WPF实现带模糊搜索的DataGrid的示例代码

作者:干杯Archer、

这篇文章主要为大家详细介绍了WPF如何实现带模糊搜索的DataGrid,文中的示例代码讲解详细,具有一定的借鉴价值,需要的可以参考一下

带模糊搜索的DataGrid

前端代码 view

<Window
    x:Class="MVVM.Views.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:hc="https://handyorg.github.io/handycontrol"
    xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
    xmlns:prism="http://prismlibrary.com/"
    Title="{Binding Title}"
    Width="525"
    Height="350"
    prism:ViewModelLocator.AutoWireViewModel="True">
    <Grid>
        <DataGrid
            Name="dataGrid"
            AutoGenerateColumns="False"
            CanUserDeleteRows="True"
            ItemsSource="{Binding CollectionView}">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Id}" Header="Id" />
                <DataGridTextColumn Binding="{Binding FirstName}" Header="FirstName" />
                <DataGridTextColumn Binding="{Binding LastName}" Header="LastName" />
                <DataGridTextColumn Binding="{Binding Birthday}" Header="Birthday" />
                <DataGridTextColumn Binding="{Binding Salay}" Header="Salay" />
            </DataGrid.Columns>
        </DataGrid>
        <Grid VerticalAlignment="Bottom">
            <StackPanel Orientation="Horizontal">
                <Button
                    Width="120"
                    Command="{Binding AddEmployeeCommand}"
                    Content="New Employee" />
                <hc:TextBox
                    Name="filterTextBox"
                    Width="200"
                    Margin="5,0"
                    hc:InfoElement.Placeholder="Filter data by name"
                    Text="{Binding FilterText, UpdateSourceTrigger=PropertyChanged}" />
            </StackPanel>
        </Grid>
    </Grid>
</Window>

后端代码 ViewModel

using Prism.Commands;
using Prism.Mvvm;
using System.Collections.Generic;
using System.ComponentModel;
using System.Windows.Data;
using 带筛选的DataGrid.Core;

namespace MVVM.ViewModels
{
    public class MainWindowViewModel : BindableBase
    {
        public MainWindowViewModel()
        {
            AddEmployeeCommand = new DelegateCommand(AddEmployee);
            this.employees = new List<Employee>(Employee.FakeMany(10));
            CollectionView = CollectionViewSource.GetDefaultView(employees);
            CollectionView.Filter = (item) =>
            {
                if (string.IsNullOrEmpty(FilterText)) return true;
                var em = item as Employee;
                return em.FirstName.Contains(FilterText) || em.LastName.Contains(FilterText);
            };
        }

        List<Employee> employees;
        public DelegateCommand AddEmployeeCommand { get; set; }

        private ICollectionView collectionView;
        public ICollectionView CollectionView
        {
            get { return collectionView; }
            set { SetProperty(ref collectionView, value); }
        }

        private string filterText;
        public string FilterText
        {
            get { return filterText; }
            set { SetProperty(ref filterText, value,OnFilterTextChanged); }
        }

        public void OnFilterTextChanged()
        {
            CollectionView.Refresh();
        }

        public void AddEmployee()
        {
            employees.Add(Employee.FakeOne());
            CollectionView.Refresh();
        }
    }
}

Model 代码,引用了 Faker 这个库来创造假数据

using Bogus;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 带筛选的DataGrid.Core
{
    public class Employee
    {
        public int Id { get; set; }
        public string  FirstName { get; set; }
        public string LastName { get; set; }
        public DateOnly Birthday { get; set; }
        public int Salay { get; set; }

        public static Employee FakeOne() => employeeFaker.Generate();

        public static IEnumerable< Employee> FakeMany(int count ) => employeeFaker.Generate(count);


        private static readonly Faker<Employee> employeeFaker = new Faker<Employee>()
            .RuleFor(x => x.Id, x => x.IndexFaker)
            .RuleFor(x => x.FirstName, x => x.Person.FirstName)
            .RuleFor(x => x.LastName, x => x.Person.LastName)
            .RuleFor(x => x.Birthday, x => DateOnly.FromDateTime(x.Person.DateOfBirth))
            .RuleFor(x => x.Salay, x => x.Random.Int(6, 30) * 1000);
    }
}
