Name using @Content.Awards.Name - which makes sense when you only expect one award. In other tutorials you'll see how to work with such related Entities if there are more than one.

Work with Content Items - MyItem

MyItem is the object which contains the first thing added by the editor on the current block.

Every view/template receives prepared data, usually on the MyItem object.

Douglas Adams on MyItem

Id, Guid and Title are built-in properties

  1. Id: 48832
  2. Guid: 36726e4e-21cd-4c00-9ce8-72080f8935da
  3. Title: Douglas

Use Get(…) if you don't care about the var type...

  1. Name: Douglas
  2. Birthday: 3/11/1952 12:00:00 AM

... or Get<T>(…) which will try to treat as the expected type.

  1. Birthday Get<string> 03/11/1952 00:00:00
  2. Birthday Get<DateTime> 3/11/1952 12:00:00 AM
  3. Birthday Get<bool> False
  4. Birthday Get<int> 0

Use typed methods such as .String(…) if you care about the variable type.

  1. Name (strings): Douglas Adams
  2. Birthday: 3/11/1952
  3. Is Alive: False
  4. Fav Num. Int: 42
  5. Fav Num. Float: 41.99

Use fallback: … to handle empty values or conversion problems.

  1. Name (strings): Douglas
  2. Name (int): 12345

Use .Attribute(…) to safely encode properties. Mouse over this to see the effect.
