The GridLookup editor allows end-users to select values from a dropdown grid containing lookup items. GridView is seamlessly embedded into the editor's dropdown window, providing powerful and customizable
data-processing/data-representation options for your lookups (such as sorting, grouping, multi-selection, filtering, templates, and more).
GridLookup is realized by the GridLookupExtension class. Its instance can be accessed via the ExtensionsFactory.GridLookup helper method, which is used to add the GridLookup extension to a View. This method's parameter provides access to the GridLookup's settings implemented by the GridLookupSettings class, allowing you to fully customize the extension.
