NuGet Package: DevExpress.Wpf.PivotGrid
Declaration
Returns
| Type | Description |
|---|---|
| Task<Boolean> | An asynchronous operation that returns true in case of success. |
Remarks
The ExpandAllRowsAsync 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 ExpandAllRowsAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.
To expand all rows synchronously, use the PivotGridControl.ExpandAllRows method.
To collapse all rows, use the PivotGridControl.CollapseAllRowsAsync (asynchronous) or PivotGridControl.CollapseAllRows (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).
