PivotGridControl.CollapseAllRowsAsync() Method
Collapses all rows asynchronously.
Namespace: DevExpress.XtraPivotGrid
Assembly: DevExpress.XtraPivotGrid.v19.1.dll
Declaration
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.
If you need to perform specific actions after this operation is completed, use another overload of the CollapseAllRowsAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.
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).
