If 0 is specified, the running stat will be calculated for all the groups in the grid. If 1 is specified, the running stat will be calculated for all groups of level 1. In otherwords, all the level 1 groups beneath the parent level 0 group. Keep in mind that the value of the running statistical function will be the accumulation of the values found before the current SummaryCell/Row.
If the RunningStatGroupLevel property is assigned a value that is greater than its parent group's level, the result will be the same as if the RunningStatGroupLevel property was set to -1; no running stat.
If a SummaryCell/Row is contained in a detail grid or one of its child groups, its running stat will be contained within the scope of the detail grid. This means that a SummaryCell/Row cannot calculate a running statistical function across multiple (run-time) detail grids.
