Я хочу изменить цвет фона выбранного элемента в списке на другой цвет, поэтому я изменяю состояние выбора в шаблоне стиля:
<Style x:Key="ListBoxItemStyle1" TargetType="ListBoxItem">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="Padding" Value="0"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Border x:Name="LayoutRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Disabled">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="LayoutRoot">
<DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource TransparentBrush}"/>
</ObjectAnimationUsingKeyFrames>
<DoubleAnimation Duration="0" To=".5" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="ContentContainer"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselected"/>
<VisualState x:Name="Selected">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentContainer" Storyboard.TargetProperty="Foreground" Duration="0">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<SolidColorBrush Color="White"/>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="border" Storyboard.TargetProperty="Background" Duration="0">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<SolidColorBrush Color="YellowGreen"/>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<StackPanel x:Name="border" Orientation="Horizontal">
<ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Однако, когда я добавляю этот шаблон всписок, он загружает пустой, что неверно.Кроме того, я связываю элементы в списке со следующей таблицей элементов:
<DataTemplate x:Key="FlightsTemplate">
<StackPanel Orientation="Horizontal" Margin="3" Background="#FF171717" Height="35">
<TextBlock FontSize="19" Margin="1,0,0,0" TextAlignment="Center" Width="60" Text="{Binding Time}"/>
<TextBlock FontSize="19" Margin="1,0,0,0" TextAlignment="Center" Width="80" Text="{Binding Flight}"/>
<TextBlock FontSize="19" Margin="1,0,0,0" TextAlignment="Center" Width="150" Text="{Binding City}"/>
<TextBlock FontSize="19" Margin="1,0,0,0" TextAlignment="Center" Width="90" Text="{Binding Status}"/>
<TextBlock FontSize="19" Margin="1,0,0,0" TextAlignment="Center" Width="70" Text="{Binding Expected_Time}"/>
</StackPanel>
</DataTemplate>
