• 父窗体取得子窗体返回的值


    新建Silverlight子窗口
     

     
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Net;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Documents;
    using System.Windows.Input;
    using System.Windows.Media;
    using System.Windows.Media.Animation;
    using System.Windows.Shapes;

    namespace SilverlightXML
    {
        public partial class ChildWindow1 : ChildWindow
        {
            public string resultVal = "空";//子窗体中设置public
            public ChildWindow1()
            {
                InitializeComponent();
            }

            private void OKButton_Click(object sender, RoutedEventArgs e)
            {
                resultVal = txtInput.Text;//前台放个输入框
                txtInput.Text = "";
                this.DialogResult = true;
            }

            private void CancelButton_Click(object sender, RoutedEventArgs e)
            {
                this.DialogResult = false;
            }
        }
    }


    父窗体中调用

     
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Net;
    using System.Windows;
    using System.Windows.Controls;
    using System.Windows.Documents;
    using System.Windows.Input;
    using System.Windows.Media;
    using System.Windows.Media.Animation;
    using System.Windows.Shapes;

    namespace SilverlightXML
    {
        public partial class TestPage3 : UserControl
        {
            ChildWindow1 child = new ChildWindow1();
            public TestPage3()
            {
                InitializeComponent();
                child.Closed += new EventHandler(Child_Close);  //在父窗体注册子窗体的关闭事件
            }
            private void Child_Close(object sender, EventArgs e)
            {
                bool? result = child.DialogResult;

                if (result.HasValue && result.Value)
                {
                    MessageBox.Show("子窗体返回:" + child.resultVal);
                }
            }
            private void btnChild_Click(object sender, RoutedEventArgs e)
            {
                child.Show();
            }
        }
    }
