PivotFieldImageIndexEventArgs.ChangeExpandedState() Method

Changes the expanded state of the current field value.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v19.1.dll


public void ChangeExpandedState()


If the processed field value is collapsed, calling the ChangeExpandedState method expands this value. Otherwise, if the field value is expanded, the ChangeExpandedState method collapses it.


If you call the ChangeExpandedState method while an asynchronous operation is being performed, an exception will be thrown. To determine whether the operation is in progress, use the pivot grid’s IThreadSafeAccessible.IsAsyncInProgress property. For more information, see Asynchronous Mode.
