PivotGridControl.ExpandAllColumnsAsync() Method

Expands all columns asynchronously.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v23.2.dll

NuGet Package: DevExpress.Wpf.PivotGrid


public Task<bool> ExpandAllColumnsAsync()


Type Description

An asynchronous operation that returns true in case of success.


The ExpandAllColumnsAsync 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 ExpandAllColumnsAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.

To expand all columns synchronously, use the PivotGridControl.ExpandAllColumns method.

To collapse all columns, use the PivotGridControl.CollapseAllColumnsAsync (asynchronous) or PivotGridControl.CollapseAllColumns (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).
