Binding DataGrid to List in wpf

Question

I trying to bind a List to a DataGrid. Here is the code snippet:

public class Parson
{

    public string LastName { get; set; }
    public string FirstName { get; set; }

    public Parson(string lastName, string firstName)
    {
        LastName = lastName;
        FirstName = firstName;
    }
}

public class Persons : List<Parson>
{

    // Parameterless constructor      
    public Persons()
    {
    }
    public new void Add(Person parson)
    {
        base.Add(parson);
    }
}

the code behind:

    Persons persons = new Persons();
        persons.Add(new Parson("New","Person");
        dataGrid1.DataContext = persons;

xaml:

<my:DataGrid  Name="dataGrid1" 
    xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" 
    CanUserAddRows="True" 
    ItemsSource="{Binding}" 
    AutoGenerateColumns="False">
        <my:DataGrid.Columns>
            <my:DataGridTextColumn Header="First Name" Binding="{Binding Path=FirstName}"/>
            <my:DataGridTextColumn Header="Last Name" Binding="{Binding Path=LastName}"/>
        </my:DataGrid.Columns>
    </my:DataGrid>

the result is that an empty grid is display! anyone know why?

Answer 1

Try setting the ItemsSource instead of DataContext, and remove the ItemsSource={Binding} from your XAML. That may do the trick.

Edit:

I just checked some code I wrote that uses the same DataGrid control (WPF Toolkit), and I do in fact set the ItemsSource instead of DataContext. If you need an example, let me know.

Answer 2

In your DataGrid try:

ItemsSource="{Binding Path=.}"

This has worked sucessfully for me.

Answer 3

I'm not sure that you can bind directly to a pure List object, I think that your "Persons" List object needs to be an ObservableCollection, or BindingList or other collection that can be bound to.
