Extensions

A datagrid object only takes care of converting datasource to the result set. All other operations are performed by extensions (e.g., pagination, filtering, etc.).

Here is a list of already implemented extensions:

• Formatter - responsible for backend field formatting(e.g., generating URL using router, translation using Symfony translator, etc.). This extension also takes care of passing column configuration to the view layer.
• Pager - responsible for pagination
• Sorter - responsible for sorting
• Action - provides actions configurations for grid
• Mass Action - provides mass actions configurations for grid
• Toolbar - provides toolbar configuration for view
• Grid Views - provides configuration for grid views toolbar
• Export - responsible for export grid data
• Field ACL - allow to protect entity fields with ACL
• Board - responsible for adding Kanban board views for datagrids
• Filter - responsible for adding filtering and filter widgets to grid
• Organization Column - responsible for adding the organization column if a user works in the global organization

Customization

To implement your extension:

• Develop a class that implements ExtensionVisitorInterface (there is also a basic implementation in AbstractExtension class)
• Register you extension as service with tag { name: oro_datagrid.extension }
