How do I bind data to a ComboBox?

How to bind custom object data to a ComboBox

• I have a custom class Contact. I am trying to bind a List<Contact> to a ComboBox. But I can't get the right syntax/commands for the Windows.Resources part, e.g. the code below gives the error "The type reference cannot find a public type named 'List'", what do I need to fix in Windows.Resources to get this to work? My XAML: <Window.Resources> <ObjectDataProvider x:Key="contacts" MethodName="GetContacts" ObjectType="{x:Type system:List}"> <ObjectDataProvider.MethodParameters> <x:Type TypeName="local:GetContacts"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider> </Window.Resources> <StackPanel> <StackPanel> <TextBlock Text="Select the contact:"/> <ComboBox ItemsSource="{Binding Source={StaticResource contacts}}"/> </StackPanel> </StackPanel> </Window> My code behind class: namespace dpwpf { class StoreDB { private string connectionString = "App_Data/main.sqlite"; public List<Contact> GetContacts() { SQLiteConnection conn = new SQLiteConnection("Data Source=" + connectionString); SQLiteCommand cmd = conn.CreateCommand(); List<Contact> contacts = new List<Contact>(); try { conn.Open(); cmd.CommandText = String.Format("SELECT * FROM contacts"); SQLiteDataReader reader = cmd.ExecuteReader(); while (reader.Read()) { Contact contact = new Contact( Int32.Parse(reader[0].ToString()), reader[1].ToString(), reader[2].ToString() ); contacts.Add(contact); } } finally { conn.Close(); } return contacts; } } }

• Answer:

  your problem is in this line ObjectType="{x:Type system:List}" this needs to be the object in which GetContacts is defined. if its in youe window1.xaml.cs it would looks something like this ObjectType="{x:Type X:Window1}" HTH Eric,
