The UnboundExpressionEditorCreated event's handler receives an argument of the UnboundExpressionEditorEventArgs type. The following properties provide information specific to this event:

Property	Description
Column	Gets an unbound column whose expression will be edited in the Expression Editor.
ExpressionEditorControl	Gets the Expression Editor.
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.

Remarks

The Expression Editor allows an end-user to edit expressions for unbound columns. The Expression Editor can be invoked using a column's context menu or in code via the DataViewBase.ShowUnboundExpressionEditor method.

The UnboundExpressionEditorCreated event fires after the Expression Editor has been created, before it's displayed onscreen. Handle this event, to prevent the editor from being displayed or customize its settings (UnboundExpressionEditorEventArgs.ExpressionEditorControl).
