我有ListBox控制权；我将如何使用下面的代码ToolTip为每个设置。ListBoxItem

<ListBox Name="FillSelections" 
         VerticalContentAlignment="Stretch"
         Margin="1, 3, 1, 3"
         IsEnabled="True" 
         Grid.Column="0" 
         Background="Transparent"
         HorizontalContentAlignment="Center"
         SelectedItem="{Binding SelectedColor}"
         SelectionMode="Single"
         Style="{StaticResource HorizontalListBoxStyle}"
         ItemsSource="{Binding FillColors}"
         ItemTemplate="{StaticResource ColorsItemTemplate}">
</ListBox>

<DataTemplate x:Key="ColorsItemTemplate">
    <Border Width="20" 
            Height="16"
            BorderBrush="Black"
            BorderThickness="1">
        <Border.Background>
            <SolidColorBrush Color="{Binding}" />
        </Border.Background>
        <Path Stroke="Red" 
              StrokeThickness="3"
              x:Name="abc"
              Visibility="Hidden">
            <Path.Data>
                <LineGeometry StartPoint="0,16" EndPoint="20,0"/>
            </Path.Data>
        </Path>
    </Border>
    <DataTemplate.Triggers>
        <DataTrigger Binding="{Binding}" Value="#00FFFFFF">
            <Setter TargetName="abc" Property="Visibility" Value="Visible"/>
        </DataTrigger>
    </DataTemplate.Triggers>
</DataTemplate>

尝试这样的事情

<ListBox Width="400" Margin="10" 
         ItemsSource="{Binding Source={StaticResource myTodoList}}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Path=TaskName}" 
                       ToolTipService.ToolTip="{Binding Path=TheTooltipText}"/>
        </DataTemplate>
     </ListBox.ItemTemplate>
</ListBox>

当然，使用您的绑定源来调整 ItemsSource 绑定，并使用您实际想要显示的列表中对象的任何公共属性来调整绑定路径部分。

您可以为ListBoxItem. 所以类似于：

<Window x:Class="WpfApplication3.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style TargetType="ListBoxItem">
            <Setter Property="ToolTip">
                <Setter.Value>
                    <ToolTip>
                        <TextBlock>Hello</TextBlock>
                    </ToolTip>
                </Setter.Value>
            </Setter>
        </Style>
   </Window.Resources>
    <Grid>
        <ListBox>
            <ListBoxItem>
                <TextBlock Text="Hello" />
            </ListBoxItem>
        </ListBox>
    </Grid>
</Window>
