When developing pages for Microsoft Dynamics NAV Tablet client that include a repeater control, it is useful to be able to define whether the actions available on a page apply to the whole page or are related to the repeater control on the page. The purpose of the Scope property is to enable application developers to add row-specific actions to the shortcut menu which is available to the user on each line. This gives users a more direct way to invoke actions that relate to the selected row/line.
This is the case when you have, for example, Line Comments which are related to a line, but appear in the ribbon. You can specify the scope of action by setting the Scope property on the page action to be either Page or Repeater.
