    <p>I have a ListView with AlternationCount set to 2. I have a ListViewItem style that currently sets the background color of the ListViewItem to alternating colors, and I would like to add a third trigger which triggers a ColorAnimation to animate the color between Red and White when a property of the bound ViewModel is true (in this case a property called "Locked").</p> <p>I came across this post, and tried the xaml at the bottom:</p> <p><a href="http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/e7897cbd-71d9-45e6-9b17-0cd5bde5859f" rel="nofollow">http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/e7897cbd-71d9-45e6-9b17-0cd5bde5859f</a></p> <p>But, the animation doesn't appear to trigger for me until I mouse over or select the item, then select or mouse over a different item. I get the alternating colors from the first two MultiDataTriggers, but the animation doesn't trigger when the item is added to the collection. Here is my XAML:</p> <pre><code> &lt;Style x:Key="alternatingListViewItemStyle" TargetType="{x:Type ListViewItem}"&gt; &lt;Setter Property="Background" Value="White" /&gt; &lt;Style.Triggers&gt; &lt;MultiDataTrigger &gt; &lt;MultiDataTrigger.Conditions&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(ItemsControl.AlternationIndex)}" Value="0" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(ListViewItem.IsSelected)}" Value="False" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(Panel.IsMouseOver)}" Value="False" /&gt; &lt;Condition Binding="{Binding Locked}" Value="False" /&gt; &lt;/MultiDataTrigger.Conditions&gt; &lt;Setter Property="Background" Value="DarkGray" /&gt; &lt;/MultiDataTrigger&gt; &lt;MultiDataTrigger &gt; &lt;MultiDataTrigger.Conditions&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(ItemsControl.AlternationIndex)}" Value="1" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(ListViewItem.IsSelected)}" Value="False" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(Panel.IsMouseOver)}" Value="False" /&gt; &lt;Condition Binding="{Binding Locked}" Value="False" /&gt; &lt;/MultiDataTrigger.Conditions&gt; &lt;Setter Property="Background" Value="SlateGray" /&gt; &lt;/MultiDataTrigger&gt; &lt;MultiDataTrigger&gt; &lt;MultiDataTrigger.Conditions&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(ListViewItem.IsSelected)}" Value="False" /&gt; &lt;Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=(Panel.IsMouseOver)}" Value="False" /&gt; &lt;Condition Binding="{Binding Locked}" Value="True" /&gt; &lt;/MultiDataTrigger.Conditions&gt; &lt;MultiDataTrigger.EnterActions&gt; &lt;BeginStoryboard&gt; &lt;Storyboard&gt; &lt;ColorAnimation Storyboard.TargetProperty="(Control.Background).(SolidColorBrush.Color)" From="Red" To="White" Duration="0:0:0.2" AutoReverse="True" RepeatBehavior="Forever" /&gt; &lt;/Storyboard&gt; &lt;/BeginStoryboard&gt; &lt;/MultiDataTrigger.EnterActions&gt; &lt;/MultiDataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; </code></pre>

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.
