Thank preishuber.

Finnally, I use Foreground Binding a property in my dataclass

In my data class, add ForeColor

    public class MyData : INotifyPropertyChanged
    {
        #region Static Brush

        private static Brush _highPriceBrush;
        public static Brush HighPriceBrush
        {
            get
            {
                if (null == _highPriceBrush)
                    _highPriceBrush = new SolidColorBrush(Colors.Red);
                return _highPriceBrush;
            }
            set { _highPriceBrush = value; }
        }

        private static Brush _lowPriceBrush;
        public static Brush LowPriceBrush
        {
            get
            {
                if (null == _lowPriceBrush)
                    _lowPriceBrush = new SolidColorBrush(Colors.Blue);
                return _lowPriceBrush;
            }
            set { _lowPriceBrush = value; }
        }

        #endregion

        private float _price;
        public float Price
        {
            get { return _price; }
            set
            {
                _price = value;
                PropertyChanged(this, new PropertyChangedEventArgs("Price"));
                PropertyChanged(this, new PropertyChangedEventArgs("ForeColor"));
            }
        }

        public Brush ForeColor 
        {
            get
            {
                if (Price > 100.0f)
                    return _highPriceBrush;
                else
                    return _lowPriceBrush;
            }
        }

        #region INotifyPropertyChanged

        public event PropertyChangedEventHandler PropertyChanged;

        #endregion

    }

 in Page.XAML like this:

                    <data:DataGridTemplateColumn Header="Price" IsReadOnly="True">
                        <data:DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Price}" Foreground="{Binding ForeColor}" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,5,0"/>
                            </DataTemplate>
                        </data:DataGridTemplateColumn.CellTemplate>
                    </data:DataGridTemplateColumn>

 

It works, but I think it is not a best way.
