Példák

Az alábbi példa egy ToolBar és három ToolBarButton vezérlőt hoz létre. Az eszköztárgombok a gombgyűjteményhez vannak rendelve, a gyűjtemény az eszköztárhoz van rendelve, és az eszköztár hozzá lesz adva az űrlaphoz. ButtonClick Az eszköztár eseményén a rendszer kiértékeli a ButtonToolBarButtonClickEventArgs tulajdonságot, és megnyílik a megfelelő párbeszédpanel. Ez a kód feltételezi, hogy egyForm, egy OpenFileDialogSaveFileDialogés egy PrintDialog példány lett létrehozva.
