WPF 之列表分页控件

框架使用大于等于.NET40。

Visual Studio 2022。

项目使用 MIT 开源许可协议。

新建Pagination自定义控件继承自Control。

正常模式分页 在外部套Grid分为0 - 5列：

Grid.Column 0 总页数共多少300条。

Grid.Column 1 输入每页显示多少10条。

Grid.Column 2 上一页按钮。

Grid.Column 3 所有页码按钮此处使用ListBox。

Grid.Column 4 下一页按钮。

Grid.Column 5 跳转页1码输入框。

精简模式分页 在外部套Grid分为0 - 9列：

Grid.Column 0 总页数共多少300条。

Grid.Column 2 输入每页显示多少10条。

Grid.Column 3 条 / 页。

Grid.Column 5 上一页按钮。

Grid.Column 7 跳转页1码输入框。

Grid.Column 9 下一页按钮。

每页显示与跳转页码数控制只允许输入数字，不允许粘贴。

实现代码

<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition Width="Auto"/>

                                        <UniformGrid Rows="1"/>
                                    </ItemsPanelTemplate>
                                </ListBox.ItemsPanel>
                            </ListBox>
                            <Button Grid.Column="4" 
                                    Command="{x:Static controls:Pagination.NextCommand}">
                                <Path Width="7" Height="10" Stretch="Fill" 
                                      Fill="{Binding Foreground,RelativeSource={RelativeSource AncestorType=Button}}"
                                      Data="{StaticResource PathNext}"/>
                            </Button>
                            <StackPanel Grid.Column="5" Orientation="Horizontal">
                                <TextBlock Text=" 前往 " VerticalAlignment="Center"/>
                                <TextBox x:Name="PART_JumpPageTextBox"
                                         TextAlignment="Center" 
                                         ContextMenu="{x:Null}"
                                         Width="60" VerticalContentAlignment="Center"
                                         MinWidth="0"
                                         FontSize="{TemplateBinding FontSize}" />
                                <TextBlock Text=" 页" VerticalAlignment="Center"/>
                            </StackPanel>
                        </Grid>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <Trigger Property="IsLite" Value="true">
                <Setter Property="Template" Value="{StaticResource LitePagerControlTemplate}"/>
            </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary>

3）创建PaginationExampleVM.cs如下：

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
namespace WPFDevelopers.Samples.ViewModels
{
    public class PaginationExampleVM : ViewModelBase
    {
        private List<int> _sourceList = new List<int>();
        public PaginationExampleVM()
        {
            _sourceList.AddRange(Enumerable.Range(1, 300));
            Count = 300;
            CurrentPageChanged();
        }
        public ObservableCollection<int> PaginationCollection { get; set; } = new ObservableCollection<int>();
        private int _count;
        public int Count
        {
            get { return _count; }
            set { _count = value;  this.NotifyPropertyChange("Count"); CurrentPageChanged(); }
        }
        private int _countPerPage = 10;
        public int CountPerPage
        {
            get { return _countPerPage; }
            set { _countPerPage = value; this.NotifyPropertyChange("CountPerPage"); CurrentPageChanged(); }
        }
        private int _current = 1;
        public int Current
        {
            get { return _current; }
            set { _current = value; this.NotifyPropertyChange("Current"); CurrentPageChanged(); }
        }
        private void CurrentPageChanged()
        {
            PaginationCollection.Clear();
            foreach (var i in _sourceList.Skip((Current - 1) * CountPerPage).Take(CountPerPage))
            {
                PaginationCollection.Add(i);
            }
        }
    }
}

4）使用 PaginationExample.xaml 如下：

<UserControl x:Class="WPFDevelopers.Samples.ExampleViews.PaginationExample"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:wpfdev="https://github.com/WPFDevelopersOrg/WPFDevelopers"
             xmlns:local="clr-namespace:WPFDevelopers.Samples.ExampleViews"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <UserControl.Resources>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="Foreground" Value="{DynamicResource PrimaryTextSolidColorBrush}" />
            <Setter Property="FontSize" Value="{StaticResource NormalFontSize}"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
        </Style>
    </UserControl.Resources>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="50"/>
            <RowDefinition/>
            <RowDefinition Height="40"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="2*"/>
            <ColumnDefinition Width="30"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <TextBlock Text="正常模式分页" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        <TextBlock Grid.Column="2" Text="精简模式分页" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        <ListBox Grid.Row="1" Grid.Column="0" ItemsSource="{Binding NormalPaginationViewModel.PaginationCollection}" Margin="20,0,0,0"/>
        <ListBox Grid.Row="1" Grid.Column="2" ItemsSource="{Binding LitePaginationViewModel.PaginationCollection}" Margin="0,0,20,0"/>
        <wpfdev:Pagination Grid.Row="2" Grid.Column="0" IsLite="False"  Margin="20,0,0,0"
                             Count="{Binding NormalPaginationViewModel.Count,Mode=TwoWay}"
                             CountPerPage="{Binding NormalPaginationViewModel.CountPerPage,Mode=TwoWay}"
                             Current="{Binding NormalPaginationViewModel.Current,Mode=TwoWay}"/>
        <wpfdev:Pagination Grid.Row="2" Grid.Column="2" IsLite="true"  Margin="0,0,20,0"
                             Count="{Binding LitePaginationViewModel.Count,Mode=TwoWay}"
                             CountPerPage="{Binding LitePaginationViewModel.CountPerPage,Mode=TwoWay}"
                             Current="{Binding LitePaginationViewModel.Current,Mode=TwoWay}"/>
    </Grid>
</UserControl>

5）使用PaginationExample.xaml.cs如下：

using System.Windows.Controls;
using WPFDevelopers.Samples.ViewModels;
namespace WPFDevelopers.Samples.ExampleViews
{
    /// <summary>
    /// PaginationExample.xaml 的交互逻辑
    /// </summary>
    public partial class PaginationExample : UserControl
    {
        public PaginationExampleVM NormalPaginationViewModel { get; set; } = new PaginationExampleVM();
        public PaginationExampleVM LitePaginationViewModel { get; set; } = new PaginationExampleVM();
        public PaginationExample()
        {
            InitializeComponent();
            this.DataContext = this;
        }
    }
}

实现效果
