怎么作控件互动的效果？

Question

我有一个datagrid，一个文本框。

我想点击修改datagrid cell的同时，文本框显示修改的文本，该怎么做呢？

例如，我双击 datagrid cell，修改值从 100 到200，文本框也会同步显示 100 到200。

谢谢

你好,

下面是代码. TextBlock绑到第一个对象:
  public MainPage()
        {
            InitializeComponent();
            for (int i = 0; i < 10; i++)
            {

                Customer c = new Customer { age = i };
                array.Add(c);
            }

            this.DataGrid1.ItemsSource = array;
            this.testTextBlock.DataContext = array[0];
    
        }


 public class Customer : INotifyPropertyChanged
    {

        #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;

        private int _age;

        public int age
        {
            get { return _age; }
            set
            {
                _age = value;
                if (PropertyChanged != null)
                {
                    PropertyChanged(this, new PropertyChangedEventArgs("age"));
                }
            }
        }

        #endregion
    }


   <TextBlock x:Name="testTextBlock" Text="{Binding age}"></TextBlock>
            <data:DataGrid AutoGenerateColumns="False"  Width="500" Height="500" x:Name="DataGrid1">
                <data:DataGrid.Columns>
                    <data:DataGridTemplateColumn Width="80">
                        <data:DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding age}"></TextBlock>
                            </DataTemplate>
                        </data:DataGridTemplateColumn.CellTemplate>
                        <data:DataGridTemplateColumn.CellEditingTemplate>
                            <DataTemplate>
                                <TextBox Text="{Binding age, Mode=TwoWay}"></TextBox>
                            </DataTemplate>
                        </data:DataGridTemplateColumn.CellEditingTemplate>
                    </data:DataGridTemplateColumn>

                </data:DataGrid.Columns>
            </data:DataGrid>
