    • Required to display data
    • Formats each item from the datasource
  • HeaderTemplate
    • Formats the content before the items from the dataSource
  • FooterTemplate
    • Formats the content after the items from the dataSOurce
  • AlternatingItemTemplate
    • Formats every other item from the dataSource
  • SeperatorTemplate
    • Formats between each item from the dataSource
