You dont need to give column names manually in xaml. Just set AutoGenerateColumns property to true and your list will be automatically binded to DataGrid. refer code. XAML Code:

<Grid>
    <DataGrid x:Name="MyDatagrid" AutoGenerateColumns="True" Height="447" HorizontalAlignment="Left" Margin="20,85,0,0" VerticalAlignment="Top" Width="799"  ItemsSource="{Binding Path=ListTest, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"  CanUserAddRows="False"> </Grid>

C#

Public Class Test 
{
    public string m_field1_Test{get;set;}
    public string m_field2_Test { get; set; }
    public Test()
    {
        m_field1_Test = "field1";
        m_field2_Test = "field2";
    }
    public MainWindow()
    {

        listTest = new List<Test>();

        for (int i = 0; i < 10; i++)
        {
            obj = new Test();
            listTest.Add(obj);

        }

        this.MyDatagrid.ItemsSource = ListTest;

        InitializeComponent();

    }

if you do not expect that your list will be recreated then you can use the same approach as you ve used for Asp Net  instead of DataSource this property in WPF is usually named ItemsSource      this dataGrid1 ItemsSource   list    But if you would like to replace your list with new collection instance then you should consider using databinding

You should do it in the xaml code    lt DataGrid ItemsSource   Binding list         gt           lt  DataGrid gt    I would advise you to use an ObservableCollection as your backing collection  as that would propagate changes to the datagrid  as it implements INotifyCollectionChanged

Actually  to properly support sorting  filtering  etc  a CollectionViewSource should be used as a link between the DataGrid and the list  like this    lt Window Resources gt     lt CollectionViewSource x Key  ItemCollectionViewSource  CollectionViewType  ListCollectionView   gt   lt  Window Resources gt       The DataGrid line looks like this    lt DataGrid   DataContext   StaticResource ItemCollectionViewSource     ItemsSource   Binding     AutoGenerateColumns  False  gt      In the code behind  you link CollectionViewSource with your link   CollectionViewSource itemCollectionViewSource  itemCollectionViewSource    CollectionViewSource  FindResource  ItemCollectionViewSource     itemCollectionViewSource Source   itemList    For detailed example see my article on CoedProject  http   www codeproject com Articles 683429 Guide-to-WPF-DataGrid-formatting-using-bindings
