[Solved] WPF binding to custom class with observable collection

Question

It sounds like you haven’t assigned your DataContext. Below is a brief example.

Assuming your custom class looks something like this:

CODE:

public class Foo
    {
         private ObservableCollection<string> _names;
         public ObservableCollection<string> Names 
         { 
             get{ return _names;} 
             set
             { 
                  _names = value;

             } 
         }
    }

and your XAML looks like

XAML:

<ListBox Name="lstNames" ItemsSource="{Binding Names}"/>

Set your DataContext in code behind.

lstNames.DataContext = new Foo();

This is a very simplistic version to achieve what you need. You should really have a look at Binding to Collections.
