如何在WPF ListBox中添加标头
如何在WPF ListBox中添加标头
提问于 2021-11-04 13:55:56
如何在WPF中的ListBox中添加一个头？我有下面的代码，"Header - ..“text是我想要下面直到下一个标题的所有项目的标题/组名称：
<ListBox
x:Name="ItemsListBox"
Margin="0 16 0 16"
Style="{StaticResource MaterialDesignNavigationPrimaryListBox}">
<ListBox.Resources>
<Style TargetType="ScrollBar" BasedOn="{StaticResource MaterialDesignScrollBarMinimal}"/>
</ListBox.Resources>
Header - Config
<Separator/>
<ListBoxItem>Config menu 1</ListBoxItem>
<ListBoxItem>Config menu 2</ListBoxItem>
<ListBoxItem>Config menu 3</ListBoxItem>
<ListBoxItem>Config menu 4</ListBoxItem>
<ListBoxItem>Config menu 5</ListBoxItem>
<ListBoxItem>Config menu 6</ListBoxItem>
<ListBoxItem>Config menu 7</ListBoxItem>
Header - Tasks
<Separator/>
<ListBoxItem>Task menu 1</ListBoxItem>
<ListBoxItem>Task menu 2</ListBoxItem>
<ListBoxItem>Task menu 3</ListBoxItem>
<ListBoxItem>Task menu 4</ListBoxItem>
<ListBoxItem>Task menu 5</ListBoxItem>
<ListBoxItem>Task menu 6</ListBoxItem>
<ListBoxItem>Task menu 7</ListBoxItem>
<Separator/>
</ListBox>下面是我想要实现的一个示例：
它不需要每个列表框项目都有图标，但主要是像Options，User Settings和Administraton这样的标题。
我只看到其他线程中的人有多列，但这创建了两列不同的数据，我希望有一列，但只添加标题的粗体和大小更高的字体，以分隔不同的菜单彼此。
我在WPF中使用了MaterialDesign主题--不管它是否重要或相关……
谢谢!
编辑1:正如我之前没有提到的-它不一定是一个ListBox，我使用它是因为我在编写菜单的代码中使用了它：
<materialDesign:DrawerHost
IsLeftDrawerOpen="{Binding ElementName=MenuToggleButton, Path=IsChecked}">
<materialDesign:DrawerHost.LeftDrawerContent>
<DockPanel MinWidth="220">
<ToggleButton
Style="{StaticResource MaterialDesignHamburgerToggleButton}"
DockPanel.Dock="Top"
HorizontalAlignment="Right"
Margin="16"
IsChecked="{Binding ElementName=MenuToggleButton, Path=IsChecked, Mode=TwoWay}"/>
<TextBox
x:Name="DemoItemsSearchBox"
Text="{Binding SearchKeyword, UpdateSourceTrigger=PropertyChanged}"
DockPanel.Dock="Top"
Margin="16, 4"
Width="200"
materialDesign:HintAssist.Hint="Search"
materialDesign:HintAssist.IsFloating="True"

对于硬编码的xaml，非MVVM解决方案，我会使用菜单而不是ListBox。我通常只使用ListBoxes绑定到数据/项的列表。
我们也可以用这个方法来实现你的图标。
显然，你喜欢的样式，但如果你拿出你的ListBox，你可以替换为菜单，如下所示：
<ScrollViewer>
<Menu>
<Menu.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel />
</ItemsPanelTemplate>
</Menu.ItemsPanel>
<Menu.Resources>
<Style TargetType="ScrollBar" BasedOn="{StaticResource MaterialDesignScrollBarMinimal}"/>
</Menu.Resources>
<TextBlock Text="Config" FontWeight="Bold" FontSize="20" IsEnabled="False" />
<Separator/>
<MenuItem>
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 1" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 2" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 3" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 4" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 5" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 6" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<MenuItem >
<MenuItem.Header>
<DockPanel>
<materialDesign:PackIcon Kind="Settings" Margin="3" />
<TextBlock Text="Config item 7" Margin="3" />
</DockPanel>
</MenuItem.Header>
</MenuItem>
<TextBlock Text="Tasks" FontWeight="Bold" FontSize="20" />
<Separator/>
<MenuItem Header="Task item 1" />
<MenuItem Header="Task item 2" />
<MenuItem Header="Task item 3" />
<MenuItem Header="Task item 4" />
<MenuItem Header="Task item 5" />
<MenuItem Header="Task item 6" />
<MenuItem Header="Task item 7" />
</Menu>
</ScrollViewer>这会产生(我只在上半部分添加了图标，以说明如何)：
