WPF C＃Custom UserControl如何添加接受绑定的属性

Question

I'm trying to design a CustomUserControl which consits of an TextEditor and a PopUp...

So the Popup control should be binded to a list... I called it BindingList. This Property should accept any types like ObservableCollection, List, Ienumerable for example(Collections)...

<my:CustomControl BindingList="{Binding Path=Collection}"


 public IEnumerable<object> BindingList
    {
        get { return (IEnumerable<object>)GetValue(BindingListProp); }
        set { SetValue(BindingListProp, value); }
    }

The BindinglistProp

 public static readonly DependencyProperty BindingListProp = DependencyProperty.Register(??????

I have no clue how it should look like that it can accept a binding.

And how should i deal with the Collection which is passed? when it is of a type which i don`t know

like

    class Person
    {
        private string _Name;
        private string _forename;


        public string Name
        {
            get { return _Name; }
            set
            {
                _Name = value;
            }
        }

        public string Forename
        {
            get { return _forename; }
            set
            {
                _forename = value;
            }
        }
    }

Thanks for any hints, tutorials or code snippets.

Answer 1

public IObservable<object> BindingList
{
  get { return (IObservable<object>)base.GetValue(BindingListProperty); }
  set { base.SetValue(BindingListProperty, value); }
}

public static DependencyProperty BindingListProperty =
  DependencyProperty.Register(
  "BindingList",
  typeof(IObservable<object>),
  typeof(CustomControl),
  new PropertyMetadata(null));

查看CollectionViewSource.GetDefaultView以常用方式处理任何集合。
