The controls in this section provide various ways to display document data from the Kentico CMS database.
Each of these controls inherits a corresponding control from the Basic Listings and viewers section and extends it to easily work with Kentico CMS documents and read and use predefined queries from the system.
The functionality of these controls is very similar to that of the controls in the Standard listings and viewers section, the main difference between them is that these controls use full database queries assigned through their QueryName property to determine the content they display. Only queries stored in the CMS_Query table of the Kentico CMS database can be selected, so if you wish to use a custom query, you must create it there or edit an existing one. The queries can be managed through the administration interface at Site Manager -> Development -> Document types / System tables / Custom tables -> ... Edit () object ... -> Queries.
These controls also support the use of Transformations.
Since the controls in this section use pre-defined queries to read data, certain steps must be taken to keep the functionality of the usual properties that set query clauses, such as OrderBy etc. This must be taken into consideration when writing custom queries. For more information, please refer to the Using control properties to set query clauses topic.
