wpf - 在文本框上过滤 DataGrid

Question

我搜索示例或示例以按文本框过滤 WPF DataGrid 列元素。



类似于 this 的东西(给定的示例使用 WPFToolkit ......显然被微软放弃了......)

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; }
}

我在各个网站上看到很多关于这件事的...

要过滤后者是使用数据表作为源的数据网格，这在以下代码中很常见:

DataTable dt = new DataTable("Table1");

//fill your datatable...

//after fill...
dataGrid1.DataContext = dt;
IBindingListView blv = dt.DefaultView;
blv.Filter = "NAME = 'MOISES'";
