<p class="block-content">
<tt>TValueTriggeredCallback</tt> observes the value with <tt>PropertyName</tt> of a
control with <tt>ControlID</tt>. 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.
