    <p>I have a label control where I use a converter to switch its styles based on a bool property, IsCheckedOut on my viewmodel, like so:</p> <pre><code> &lt;UserControl.Resources&gt; &lt;Converters:BooleanStyleConverter x:Key="BooleanStyleConverter " StyleFalse="{StaticResource HeaderLabelStyle}" StyleTrue="{StaticResource HeaderLabelHighlightedStyle}" /&gt; &lt;/UserControl.Resources&gt; &lt;Label Style="{Binding Path=IsCheckedOut, Converter={StaticResource BooleanStyleConverter}}"&gt; some content here &lt;/Label&gt; </code></pre> <p>The converter simply returns one of the two styles:</p> <pre><code>public class BooleanStyleConverter : IValueConverter { public Style StyleFalse { get; set; } public Style StyleTrue { get; set; } public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if ((bool)value) { return StyleTrue; } return StyleFalse; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } </code></pre> <p>And the styles look something like this:</p> <pre><code>&lt;Style x:Key="HeaderLabelHighlightedStyle" TargetType="{x:Type Label}"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="Label"&gt; &lt;Border Background="{StaticResource RedGradient}"&gt; &lt;ContentPresenter /&gt; &lt;/Border&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; &lt;Style x:Key="HeaderLabelHighlightedStyle" TargetType="{x:Type Label}"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="Label"&gt; &lt;Border Background="{StaticResource BlueGradient}"&gt; &lt;ContentPresenter /&gt; &lt;/Border&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>So when IsCheckedOut is true the label gets a red background, and when it's false it gets a blue background (well, the styles are a bit more complicated, but you get the idea). Now, I'd like to have a transition between the styles, so that the new colors fade in when IsCheckedOut changes. Does anyone know how I can accomplish this? </p>

    1. CODo you really need styles? Because you could use a story board with a color animation to change the background of the label.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
