我是Xaml的新手,因此我被卡在这里。我用谷歌搜索了许多不同的方法,但是都没有用:-(我希望有人在这里有个主意,可以为我提供帮助:-)
借助互联网上的一些教程,我得到了这个TreeView。它像一个咒语一样工作:-)
<TreeView>
<TreeViewItem ItemsSource="{Binding Data.Number}">
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Width="15" Margin="5 0 5 0" Source="image.ico"/>
<TextBlock Text="{Binding Data.ID}"/>
<TextBlock Text=" [" Foreground="Blue"/>
<TextBlock Text="{Binding Data.Number.Count}" Foreground="Blue"/>
<TextBlock Text="]" Foreground="Blue"/>
</StackPanel>
</TreeViewItem.Header>
<TreeViewItem.ItemTemplate>
<DataTemplate>
<TreeViewItem Header="{Binding ItemID}">
<TreeViewItem ItemsSource="{Binding ItemInfo}">
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Width="15" Margin="5 0 5 0" Source="image.ico"/>
<TextBlock Text="Items"/>
<TextBlock Text=" [" Foreground="Blue"/>
<TextBlock Text="{Binding ItemInfo.Count}" Foreground="Blue"/>
<TextBlock Text="]" Foreground="Blue"/>
</StackPanel>
</TreeViewItem.Header>
<TreeViewItem.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Value.Number}"/>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
<TreeViewItem ItemsSource="{Binding SetInfo}">
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Width="15" Margin="5 0 5 0" Source="image.ico"/>
<TextBlock Text="Sets"/>
<TextBlock Text=" [" Foreground="Blue"/>
<TextBlock Text="{Binding SetInfo.Count}" Foreground="Blue"/>
<TextBlock Text="]" Foreground="Blue"/>
</StackPanel>
</TreeViewItem.Header>
<TreeViewItem.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Value.ID}"/>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
<TreeViewItem ItemsSource="{Binding GroupInfo}">
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Width="15" Margin="5 0 5 0" Source="image.ico"/>
<TextBlock Text="Groups"/>
<TextBlock Text=" [" Foreground="Blue"/>
<TextBlock Text="{Binding GroupInfo.Count}" Foreground="Blue"/>
<TextBlock Text="]" Foreground="Blue"/>
</StackPanel>
</TreeViewItem.Header>
<TreeViewItem.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Value.Number}"/>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
</TreeViewItem>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
</TreeView>
现在的问题是我希望所选项目(单击鼠标)变粗体。但仅选中的项目(不包括下面或上面的项目)。物品在哪个级别上都没有关系。
我尝试了很多变化,但是没有一个起作用。这两个是最好的,但是他们总是选择一个孔节点或只是顶部节点,我无法将其分解为一个节点。
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}"/>
<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/>
<Setter Property="FontWeight" Value="Normal"/>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
</Trigger>
</Style.Triggers>
</Style>
</TreeView.ItemContainerStyle>
<TextBlock.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type TreeViewItem}}, FallbackValue=False}" Value="True">
<Setter Property="TextBlock.FontWeight" Value="Bold" />
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
答案 0 :(得分:0)
您可以尝试这个Style
吗?
<TreeView.Resources>
<Style TargetType="{x:Type TreeViewItem}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter Property="FontWeight" Value="Normal"/>
</Trigger>
</Style.Triggers>
</Style>
</TreeView.Resources>
