#Remarks
The CollapseAllRowsAsync method is asynchronous. It starts executing the related operation in a background thread, and immediately returns control. The primary UI thread is not blocked, allowing the application to continue responding to end-user actions. For more information about the asynchronous mode, see Asynchronous Mode.
To collapse all rows synchronously, use the PivotGridControl.CollapseAllRows method.
To expand all rows, use the PivotGridControl.ExpandAllRowsAsync (asynchronous) or PivotGridControl.ExpandAllRows (synchronous) method.
To expand or collapse all columns asynchronously, use the PivotGridControl.ExpandAllColumnsAsync and PivotGridControl.CollapseAllColumnsAsync methods, respectively (or the PivotGridControl.ExpandAllColumns and PivotGridControl.CollapseAllColumns methods to do this synchronously).
