Silverlight 3.0 弹出对话框

1.sliverlight3.0在添加新建项的时候 可以添加ChildWindow.xaml

 

ChildWindow.xaml.cs

public ChildWindow1()
      {
          InitializeComponent();
      }

public string param="no set";

   private void OKButton_Click(object sender, RoutedEventArgs e)
   {
       if (textBox1.Text.Trim()!="")
       {
           this.param = textBox1.Text;
       }
       this.DialogResult = true;
   }

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

调用页面：

private void button1_Click(object sender, RoutedEventArgs e)
      {
          ChildWindow1 cw = new ChildWindow1() { Width=300,Height=300};
          cw.Closed += new EventHandler(cw_Closed);
          cw.Show();
         // MessageBox.Show(cw.param);
      }

      void cw_Closed(object sender, EventArgs e)
      {
          ChildWindow1 cw = (ChildWindow1)sender;
          if (cw.DialogResult == true)
          {
              label1.Content = "Param:";
              label1.Content = label1.Content.ToString() + cw.param;
          }
      }

运行效果：
