BindingListView<T> is a project hosted on GotDotNet that gives you search, sorting and filtering capabilities to a plain BindingList. For example if you have the following Person entity:

public class Person
{
    string firstName = string.Empty;
    int age = 0;

    public string FirstName
    {
        get { return firstName; }
        set { firstName = value; }
    }

    public int Age
    {
        get { return age; }
        set { age = value; }
    }

    public Person(string firstName, int age)
    {
        this.firstName = firstName;
        this.age = age;
    }
}

And you want to have a collection of persons bind to a datagrid, you can simply write the following:

What if you need to do some filtering, or simply sorting on the datagrid? Therefore you would need to create a custom collection class that implements a bunch of interfaces for having sorting, filtering and searching capabilities.

The BindingListView<T> class has all these functionalities built-in. You simply have to pass a list, and bind the BindingListView to the datagrid. The same way you would do with a DataSet and DataView. This means:

Filtering is done through the Filter property and uses anonymous delegates. So for example to filter all persons that are less than 30, you can write:

personsView.Filter = BindingListView<Person>.CreateItemFilter(new Predicate<Person>(
    delegate(Person person)
    {
        return (person.Age < 30);
    }
));

You can also merge multiple sources to one view (functionality that the DataView doesn't support) through the AggregatedBindingListView<T>.
