Question

i’m a WPF noob .
iv’e got a listbox which is bound to a Property of class Client

public class Client : INotifyPropertyChanged
{
    private List<Player> peers ;
    public List<Player> Peers 
    {
        get { return peers; }
        set
        {
            peers = value;
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs("Peers"));
        }
    }
}

the listbox parent’s datacontext is bound to a Client instance

  GameDetailsPanel.DataContext = client;      

the listbox is bounded as follows :

 <ListBox.Items>
     <Binding Path="Peers"></Binding>
 </ListBox.Items>

to my understanding this is suppose to bound the list to the path relative to it’s parent’s
datacontext .. when i run the application i get the following error:

   {"A 'Binding' cannot be used within a 'ItemCollection' collection. A 'Binding' can only be set on a DependencyProperty of a DependencyObject."}

any ideas what i’m doing wrong .

Answer 1

You need to set the ItemsSource to your List of Players.

 <ListBox ItemsSource="{Binding Peers}">
 </ListBox>
