TValueTriggeredCallback Class Observes the value with PropertyName of a control with ControlID. Changes to the observed property value will trigger a new callback request. The property value is checked for changes everyInterval seconds. A DecayRate can be set to increase the polling interval linearly if no changes are observed. Once a change is observe, the polling interval is reset to the original value. Since: 3.1 Author: Wei Zhuo <weizhuo[at]gmail[dot]com>
