我公开了一个集合,并将其绑定到autocompletebox的itemsource,但是在自动完成框中选择或更改文本不会像文本框或标签一样更新模型!

视图模型:

public ObservableCollection<String> SymptomsDb { get; private set; }

private String symptom;

public String Symptom
{
    get { return symptom; }
    set
    {
        symptom = value;
        RaisePropertyChanged(() => this.Symptom);
    }
}

public AnalysisViewModel()
{
    List<String> s = new List<String>();
    s.Add("test");
    SymptomsDb = new ObservableCollection<String>(s);
}

视图:

<controls:AutoCompleteBox 
    ItemsSource="{Binding SymptomsDb}" 
    SelectedItem="{Binding Symptom}" 
    Text="{Binding Symptom}" 
    IsTextCompletionEnabled="True" 
    FilterMode="Contains"/>
