c# - WPF Event to Command add to control from Codebehind -

i'm using event command explaind here: http://nerobrain.blogspot.nl/2012/01/wpf-events-to-command.html

i try add controls codebehind, since dynamically have add them depending on data db. how perform same thing below codebehind

how add "local" part in codebehind?

update:

this problem i'm trying solve, i'll try summerizes shortly :)

the user supposed leave feedback after usage of application.
feedback information can consist of multiple questions can either

• single choice
• multiple choice.

so 1 feedbackset can have several feedbackgroups can either have single choice feedbackcodes or multiple choice feedbackcodes or have subgroups of feedbackgroups/feedbackcodes

• a single choice result in combobox
• a multiple choice result in listbox
• a subgroup generate treeview

the model(shortend code):

public class feedbackset {     public int id{get;set;}     public string name{get;set}     public list<feedbackgroup> groups{get;set;} }      public class feedbackgroup {     public int id{get;set;}     public string name{get;set;}     public feedbackgrouptype type     public list<feedbackgroup> groups{get;set;}     public list<feedbackcode> codes{get;set;} }  public class feedbackcode {     public int id{get;set;}     public string name{get;set} }  public enum feedbackgrouptype {     subgroup,      single_choice,     multi_choice }      

so can different number , types of controls, based on feedbackset consist of. want id of each selected feedbackcode, i'm trying bind selecteditem event on different controls bind same command.
damn it's hard explain :)

you can implements own custom controls add "local" part mentioned in xaml code.

then create new instances of these controls instead of default ones code behind.
