I cannot get DataGrid binding to work in the example bellow.Any clues on what's going on ?

            public int age { get; set; }
            public String Name { get; set; }

            public Person(int age, String Name)
            {
                this.age = age;
                this.Name = Name;
            }
        }

        public class MegaObject
        {
            public IList<Person> persons { get; set; }
            public MegaObject()
            {
                persons = new List<Person>();
                persons.Add(new Person(11, "A"));
                persons.Add(new Person(12, "B"));
                persons.Add(new Person(13, "C"));
            }
        }


        public Window1()
        {
            InitializeComponent();
            MegaObject myobject= new MegaObject();
            DataContext = myobject;
        }
    }
}


<Grid>
    <my:DataGrid
                    Name="dataGrid"

                 >
        <my:DataGrid.Columns>

            <my:DataGridTextColumn  Binding="{Binding Path=age, Mode=TwoWay}" >
            </my:DataGridTextColumn>

            <my:DataGridTextColumn Binding="{Binding Path=Name, Mode=TwoWay}" >
            </my:DataGridTextColumn>

        </my:DataGrid.Columns>


    </my:DataGrid>

</Grid>

推荐答案

ItemsSource绑定需要将Path(而非Source)设置为 persons .简单地将其表示为 {Binding person} 就可以解决问题(Path是标记中的默认属性)或显式地 {Binding Path = persons} .DataContext始终是继承的.

The ItemsSource binding needs to have Path set, not Source, to persons. Simply putting it as {Binding persons} would do the trick (Path is the default property in markup) or explicitly {Binding Path=persons}. The DataContext is always inherited.
