A AsyncCompletedHandler delegate referencing a method that should be executed after the operation is completed.


The CollapseAllColumnsAsync 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 columns synchronously, use the PivotGridControl.CollapseAllColumns method.

To expand all columns, use the PivotGridControl.ExpandAllColumnsAsync (asynchronous) or PivotGridControl.ExpandAllColumns (synchronous) method.

To expand or collapse all rows asynchronously, use the PivotGridControl.ExpandAllRowsAsync and PivotGridControl.CollapseAllRowsAsync methods, respectively (or the PivotGridControl.ExpandAllRows and PivotGridControl.CollapseAllRows methods to do this synchronously).
