關於DevExpress WPF DataGrid 如何根據某列內容來改變整行顏色

<Window x:Class="ConditionalRowFormatting.MainWindow"

    <Window.Resources>
        <ResourceDictionary>
            <local:SimpleDataList x:Key="simpleSource" InitCount="25" />
            <Style x:Key="BackgroundStyle" BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=RowStyle}}" TargetType="{x:Type dxg:GridRowContent}">
　　　　　　　　　　//重點：這里Binding的是 Row.Int 也就是行中哪一列的值.
                <Setter Property="Background" Value="{Binding Path=Row.Int, Converter={local:ColorValueConverter MaxValue=25}}" />
            </Style>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <dxg:GridControl ItemsSource="{StaticResource simpleSource}" AutoGenerateColumns="AddNew">
            <dxg:GridControl.View>
                <dxg:TableView AutoWidth="True" RowStyle="{StaticResource BackgroundStyle}" />
            </dxg:GridControl.View>
        </dxg:GridControl>
    </Grid>
</Window>

值轉換器：

public class ColorValueConverter : MarkupExtension, IValueConverter {
        public int MaxValue { get; set; }
        #region IValueConverter Members
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {
            int count = MaxValue - (int)value;
            return new SolidColorBrush(GetGradientColor(count));
        }
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) {
            return null;
        }
        #endregion
        public override object ProvideValue(IServiceProvider serviceProvider) {
            return this;
        }
        private Color GetGradientColor(int count) {
            Color color = Color.FromRgb(0xff, 0xad, 0x5d);
            byte r = (byte)(color.R + (0xff - color.R) * count / MaxValue);
            byte g = (byte)(color.G + (0xff - color.G) * count / MaxValue);
            byte b = (byte)(color.B + (0xff - color.B) * count / MaxValue);
            return Color.FromArgb(255, r, g, b);
        }
    }
