Question

如何使用WPF中的按钮按部分滚动？

我有下一个ListBox：

我需要左边的每个箭头（按钮）和正确执行滚动操作（后退和下一步）

这是我的ListBox代码（因为按钮代码不是那么重要，我只是粘贴ListBox代码）

<ListBox Grid.Column="1" Grid.Row="1" Name="CategoriesListBox" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Hidden" Background="#00FFFFFF" BorderBrush="{x:Null}">
                    <ListBox.ItemsPanel>
                        <ItemsPanelTemplate>
                            <UniformGrid Rows="2" VerticalAlignment="Center" Background="#00FFFFFF"/>
                        </ItemsPanelTemplate>
                    </ListBox.ItemsPanel>
                    <ListBox.ItemContainerStyle>
                        <Style TargetType="{x:Type ListBoxItem}">
                            <Setter Property="Focusable" Value="False"/>
                        </Style>
                    </ListBox.ItemContainerStyle>
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <Button Height="{Binding ElementName=DummyGrid, Path=ActualHeight}" Width="{Binding ElementName=DummyGrid, Path=ActualWidth}" Margin="2">
                                <Button.Content>
                                    <Viewbox Stretch="Uniform" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
                                        <TextBlock Foreground="White" FontFamily="/BundyPOS;component/Fonts/#HelveticaRounded" TextAlignment="Center" Margin="7" Text="{Binding a}"></TextBlock>
                                    </Viewbox>
                                </Button.Content>
                                <Button.Style>
                                    <Style TargetType="{x:Type Button}">
                                        <Setter Property="Background" Value="{Binding color}"/>
                                        <Setter Property="Template">
                                            <Setter.Value>
                                                <ControlTemplate TargetType="{x:Type Button}">
                                                    <Border CornerRadius="15" BorderBrush="White" BorderThickness="2,2,2,2" Background="{TemplateBinding Background}">
                                                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                                    </Border>
                                                </ControlTemplate>
                                            </Setter.Value>
                                        </Setter>
                                        <Style.Triggers>
                                            <Trigger Property="IsMouseOver" Value="True">
                                                <Setter Property="Background" Value="#3cb878"/>
                                                <Setter Property="Foreground" Value="Black"/>
                                            </Trigger>
                                        </Style.Triggers>
                                    </Style>
                                </Button.Style>
                            </Button>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>

我无法执行ListBox.ScrollIntoView(categoryItem[position]);因为ListBox每行可能有不同的行或值。有没有像＆＃34; scrollToHorizontalOffset＆＃34;？

这样的功能

试试这个代码..这是一个参考

在wpf中创建一个像这样的窗口......

查看上面窗口的cs代码

  using System.Windows.Navigation;
  using System.Windows.Shapes;
  using System.Collections.ObjectModel;

 namespace AutoScrollListBox
{
public partial class MainWindow : Window
{
    ObservableCollection<EquipmentItem> m_selectedEquipmentHorizontal = new ObservableCollection<EquipmentItem>();
    ObservableCollection<EquipmentItem> m_selectedEquipmentVertical = new ObservableCollection<EquipmentItem>();


    public MainWindow()
    {
        InitializeComponent();
    }


    protected override void OnInitialized( EventArgs e )
    {
        base.OnInitialized( e );

        ObservableCollection<EquipmentItem> equipmentList1 = new ObservableCollection<EquipmentItem>();
        this.horizontalListBox.ItemsSource = equipmentList1;
        CreateEquipments( equipmentList1, "Tank-" );
        this.horizontalSelectedItemsListBox.ItemsSource = m_selectedEquipmentHorizontal;

        ObservableCollection<EquipmentItem> equipmentList2 = new ObservableCollection<EquipmentItem>();
        this.verticalListBox.ItemsSource = equipmentList2;
        CreateEquipments( equipmentList2, "Tank-" );
        this.verticalSelectedItemsListBox.ItemsSource = m_selectedEquipmentVertical;
    }


    private ObservableCollection<EquipmentItem> CreateEquipments( ObservableCollection<EquipmentItem> equipmentList, string prefix )
    {
        int maxItemCount = 20;
        for( int i = 0; i < maxItemCount; i++ )
        {
            equipmentList.Add( new EquipmentItem() { Name = prefix + i.ToString(), CampaignName = "Batch_ " + i.ToString() } );
        }
        return equipmentList;
    }



    private void horizontalListBox_SelectionChanged( object sender, SelectionChangedEventArgs e )
    {
        if( e.AddedItems.Count > 0 )
        {
            foreach( EquipmentItem item in e.AddedItems )
            {
                m_selectedEquipmentHorizontal.Add( item );
            }
        }

        if( e.RemovedItems.Count > 0 )
        {
            foreach( EquipmentItem item in e.RemovedItems )
            {
                m_selectedEquipmentHorizontal.Remove( item );
            }
        }
    }

    private void verticalListBox_SelectionChanged( object sender, SelectionChangedEventArgs e )
    {
        if( e.AddedItems.Count > 0 )
        {
            foreach( EquipmentItem item in e.AddedItems )
            {
                m_selectedEquipmentVertical.Add( item );
            }
        }

        if( e.RemovedItems.Count > 0 )
        {

            {
                m_selectedEquipmentVertical.Remove( item );
            }
        }
    }

    }
  }

然后为Window的更改样式创建一个ResourceDirectory，就像这样

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<!-- Border Brushes -->

<LinearGradientBrush x:Key="NormalBorderBrush" StartPoint="0,0" EndPoint="0,1">
    <GradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#CCC" Offset="0.0"/>
            <GradientStop Color="#444" Offset="1.0"/>
        </GradientStopCollection>
    </GradientBrush.GradientStops>
</LinearGradientBrush>

您可以使用Binding.So将项目添加到ListBox中，为其创建一个类。

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;

    namespace AutoScrollListBox
    {
        public class EquipmentItem
        {
            public string Name { get; set; }
            public string CampaignName { get; set; }
            public string ImagePath { get; set; }
         }
     }

使用按钮WPF滚动ListBox
