copied!<p>Ioana, I don't seem to get what you're aiming at..<br> if you take this xaml:</p> <pre><code><Window x:Class="WpfApplication4.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <TextBox Text="{Binding Path=SelectedText, Mode=TwoWay}" Width="200"/> <ComboBox Width="200" VerticalAlignment="Center" HorizontalAlignment="Center" SelectedItem="{Binding Path=SelectedText, Mode=TwoWay}" ItemsSource="{Binding Path=Texts, Mode=OneWay}"> </ComboBox> </StackPanel> </Window> </code></pre> <p>and this codebehind:</p> <pre><code> public partial class Window1 : INotifyPropertyChanged { public Window1() { InitializeComponent(); this.Texts = new List<string>(new[] {"foo","bar"}); this.DataContext = this; } private ObservableCollection<string> texts; public ObservableCollection<string> Texts { get { return texts; } set { texts = value; if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs("Texts")); } } private string selectedText; public string SelectedText { get { return selectedText; } set { selectedText = value; if (this.PropertyChanged != null) this.PropertyChanged(this, new PropertyChangedEventArgs("SelectedText")); } } public event PropertyChangedEventHandler PropertyChanged; } </code></pre> <p>You do have the Items and the selectedValue databound.<br> Notice the <em>INotifyPropertyChanged</em>.<br> Is this what you're trying to achieve ?</p>
