Gets or sets the delay before an automatic data loading operation is started. It is the delay from the time a change prompting automatic load occurs until the time the resulting Load is started. The default delay is 25 milliseconds.
Multiple changes that occur within the specified time span are aggregated into a single Load operation. For every change that occurs, the delay timer is reset. This allows many changes to be combined into a single call as long as each change occurs within the specified delay from the last. Once the delay timer is allowed to elapse without a change occurring, Load will be invoked.
