An instance of the ExpressionsCollectionEditor class is a UITypeEditor object that can be used at design time to select and edit a collection of expression bindings, and assign the expressions to a control property.

A designer host, such as Visual Studio 2005, uses the ExpressionBuilder and ExpressionEditor class implementations with the ExpressionsCollectionEditor and ExpressionsCollectionConverter classes to set the expression bindings for control properties at design time, and the ControlPersister class to persist the expressions for run time. Expression strings reference a localizable resource, an application setting, a connection string, or a custom expression type. The expression string is bound to the control property at design time, and then used at run time to determine the value for the property.
