Calling SuspendCalculations will temporarily suspend any automatic calculations performed by the XamCalculationManager until a subsequent call to ResumeCalculations is made.
Note that the suspension refers to automatic calculations only. This means that calculations that would normally be performed on a timer when CalculationFrequency is set to Asynchronous or on a change notification when the value of a control is dirtied when CalculationFrequency is set to Synchronous will not be performed. Explicitly calling the PerformCalculations method or the ICalculationManager's ICalculationManager.EnsureCalculated method will still force a calculation.
Note also that each time SuspendCalculations is called, a counter is incremented. So the same number of ResumeCalculations calls must be made before calculations will resume.
