WPF实现列表分页控件的示例代码分享

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。

                                    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;

        }

    }

}
