PivotGridControl.CollapseAllAsync() Method

Collapses all columns and rows in PivotGridControl asynchronously.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v22.1.dll


public Task<bool> CollapseAllAsync()


Type Description

An asynchronous operation that returns true in case of success.


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.

If you need to perform specific actions after this operation is completed, use another overload of the CollapseAllAsync method that takes the asyncCompleted parameter, and pass a delegate that performs the required actions as this parameter.

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.
