如何在WPF中用DataGrid填充窗口空白

<Grid>
    <DataGrid x:Name="myDataGrid" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <!-- 定义列 -->
            <DataGridTextColumn Header="列1" Binding="{Binding Property1}" />
            <DataGridTextColumn Header="列2" Binding="{Binding Property2}" />
            <!-- 添加更多列 -->
        </DataGrid.Columns>
    </DataGrid>
</Grid>

public class MyDataModel
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
    // 添加更多属性
}

public partial class MainWindow : Window
{
    public ObservableCollection<MyDataModel> DataList { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        DataList = new ObservableCollection<MyDataModel>();
        // 添加数据到DataList
        myDataGrid.ItemsSource = DataList;
    }
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    myDataGrid.Items.Refresh();
}
