Gets the index of the row within a set of alternating rows.
Assembly: PresentationFramework (in PresentationFramework.dll)
Alternating rows are rows to which you can assign different characteristics, such as alternating background colors. You can set the AlternationCount property of the DataGrid to indicate the number of rows within a set of alternating rows. For more information about alternating rows, see ItemsControl.AlternationCount.
Override the OnPropertyChanged method to respond to changes to the property. The property does not have its own property changed method because the AlternationIndexProperty field reuses the read-only ItemsControl.AlternationIndexProperty field.
