Remarks

The CollapseAllAsync 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 expand all columns and rows asynchronously, use the PivotGridControl.ExpandAllAsync method.

To collapse or expand all columns and rows synchronously, use the PivotGridControl.CollapseAll and PivotGridControl.ExpandAll methods, respectively.
