	Name	Description
	IncludeNullValues	Gets or sets a value indicating whether a null reference (Nothing in Visual Basic) and DbNull values are included in the count.
	ResultPropertyName	Gets or sets the unique, case-sensitive property name from which the result of the function can be retrieved. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction)
	SourcePropertyName	Gets or sets the name of the column whose values will be used to calculate the result. (Inherited from CumulativeStatFunction)

	Name	Description
	IsInitialized	Gets a value indicating whether Initialize method has been called, indicating that the types in which the values will be accumulated have been initialized. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction)
	IsSealed	Gets a value indicating whether this instance is in an immutable state. (Inherited from CumulativeStatFunction)
	PrerequisiteFunctions	Gets a list of the statistical functions whose results are required by the current statistical function in order to calculate its own result. (Inherited from CumulativeStatFunction)
	RequiresAccumulation	Gets a value indicating whether the statistical function needs to accumulate its own results. (Inherited from CumulativeStatFunction)

	Name	Description
	Accumulate	Overridden. Accumulates the values required to calculate the result of the statistical function. The values will be accumulated in an Int64.
	AccumulateChildResult	Overridden. Accumulates the values required to calculate the result of the statistical function from the results of a child group. The values will be accumulated in an Int64.
	CheckSealed	Checks whether this object is read-only and cannot be changed. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction)
	GetEquivalenceKey	Retrieves a value that represents the statistical function's unique equivalence key (Inherited from CumulativeStatFunction)
	GetResult	Overridden. Retrieves the result of the statistical function.
	Initialize	Initializes the statistical function specifying the types in which the values will be accumulated. (Inherited from CumulativeStatFunction)
	InitializeFromInstance	Overridden. A reference to the StatFunction whose property values will be copied to the current instance of the same-type statistical function.
	InitializePrerequisites	Initializes the prerequisite statistical functions defined by the PrerequisiteFunctions property. (Inherited from CumulativeStatFunction)
	IsEquivalent	Overridden. Retrieves a value indicating whether a statistical function is the equivalent of the current statistical function such that both statistical functions will return the same result for the same set of values.
	Reset	Overridden. Resets the statistical function to its original state.
	Validate	Overridden. Validates the statistical function to ensure that it is able to calculate its result.
