WPF实现列表分页控件的示例代码分享
原创
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

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);
????????????}
????????}
????}
}

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;
????????}
