Repeater

The Repeater control is a container. You bind the Repeater control to a data source, and the Repeater control shows the items that the data source provides.

The Repeater control is different from other containers (such as the ListControl control) in these ways:

• The Repeater control does not render items.
• You can add and remove controls that show items client-side. This means that SPEAK does not have to reload the page when items are added or removed.

To use the Repeater control you must:

• Create a template in the core database for the items you want the Repeater control to display.
• Open the Design Layout of the _Standard Values of the template you created and add renderings to this layout.
• Create items based on this template in the core database. (You can use the Item Web API or Sitecore.Services.Client to create items if you need to do this programmatically.)
• Add a data source component to your page. This data source component must return the items you created.
• Bind the Items property of the Repeater control to the data source.

The Repeater control displays the items with the renderings you added to _Standard Values.

The Repeater control itself does not provide logic for adding and removing items, but you can add this functionality in page code.
