Blend 修改TreeViewItem样式
Blend 修改TreeViewItem样式
1、用Blend for Visual Studio 2019 新建Wpf项目，拖动一个TreeView控件到Grid上
<Grid>
<TreeView>
<TreeViewItem Header="TreeViewItem">
<TreeViewItem Header="TreeViewItem"/>
</TreeViewItem>
<TreeViewItem Header="TreeViewItem">
<TreeViewItem Header="TreeViewItem"/>
</TreeViewItem>
</TreeView>
</Grid>
2、在绘图窗口选中TreeViewItem，右键编辑模版->编辑副本
3、绘制水平、垂直虚线（参考博文）
在TreeViewItem ControlTemplate模板中增加
<!-- Connecting Lines -->
<!-- Horizontal line -->
<Rectangle x:Name="HorLn"
Margin="10,0,0,0"
Height="1"
Stroke="#FF565656"
SnapsToDevicePixels="True"
StrokeDashCap="Square"
StrokeDashOffset="1"/>
<!-- Vertical line -->
<Rectangle x:Name="VerLn"
Width="1"
Stroke="#FF565656"
Margin="0,0,-2,0"
Grid.RowSpan="2"
SnapsToDevicePixels="true"
Fill="White"
StrokeDashCap="Square"
StrokeDashArray="1,5"/>
对于当前层最后一个节点，不再画它水平方向线以下的垂直线，这里使用到转换器完成
class TreeViewLineConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
var item = value as TreeViewItem;
ItemsControl ic = ItemsControl.ItemsControlFromItemContainer(item);
return ic.ItemContainerGenerator.IndexFromContainer(item) == ic.Items.Count - 1;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return false;
}
}
触发器需增加代码
<!-- 当前层最后一个元素不画下方垂直线 -->
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource LineConverter}}" Value="true">
<Setter TargetName="VerLn" Property="Height" Value="15"/>
<Setter TargetName="VerLn" Property="VerticalAlignment" Value="Top"/>
</DataTrigger>
<!-- Root第一个元素不显示上方垂直线 -->
<Trigger Property="TabIndex" Value="1">
<Setter TargetName="VerLn" Property="Margin" Value="0,12,1,0"/>
<Setter TargetName="VerLn" Property="Height" Value="Auto"/>
</Trigger>

4、TreeViewItem显示图片以及名称
<TreeView ItemsSource="{Binding Tools}">
<TreeView.Resources>
<local:UriToImageSourceConverter x:Key="UriToImageSource"/>
</TreeView.Resources>
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Nodes}">
<DockPanel>
<Image Source="{Binding PicPath, Converter={StaticResource UriToImageSource}}" Width="25" Height="25"/>
<TextBlock Text="{Binding Name}" FontSize="13" VerticalAlignment="Center" Margin="3,0,0,0"/>
</DockPanel>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
Tools是数据集合，节点集合Nodes。PicPath保存图片名称，使用UriToImageSourceConverter转换器转换成BitmapImage类型显示。
class UriToImageSourceConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
string path = (string)value;
if (string.IsNullOrEmpty(path))
{
path = "pack://application:,,,/WpfApp2;component/position.ico";//默认图片
}
return new BitmapImage(new Uri(path, UriKind.Absolute));
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return false;
}
}
效果图如下
