Class CmsBlock

This data-source delivers the core data for a CMS Block.
It will look up the configuration in the CMS (like the Module-Settings in DNN) to determine what data is needed for the block.
Usually it will then find a reference to a ContentBlock, from which it determines what content-items are assigned.
It could also find that the template specifies a query, in which case it would retrieve that.
Was previously called ModuleDataSource

CmsBlock DataSource (Module-Data)

The CmsBlock DataSource DataSource is part of the Standard 2sxc/Dnn Data Sources. It is the default data source as it directly delivers module-instance data and is used for all scenarios which don't explicitly have a query, and it can also be used as part of a query.

How to use with the VisualQuery

When using the VisualQuery it is already in the default / initial query:

The above example shows:

  1. all data start in the cache ICache
  2. it is then by default passed through the PublishingFilter
  3. then it enters this Instance/Module, which gets the current ModuleInstance and passes on the data which has been assigned to it

Using Module/Instance Data For Configuration

Things get really exciting when you use values which the user edited in the module as a setting in your query. Here's an example:

As you can see, the Default out of the CmsBlock is passed into the ValueSort data source with the stream-name Settings and is then used in a token to configure bbehavior of the sort.

Manually Assigning a Module ID (2sxc 9.9)

In 2sxc 9.9 we added the configuration dialog, so you can specify what module the data should come from. This allows you to have configuration-modules or primary-data-modules, which are re-used in queries:

Programming With The CmsBlock DataSource

We recommend to use the VisualQuery where possible, as it's easier to understand and is identical for C# and JavaScript. It's also better because it separates data-retrieval from visualization.

The only property you need to set is InstanceId (2sxc 9.9+) if you want to provide a different module-id.

History

  1. Introduced in EAV 4.x, 2sxc ?
  2. Added ability to configure in in the visual-query (2sxc 9.9)
