Specifies the identifier of the View for which the View Controller is activated, or a semicolon-separated list of identifiers if a View Controller targets multiple Views.
A string value that is a View identifier or a semicolon-separated list of View identifiers.
By default, the TargetViewId property is set to "Any" (the ActionBase.AnyCaption constant value) which means that the View Controller is activated for any View. You can specify the identifier of a View to enable View Controller activation for a specific View. You can also specify multiple target Views by separating their identifiers by a semicolon (;). The Controller will be activated for each listed View. The TargetViewId value is passed to the Application Model's IModelViewController.TargetViewId property.
