Question

I am binding a combobox in the WPF using MVVM pattern. I am able to bind a list of string with the combobox but I don’t know how to set a default value in the combobox.
Well I have a list of names which has “A”,”B”,”C” and “D”. Now I want that by default “A” should come as default value.

Thanks

    <ComboBox Height="23" Width="120" ItemsSource="{Binding Names}"/>

public class NameViewModel
{
   private IList<string> _nameList = new List<string>();
   public IList<string> Names { get; set; }
   public NameViewModel()
   {
       Names = GetAllNames();
   }

   private IList<string> GetAllNames()
   {
       IList<string> names = new List<string>();
       names.Add("A");
       names.Add("B");
       names.Add("C");
       names.Add("D");
       return names;
   }
}

I think you should try to use ListItem. ListItem has Selected property
