Binding a WPF ComboBox to a custom list

Question

I have a ComboBox that doesn\'t seem to update the SelectedItem/SelectedValue.

The ComboBox ItemsSource is bound to a property on a ViewModel class that lists a bunch

Answer 1

To bind the data to ComboBox

List ListData = new List();
ListData.Add(new ComboData { Id = "1", Value = "One" });
ListData.Add(new ComboData { Id = "2", Value = "Two" });
ListData.Add(new ComboData { Id = "3", Value = "Three" });
ListData.Add(new ComboData { Id = "4", Value = "Four" });
ListData.Add(new ComboData { Id = "5", Value = "Five" });

cbotest.ItemsSource = ListData;
cbotest.DisplayMemberPath = "Value";
cbotest.SelectedValuePath = "Id";

cbotest.SelectedValue = "2";

ComboData looks like:

public class ComboData
{ 
  public int Id { get; set; } 
  public string Value { get; set; } 
}
