  1. POHow to highlight selected row in WPF Listview control with alternating background
    text
    copied!<p>I am using VS 2008 with 3.5 of the .NET framework. I have set up my code to alternate the background lines in a WPF ListView control. One color used is white. The other color used is a light shade of green. When a white line is clicked on, it highlights the line in light blue. When a green line is clicked on, there is no highlighting and the background color remains light green. I have tried specifying the HighlightBrushKey and the ControlBrushKey in XAML, but they had no effect. What do I need to do in order for the green lines to be highlighted when clicked on?</p> <p>Here is the XAML code:</p> <pre><code>&lt;!-- Define the resource for the alternating background background used in the ListView objects. --&gt; &lt;StackPanel.Resources&gt; &lt;Style x:Key="alternatingListViewItemStyle" TargetType="{x:Type ListViewItem}"&gt; &lt;Style.Resources&gt; &lt;!-- Foreground for Selected ListViewItem --&gt; &lt;!-- &lt;SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/&gt; --&gt; &lt;!-- Background for Selected ListViewItem --&gt; &lt;SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Green"/&gt; &lt;SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Brown"/&gt; &lt;/Style.Resources&gt; &lt;Style.Triggers&gt; &lt;!-- Tried setting the background property here, but this did not work. &lt;DataTrigger Binding="{Binding Path=RowSelected}" Value="True"&gt; &lt;Setter Property="Background" Value="Gainsboro" /&gt; &lt;Setter Property="FontWeight" Value="Bold" /&gt; &lt;/DataTrigger&gt; --&gt; &lt;!-- setting up triggers for alternate background colors --&gt; &lt;Trigger Property="ItemsControl.AlternationIndex" Value="1"&gt; &lt;Setter Property="Background" Value="#FFD9F2BF"&gt;&lt;/Setter&gt; &lt;/Trigger&gt; &lt;!-- setting up triggers for alternate background colors &lt;Trigger Property="ItemsControl" Value="1"&gt; &lt;Setter Property="Background" Value="#FFD9F2BF"&gt;&lt;/Setter&gt; &lt;/Trigger&gt; --&gt; &lt;Trigger Property="ItemsControl.AlternationIndex" Value="2"&gt; &lt;Setter Property="Background" Value="White"&gt;&lt;/Setter&gt; &lt;/Trigger&gt; &lt;/Style.Triggers&gt; &lt;!-- setting row height here --&gt; &lt;/Style&gt; &lt;/StackPanel.Resources&gt; &lt;ListView x:Name="ListView1" ItemContainerStyle="{StaticResource alternatingListViewItemStyle}" AlternationCount="2" SelectionChanged="ListView1_SelectionChanged" SelectionMode="Multiple" HorizontalAlignment="Left" ItemsSource = "{Binding ElementName=LobbyWindow, Path=ListCollection1}"&gt; &lt;ListView.View&gt; &lt;GridView&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding Game}"&gt; &lt;GridViewColumnHeader Content="Game" FontWeight="Bold" /&gt; &lt;/GridViewColumn&gt; &lt;GridViewColumn DisplayMemberBinding="{Binding Stakes}"&gt; &lt;GridViewColumnHeader Content="Stakes" Width="68" FontWeight="Bold" /&gt; &lt;/GridViewColumn&gt; &lt;GridViewColumn Width="30" DisplayMemberBinding="{Binding Seats}"&gt; &lt;GridViewColumnHeader Content="Seats" FontWeight="Bold" /&gt; &lt;/GridViewColumn&gt; &lt;/GridView&gt; &lt;/ListView.View&gt; &lt;/ListView&gt; </code></pre> <p>I also have a Selection_Changed event defined in ListView1, but don't know how to grab the correct property or view element out in order to change the background color for that line:</p> <pre><code>private void ListView1_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e) { ListView listview = sender as ListView; } </code></pre> <p>Any suggestions in XAML or C# code behind would be appreciated.</p>
