    copied!<p>Yeap, approach to solve this problem using IValueConverter is correct and I often use it. But in your case I propose to use only <strong>declarative approach</strong>, because additional converters are additional abstraction in your solution and to understand this logic other programmer must overlook 2 files: declarative and converter implementation. And the colors, which will be switched, are identified in converter :( but not in declarative part. To avoid this, use Microsoft.Expression.Interactions and System.Windows.Interactivity from Blend SDK. Sample code:</p> <blockquote> <p>&lt; Grid x:Name="LayoutRoot" Background="White"></p> </blockquote> <pre><code> &lt; i:Interaction.Triggers&gt; &lt; c:DataTrigger Binding="{Binding BooleanFlagFromViewModel}" Comparison="Equal" Value="True"&gt; &lt; c:ChangePropertyAction TargetName="LayoutRoot" PropertyName="Background" Value="#345678" /&gt; &lt; /c:DataTrigger&gt; &lt; /i:Interaction.Triggers&gt; &lt; /Grid&gt; </code></pre> <p>Hope it helps! Good luck!</p> <p><strong>Update</strong></p> <p>As I write in comment to AnthonyWJones to avoid of accessing to binding resource by Key, I advice to use TriggerAction.</p> <p>1) TriggerAction code:</p> <blockquote> <p>[ContentProperty("Binding")]</p> <pre><code>public class ApplyBindingToDataGridRowAction : TriggerAction&lt;DataGrid&gt; { protected override void Invoke(object parameter) { DataGridRowEventArgs e = (DataGridRowEventArgs) parameter; e.Row.SetBinding(DataGridRow.BackgroundProperty, Binding); } public Binding Binding { get; set; } } </code></pre> </blockquote> <p>2) Use in XAML:</p> <blockquote> <p>&lt; DataGrid ...></p> <p>&lt; i:Interaction.Triggers></p> <pre><code> &lt; i:EventTrigger EventName="LoadingRow"&gt; &lt; a:ApplyBindingToDataGridRowAction&gt; &lt; Binding Path="Is" Converter="{StaticResource Highlighter}"/&gt; &lt; /a:ApplyBindingToDataGridRowAction&gt; &lt; /i:EventTrigger&gt; &lt; /i:Interaction.Triggers&gt; </code></pre> <p>&lt; /DataGrid></p> </blockquote>
