https://wpftoolkit.codeplex.com/wikipage?title=IntegerUpDown&referringTitle=NumericUpDownボタンカラーIntegerUpDown（拡張WPFツールキット）を変更するには？
私は矢印ボタンの背景色を青に変更しようとしています。
私はそれがSpinnerButtonStyleKeyとは何かを持っていると信じて：
私はセッターでPNG画像を使用して、テキストボックスの背景と前景を変更することができました。
私が使用して矢印の色を変更する方法が見つかりました：ここ
<SolidColorBrush x:Key="{x:Static theme:ResourceKeys.GlyphNormalForegroundKey}" Color="White"/>
は、XAMLのテンプレートです：
<Style x:Key="IntegerUpDownBlue" TargetType="{x:Type wpfTool:IntegerUpDown}">
<Setter Property="Background">
<Setter.Value>
<ImageBrush ImageSource="Resources/Images/TextBoxEnabled.png" Stretch="None" AlignmentX="Left" AlignmentY="Bottom"/>

私は追加して、この部分を変更してみましたSolidColorBrush x：Keyですが、私は何の変化も見ません。
<wpfTool:ButtonSpinner x:Name="PART_Spinner"...
Background="{StaticResource IntegerUpDown.volume.Spinner.Static.Background}"
私はBorderBrushをchaning試してみました：
<Setter Property="BorderBrush" Value="Blue"/>
私もこのソリューションを試みたが、コードはめちゃくちゃと "RepeatButtonを「クロージングXMLタグをエラー" と言う不一致です：
