Remarks

CancelPendingOperation method is called to cancel a pending operation. It's only valid for operations that are still pending, that is their Infragistics.OperationResult.IsComplete is false.

An example of how this method is used is as follows. GetActivities method returns ActivityQueryResult object. The activities can be retrieved asynchronously. Before the activities are retrieved, there may be a need for canceling the operation. For example, the user scrolls the schedule control to a different range of dates in which case it's not necessary to retrieve activities for the perviously visible date range. In such a case, the previous query operation will be canceled if it's still pending.
