Clone un GridColumn en conservant les gestionnaires d'événements (ClickEvents) et les propriétés de ses éléments identiques

Question

J'ai une application avec 4 onglets. Dans les trois premiers onglets, j'ai quelques GridColumns remplis d'éléments (Boutons, CheckBoxes, ComboBoxes, Labels etc). Chaque onglet a des éléments différents.

Ce que je veux faire, est de copier/clone uniquement les colonnes choisies dans chaque onglet à l'onglet 4, pour que je puisse avoir une meilleure modification de mes données. Chaque colonne clonée doit avoir la même fonctionnalité que sa "mère".

J'ai réussi à avoir les colonnes que je sélectionne dans mon onglet « fin », mais les éléments de celui-ci ne possèdent pas les mêmes fonctions et eventhandlers que celles d'origine. Comment puis-je faire en sorte que les colonnes clonées soient les mêmes que celles d'origine? Est-ce une bonne façon de cloner les colonnes que j'ai utilisées?

J'ai fait un simple échantillon de ma demande, pour vous montrer son format. J'écris du code en C# et WPF.
