Templates The CollectionView core is based on templates. Each section in the CollectionView consists of a header, footer and a number of items (elements). During creation, these elements are initialized and reused where possible, the CollectionView reads the controls inside the template, creates them and triggers a set of events (explained in the table of public and published events) that can be used to assign a value to a specific control inside an element based on the section and row parameter. For header and footers, the row parameter will always be 0. 131
