The field value currently being processed.
If the currently processed header is a field value or total header the Value property returns the value of the corresponding column field or row field. If the currently processed header is a grand total header or data field header the Value property will return null.
To determine the type of the currently processed header, use the PivotFieldImageIndexEventArgs.ValueType property.
If you try to access the Value property 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.
