我有两个主控制页面和子窗口..有数据网格主网页上，点击编辑按钮，数据网格，我想说明在子窗口文本框的行项目..
通过使用cw.textBox1 = mainpage.selectitem的工作，但我想使用文本框的数据绑定..所以怎么办呢......我尝试和我的代码是...
MainPage.xaml.cs中

namespace textbind

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

            CItem cv = dataGrid1.SelectedItem as CItem;

        }

 

        private void button1_Click(object sender, RoutedEventArgs e)

        {

 

        

            Service1Client proxy = new Service1Client();

            proxy.GetItemsCompleted +=new EventHandler<getitemscompletedeventargs>(proxy_GetItemsCompleted);

            proxy.GetItemsAsync();

 

        }

        void proxy_GetItemsCompleted(object sender, GetItemsCompletedEventArgs e)

        {

            dataGrid1.ItemsSource = e.Result;

        }

        

        private void btnEdit_Click(object sender, RoutedEventArgs e)

        {

 



            CItem ci = dataGrid1.SelectedItem as CItem;

 

            ChildWindow1 cw = new ChildWindow1();

            Person p = new Person();

 



            p.SName = "fdfdF";

         

            cw.Show();

        }

    }

}

</getitemscompletedeventargs>
