Occurs after a cell's editor has been closed.

Public Event HiddenEditor As EditorEventHandler
The HiddenEditor event handler receives an argument of the DevExpress.UI.Xaml.Grid.EditorEventArgs type.
When an end-user activates a cell within a column with a custom template, the GridControlBase.ShownEditor event is not raised. Since the HiddenEditor event is not raised either, the DataControlBase.ActiveEditor property value always stays null.
