ReCalc() Method

Forces recalculation of all dirtied items in the Calcultion Network.
Syntax
'Declaration
 
Public Overloads Function ReCalc() As Boolean
public bool ReCalc()

Return Value

Returns a boolean indicating if anything in the Calculation Network is dirty. This should always return false.
Remarks

The ReCalc method forces the synchronous recalculation of all formulas in the calculation network.

When the CalcFrequency property is set to Manual, no calculations are performed unless this method or the Infragistics.Win.CalcEngine.IUltraCalcManager.EnsureCalculated(Infragistics.Win.CalcEngine.IUltraCalcReference,System.Boolean) method is called.

When the CalcFrequency property is set to Asynchronous, this method can be called to force all calculations to be completed synchronously, so that calculated values can be depended upon to be correct. It is generally more efficient to use the Infragistics.Win.CalcEngine.IUltraCalcManager.EnsureCalculated(Infragistics.Win.CalcEngine.IUltraCalcReference,System.Boolean) method in this case, since it ensures the calculation of a single reference as opposed to all references in the calculation network.

When the CalcFrequency property is set to Synchronous, this method is usually not neccessary, unless a control in the calculation network that is being used as the source of a calcatulion does not have a event for the property being used as its PropertyName In this case, it is generally more efficient to use Infragistics.Win.CalcEngine.IUltraCalcManager.EnsureCalculated(Infragistics.Win.CalcEngine.IUltraCalcReference,System.Boolean) instead of ReCalc.

Example
UltraCalcManager by default does calculations asynchronously using a timer. You can use ReCalc method to force UltraCalcManager to perform calculations.
