PHP Class Prado\Web\UI\ActiveControls\TValueTriggeredCallback

Observes the value with {@link setPropertyName PropertyName} of a control with {@link setControlID ControlID}. Changes to the observed property value will trigger a new callback request. The property value is checked for changes every{@link setInterval Interval} seconds. A {@link setDecayRate DecayRate} can be set to increase the polling interval linearly if no changes are observed. Once a change is observed, the polling interval is reset to the original value.

Since: 3.1
