Changes to the observed property value will trigger a new callback request. The property value is checked for changes every <tt>Interval</tt> seconds. A <tt>DecayRate</tt> 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. </p> <com:RunBar PagePath="ActiveControls.Samples.TValueTriggeredCallback.Home" /> </com:TContent>
