XAML:

    
        
            
                
                    Show/Hide
                
            
        
    

Method:

private void ChangeText(object sender, RoutedEventArgs e)
{
    DemoModel model = (sender as Button).DataContext as DemoModel;
    model.DynamicText = (new Random().Next(0, 100).ToString());
}

Class:

class DemoModel : INotifyPropertyChanged
{
    protected String _text;
    public String Text
    {
        get { return _text; }
        set { _text = value; RaisePropertyChanged("Text"); }
    }

    protected String _dynamicText;
    public String DynamicText
    {
        get { return _dynamicText; }
        set { _dynamicText = value; RaisePropertyChanged("DynamicText"); }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    public void RaisePropertyChanged(String propertyName)
    {
        PropertyChangedEventHandler temp = PropertyChanged;
        if (temp != null)
        {
            temp(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

Initialization Code:

ObservableCollection models = new ObservableCollection();
models.Add(new DemoModel() { Text = "Some Text #1." });
models.Add(new DemoModel() { Text = "Some Text #2." });
models.Add(new DemoModel() { Text = "Some Text #3." });
models.Add(new DemoModel() { Text = "Some Text #4." });
models.Add(new DemoModel() { Text = "Some Text #5." });
DataGrid1.ItemsSource = models;
