Description

Enumeration of binding expression types to be used by the bindings expressions editor component.

Item	Description
`exprControlToSource`	The bindings expression is unidirectional, binding a property of the control object to a property of the source object. When the control property changes, the source property updates accordingly, but not in reverse.
`exprSourceToControl`	The bindings expression is unidirectional, binding a property of the source object to a property of the control object. When the source property changes, the control property updates accordingly, but not in reverse.
`exprBidirectional`	The bindings expression is bidirectional. Whenever one of the source or control's bound properties changes, the other one is automatically updated.
