我想禁用垂直滚动条，它是ListBox的一部分，我想添加两个按钮，一个用于“向上”，一个用于“向下”。我将如何通过按钮实现功能来上下滚动列表框的内容。
这是我的列表框：
<ListBox x:Name="artikliList" ItemTemplate="{DynamicResource izabraniIzbornik}" Margin="310,105,395,10" Background="{DynamicResource gridArtikliColor}" ItemContainerStyle="{DynamicResource ListBoxItemStyle1}" ItemsPanel="{DynamicResource ItemsPanelTemplate1}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" BorderBrush="{DynamicResource borderBrushColor}" ScrollViewer.VerticalScrollBarVisibility="Disabled" BorderThickness="0,0,1,0" Style="{DynamicResource ListBoxStyle1}" >
<ListBox.Resources>
<Style TargetType="{x:Type ListBoxItem}">
<Setter Property="HorizontalContentAlignment"
Value="Stretch" />
<Style.Triggers>
<Trigger Property="IsMouseOver"
Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity"
To=".5"
Duration="0:0:0.4" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Opacity"
To="10"
Duration="0:0:0" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
<Setter Property="Background"
Value="Orange" />
<Setter Property="BorderBrush"
Value="SteelBlue" />
<Setter Property="BorderThickness"
Value="1" />
</Trigger>
</Style.Triggers>
</Style>
<DataTemplate x:Key="izabraniIzbornik">
<DockPanel Height="182" Width="182">
<DockPanel.Background>
<ImageBrush ImageSource="{Binding sifra, Converter={StaticResource ImageSourceConverter}}"/>
</DockPanel.Background>
<StackPanel VerticalAlignment="Bottom" Height="22" Background="#CC000000">
<Label Content="{Binding naziv}" Foreground="White" FontWeight="Bold" FontSize="12" HorizontalAlignment="Center"/>
</StackPanel>
</DockPanel>
</DataTemplate>
</ListBox.Resources>
</ListBox>

如果您想全部滚动，则需要将scrollviewer保留在列表框中。
默认模板内的按钮是重复按钮，而不是按钮。当您单击并按住它们时，会反复触发单击，这样您就可以重复滚动，而无需花费手指和鼠标。如果您确实想要按钮（如乔伊建议的那样）或项目滚动和重复按钮，我建议您要么进行页面滚动操作。
这里的代码看起来可以正常工作：https://www.codeproject.com/Questions/848015/VB-NET-WPF-Listbox-scroll-by-UP-DOWN-button
如果链接断开：
double ItemOffset=0;
private void ButtonUp_Click(object sender, RoutedEventArgs e)
{
ScrollViewerTest.ScrollToVerticalOffset(ScrollViewerTest.VerticalOffset - ItemOffset);
}
private void ButtonDown_Click(object sender, RoutedEventArgs e)
{
ScrollViewerTest.ScrollToVerticalOffset(ScrollViewerTest.VerticalOffset + ItemOffset);
}
private void ListBoxTest_Loaded(object sender, RoutedEventArgs e)
{
if (ListBoxTest.Items.Count == 0) return;
if (ItemOffset == 0)
{
((ListBoxItem)ListBoxTest.Items[0]).Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
ItemOffset = ((ListBoxItem)ListBoxTest.Items[0]).DesiredSize.Height;
}
}
您还希望隐藏垂直和水平滚动条。
ScrollViewer.VerticalScrollBarVisibility="Hidden"
使用每行高度的代码有点奇怪，但是替代方法还有其他缺点。
我认为您也可以向滚动条发出ScrollBar.LineUpCommand，但这是一个routedcommand，它们可以很灵活地开始工作。我认为您必须将命令目标设置为列表框内的垂直滚动条。

这可以通过XAML本身轻松实现。首先，您需要创建一种样式并将其应用于滚动条和列表框。
<Style x:Key="ScrollThumbs" TargetType="{x:Type Thumb}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Thumb}">
<Grid x:Name="Grid">
<Border x:Name="Rectangle1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Background="{StaticResource table_bg}" >
<Rectangle RadiusX="10" RadiusY="10" HorizontalAlignment="Center" VerticalAlignment="Center" Height="6" Width="6" Fill="{StaticResource scrolldot_bg}" />
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="Tag" Value="Horizontal">
<Setter TargetName="Rectangle1" Property="Width" Value="Auto" />
<Setter TargetName="Rectangle1" Property="Height" Value="7" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type ScrollBar}">
<Setter Property="Stylus.IsFlicksEnabled" Value="false" />
<Setter Property="Foreground" Value="LightGray" />
<Setter Property="Background" Value="DarkGray" />
<Setter Property="Width" Value="20" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollBar}">
<Border Background="White" Width="15" >
<Grid x:Name="GridRoot" >
<Grid.RowDefinitions>
<RowDefinition Height="15" />
<RowDefinition Height="0.00001*" />
<RowDefinition Height="15" />
</Grid.RowDefinitions>
<Button Grid.Row="2" Height="15" VerticalAlignment="Bottom" Command="ScrollBar.PageDownCommand"/>
<Button Grid.Row="0" Height="15" VerticalAlignment="Top" Command="ScrollBar.PageUpCommand"/>
<Track x:Name="PART_Track" Grid.Row="1" IsDirectionReversed="true" Focusable="false">
<Track.Thumb>
<Thumb x:Name="Thumb" Background="LightGray" Style="{DynamicResource ScrollThumbs}" />
</Track.Thumb>
<Track.IncreaseRepeatButton>
<RepeatButton x:Name="PageUp" Command="ScrollBar.PageDownCommand" Opacity="0" Focusable="false" />
</Track.IncreaseRepeatButton>
<Track.DecreaseRepeatButton>
<RepeatButton x:Name="PageDown" Command="ScrollBar.PageUpCommand" Opacity="0" Focusable="false" />
</Track.DecreaseRepeatButton>
</Track>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger SourceName="Thumb" Property="IsMouseOver" Value="true">
<Setter Value="{DynamicResource ButtonSelectBrush}" TargetName="Thumb" Property="Background" />
</Trigger>
<Trigger SourceName="Thumb" Property="IsDragging" Value="true">
<Setter Value="{DynamicResource DarkBrush}" TargetName="Thumb" Property="Background" />
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter TargetName="Thumb" Property="Visibility" Value="Collapsed" />
</Trigger>
<Trigger Property="Orientation" Value="Horizontal">
<Setter TargetName="GridRoot" Property="LayoutTransform">
<Setter.Value>
<RotateTransform Angle="-90" />
</Setter.Value>
</Setter>
<Setter TargetName="PART_Track" Property="LayoutTransform">
<Setter.Value>
<RotateTransform Angle="-90" />
</Setter.Value>
</Setter>
<Setter Property="Width" Value="Auto" />
<Setter Property="Height" Value="15" />
<Setter TargetName="Thumb" Property="Tag" Value="Horizontal" />
<Setter TargetName="PageDown" Property="Command" Value="ScrollBar.PageLeftCommand" />
<Setter TargetName="PageUp" Property="Command" Value="ScrollBar.PageRightCommand" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
以上样式创建带有向上和向下按钮的滚动条。 我将此应用于我自己的项目，因此您可能需要根据自己的需要对其进行自定义！
