Function:

This activity allows a List of DataItems to be created from a list of arbitrary objects. DataItems can be used as input for certain Form elements such as ComboBox items (as a collection of DataItems).

In a Workflow:

Given a list (IEnumerable) of objects of any type, this activity can convert those objects into a list of strongly-typed DataItems, with a value and display name. DataItems can be used as input for certain Form elements such as ComboBox items (as a collection of DataItems). The objects in the list can either have defined values and display name properties, or they can be directly converted to strings with the ToString() method.
