Remarks
The Expression Editor allows end-users to edit expressions for unbound fields. It can be invoked as described in PivotGridControl.ShowUnboundExpressionEditor.
The UnboundExpressionEditorCreated event fires after the Expression Editor has been created, and before it is displayed on-screen. You can handle this event to customize the expression editor settings.
Use the PivotUnboundExpressionEditorEventArgs.Field property to obtain the unbound field for which the Expression Editor has been invoked.
