Field Description

Field Name

Target. Binding target is a special type of reference that points to where the evaluation result of binding expression will be written when the binding is processed.

target

Expression. This is an expression that is evaluated every time a binding is processed. The evaluation result is stored in the binding target.

expression

Activator. This is a reference that points to some event or property of the model that will trigger the processing of the binding. The Activator parameter is available only when On event parameter is enabled.

activator

Condition. Condition is an expression that is evaluated first after binding activation. If this expression results to false, the binding execution is skipped.

condition

On Startup. When this parameter is enabled, the binding is processed every time a model instance is created.

onstartup

On Event. When this parameter is enabled and an Activator is specified, the binding is processed whenever there's a changes in the property the activator refers to. If the Activator refers to an event, the binding will be processed when the event fires. If On event is enabled and an Activator is not specified, the binding will be automatically processed: The binding's Expression includes references, pointing to one or more variables. A change in any of these variables will cause the binding to run.

onevent

Periodically. If this parameter is enabled, the binding will be processed periodically.

periodically

Period. Interval between binding processing sessions. This parameter may be changed only if Periodically is turned on.
