Notify Property Changed on a Dictionary

Question

I have a WPF / XAML form data-bound to a property in a dictionary, similar to this:

You can just create a class that implement INotifyPropertyChanged interface, wrap your value by this class and use it in Dictionary. I had a similar problem and did next:

class Parameter : INotifyPropertyChanged //wrapper
{
    private string _Value;
    public string Value //real value
    {
        get { return _Value; }
        set { _Value = value; RaisePropertyChanged("Value"); } 
    }

    public Parameter(string value)
    {
        Value = value;
    }

    public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;
    public void RaisePropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

public class ViewModel
{
    public Dictionary Parameters
}

After that, if you change values in the dictionary, you will see the changes in UI.
