Class Paging


The base class for all DataSources, especially custom DataSources. It must always be inherited. It provides a lot of core functionality to get configurations, ensure caching and more.

Important: in most cases you will inherit the CustomDataSource DataSource for custom data sources.

The Paging DataSource is part of the Standard EAV Data Sources. It will limit the items returned to a page containing just a few items, and will also provide a paging-information so that the UI knows what page it's on and how many pages remain.

How to use with the VisualQuery

When using the VisualQuery you can just drag it into your query. This is what it usually looks like:

The above example shows:

  1. a content-type filter limiting the items to type Company
  2. a Paging which only passes on the first 3 companies of page 1

Using Url Parameters for Paging

This example shows how you can use the Url Parameter to page through the results: could also set the page size from other tokens like url or app-configuration, like this:

Programming With The Paging 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.
