    copied!<p>The concepts covered are INotifyPropertyChanges (in .net 4.5 (minimal changes for other versions but same concept)), ItemsControl and finally style triggers. </p> <h2>INotifyPropertyChanges</h2> <p>My first step is to put INotifyPropertyChanges on our mainwindow to notify the WPF controls of any changes automatically. You will convert your bit array to a list and simply drop it in (maybe on a timer?) when needed. Note it doesn't matter how many there are...the control will expand.</p> <pre><code>public partial class MainWindow : Window, INotifyPropertyChanged { private List&lt;bool&gt; _LedStates; public List&lt;bool&gt; LedStates { get { return _LedStates; } set { _LedStates = value; NotifyPropertyChanged(); } } public MainWindow() { InitializeComponent(); DataContext = this; LedStates = new List&lt;bool&gt;() {true, false, true}; } #region INotifyPropertyChanged /// &lt;summary&gt; /// Event raised when a property changes. /// &lt;/summary&gt; public event PropertyChangedEventHandler PropertyChanged; /// &lt;summary&gt; /// Raises the PropertyChanged event. /// &lt;/summary&gt; /// &lt;param name="propertyName"&gt;The name of the property that has changed.&lt;/param&gt; protected virtual void NotifyPropertyChanged( [CallerMemberName] String propertyName = "" ) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler( this, new PropertyChangedEventArgs( propertyName ) ); } } #endregion } </code></pre> <h2>ItemsControl &amp; Style Triggers</h2> <p>Then in the WPF xaml we will bind to the list of bools and use an item template (think a generic mini view for each data item found). Within that template we will show a color of red or green depending on the state of the boolean. </p> <p>No converter needed because we setup a style trigger which is attune to a target value. If the Textblocks text is "True" we will show Green and when "False" we will trigger/show red.</p> <pre><code>&lt;Window x:Class="WPFBindToArray.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"&gt; &lt;Grid&gt; &lt;ItemsControl x:Name="icBitViewer" ItemsSource="{Binding LedStates}"&gt; &lt;ItemsControl.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;StackPanel HorizontalAlignment="Stretch" IsItemsHost="True" /&gt; &lt;/ItemsPanelTemplate&gt; &lt;/ItemsControl.ItemsPanel&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding}" Grid.Column="0"&gt; &lt;TextBlock.Style&gt; &lt;Style TargetType="{x:Type TextBlock}"&gt; &lt;Style.Triggers&gt; &lt;Trigger Property="Text" Value="True"&gt; &lt;Setter Property="Background" Value="Green" /&gt; &lt;/Trigger&gt; &lt;Trigger Property="Text" Value="False"&gt; &lt;Setter Property="Background" Value="Red" /&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/TextBlock.Style&gt; &lt;/TextBlock&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>When this program is run here is the result:</p> <p><img src="https://i.stack.imgur.com/1C5X5.png" alt="enter image description here"></p>
