public abstract class StatFunction
Only the statistical functions that are added to the StatFunctions collection of a DataGridCollectionView or DataGridCollectionViewSource can be used.
The values used to calculate the results of a statistical function are retrieved from its statistical context. For example, if an element that displays the results of a statistical function is contained in a group footer, the element's statistical context will be the group, and the results of the statistical function will be calculated according to the values of the data items in the group. If the same element is placed in the footers of a grid, then its statistical context is provided by a grid (through the StatContext property) and all the data items will be used to calculate the results.
The same statistical function can be used by more than one element, regardless of the statistical context. For example, if the average of a column is to be displayed in both the footers of a group and a grid, only one AverageFunction needs to be added to the StatFunctions collection.
Statistical functions that are calculated for a specific detail-level cannot be accessed by parent, child, or sibling detail-levels nor can they be accessed by a master grid and vice-versa.
With the exception of the CountFuntion, a null reference (Nothing in Visual Basic) and DBNull values will be ignored.
