    copied!<p>I have a <code>ListBox</code> control bound to an <code>ObservableCollection&lt;ToDoCategory&gt;</code> as <code>ItemsSource="{Binding Categories}</code>. Inside the <code>ToDoCategory</code> there are <code>CategoryName</code> and <code>CategoryColor</code> (both strings). <code>CategoryName</code> is bound inside the <code>ItemTemplate</code>. Now, what I would like to do is to change the color of category selected in the <code>ListBox</code> based on <code>CategoryColor</code>. I already have string to brush <code>IValueConverter</code> which returns <code>SolidColorBrush</code> for string. It is also correctly defined in the page resources. I know I need to change <code>ItemContainerStyle</code>. Currently, I have something like this:</p> <pre><code>&lt;Style x:Key="CategoryListBoxContainerStyle" TargetType="ListBoxItem"&gt; Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="ListBoxItem"&gt; &lt;Border...&gt; &lt;VisualStateManager.VisualStateGroups&gt; &lt;VisualState x:Name="Selected"&gt; &lt;Storyboard&gt; &lt;ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="InnerGrid"&gt; &lt;DiscreteObjectKeyFrame KeyTime="0" Value="{Binding CategoryColor, Converter=StringToBrushConverter}"/&gt; &lt;/ObjectAnimationUsingKeyFrames&gt; &lt;ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter"&gt; &lt;DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ListBoxItemSelectedForegroundThemeBrush}"/&gt; &lt;/ObjectAnimationUsingKeyFrames&gt; &lt;/Storyboard&gt; &lt;/VisualState&gt; . . . &lt;/style&gt; </code></pre> <p>This doesn't work. How do I bind the Background of the InnerGrid to <code>CategoryColor</code> from the <code>ToDoCategory</code>?</p>
