TabStemが動作していないVisualStateManager.GoToState

Question

私のtabitemは、FlashingというVisualStateを持つResourceDictionaryによってスタイルされています。 私はこのようなことをしたいが、それは働かない。

public static void FlashTab(TabItem tbi) 
{ 
    bool thisReturnsFalse = VisualStateManager.GoToState(tbi, "Flashing", true); 
}

Answer 1

あなたはタブコントロールの親ウィンドウのWindow.ResourcesへのResourceDictionaryをマージするときのTabItemは（ResourceDictionaryのがここResourceDictionary.xamlである）点滅します：

<Window.Resources> 
    <ResourceDictionary> 
     <ResourceDictionary.MergedDictionaries> 
      <ResourceDictionary Source="ResourceDictionary.xaml"/> 
     </ResourceDictionary.MergedDictionaries> 
    </ResourceDictionary> 
</Window.Resources> 

と、GlassCubeの長方形のOpacityMaskを修正したときに発生します。私はそれをコメントアウトし、それは幸せに点滅します：

<Rectangle x:Name="GlassCube" Margin="1,1,1,1" RadiusY="5" RadiusX="5" StrokeThickness="3" Opacity="1"> 
    <Rectangle.Stroke> 
     <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 
      <GradientStop Color="{DynamicResource TabBrush4}"/> 
      <GradientStop Color="{DynamicResource TabBrush4}"/> 
      <GradientStop Color="{DynamicResource TabBrush6}" Offset="0.254"/> 
      <GradientStop Color="{DynamicResource TabBrush5}" Offset="0.401"/> 
     </LinearGradientBrush> 
    </Rectangle.Stroke> 
    <!--<Rectangle.OpacityMask> 
     <RadialGradientBrush> 
      <GradientStop Color="{DynamicResource TabBrush11}" Offset="0"/> 
      <GradientStop Color="{DynamicResource TabBrush13}" Offset="1"/> 
     </RadialGradientBrush> 
    </Rectangle.OpacityMask>--> 
    <Rectangle.Fill> 
     <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 
      <GradientStop Color="{DynamicResource TabBrush12}"/> 
      <GradientStop Color="{DynamicResource TabBrush7}" Offset="0.47"/> 
     </LinearGradientBrush> 
    </Rectangle.Fill> 
</Rectangle> 

EDIT：色のリソースのキーについて言及してもう一つのことがあります。あなたは、キーTabBrush1、TabBrush2などでそれらを定義していますがColor="{DynamicResource ...}"でそれらを使用する場合、あなたは常にあなたのあなたのResourceDictionaryが定義されたスタイル、および任意の詳細情報を表示するために、おそらく良いアイデアをキーBrush1などBrush2
