问题描述

我搜索示例或示例以通过文本框过滤 WPF DataGrid 列元素.

I search an example or sample to filter the WPF DataGrid column elements by a textbox.

类似于this(给定的示例使用WPFToolkit...显然被微软抛弃了...)

Something similar to this (the given example uses a WPFToolkit... apparently abandoned by Microsoft...)

XAML

<Canvas>
    <DataGrid Height="200" Name="dataGrid1" Width="200" Canvas.Top="23" />
    <TextBox  Name="textBox1" Width="120" />
</Canvas>

CS:

public partial class MainWindow : Window
{
    private List<Personne> persons;
    ICollectionView cvPersonnes;

    public MainWindow()
    {
        InitializeComponent();

        persons = new List<Personne>();

        persons.Add(new Personne() { Id = 1, Nom = "Jean-Michel", Prenom = "BADANHAR" });
        persons.Add(new Personne() { Id = 1, Nom = "Gerard", Prenom = "DEPARDIEU" });
        persons.Add(new Personne() { Id = 1, Nom = "Garfild", Prenom = "THECAT" });
        persons.Add(new Personne() { Id = 1, Nom = "Jean-Paul", Prenom = "BELMONDO" });

        cvPersonnes = CollectionViewSource.GetDefaultView(persons);

        if (cvPersonnes != null)
        {
            dataGrid1.AutoGenerateColumns = true;
            dataGrid1.ItemsSource = cvPersonnes;
            cvPersonnes.Filter = TextFilter;
        }
    }

    public bool TextFilter(object o)
    {
        Personne p = (o as Personne);
        if (p == null)
            return false;

        if (p.Nom.Contains(textBox1.Text))
            return true;
        else
            return false;
    }

}

public class Personne
{
    public int Id { get; set; }
    public string Nom { get; set; }
    public string Prenom { get; set; }
}

推荐答案

您可以通过将 DataGrid 中的项绑定到支持过滤的 ICollectionView 来对其进行过滤.

You can filter the Items in the DataGrid by binding it to an ICollectionView that supports filtering.

Details here for .NET 4. The process is the same for .NET 4.5, but it seems the documentation has been lost. There's a small mention to it here under the "Grouping, Sorting, and Filtering" heading.
