PivotGridControl.CollapseAllColumnsAsync() Method

Collapses all columns asynchronously.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v20.1.dll

Declaration

public void CollapseAllColumnsAsync()
Public Sub CollapseAllColumnsAsync

Remarks

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.

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

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).
