Silverlight4.0(8) 之 父窗体及子窗体变换

  加班加班还是加班 = =  真愁人,两个礼拜了基本上没怎么看Silverlight,感觉手都生了大脑都锈了...只好拿出之前的一个小例子写写了

  Silverlight中子窗体可以说解决了很多人在C#.Net中弹层(Div)的问题，在C#.Net中，想弹出一个子窗体要不就得用js要不就得用div,然后还要加以美工传值判断...等一系列繁杂的工作，而现在只要新建一个子窗体就可以解决了
  今天说我研究过的三种情况：简单弹窗,获得子窗体命令,三级弹窗

  1. 简单弹窗：点击按钮弹出子窗体，选择子窗体中的按钮关闭子窗体

  2. 获得子窗口命令：关闭子窗口的同时获得子窗口DialogResult的属性

  3. 三级弹窗：在弹出子窗口的基础上再弹出一个子窗口

  MainPage.xaml

  MainPage.xaml.cs

//弹出ChildWindow1子窗口
        private void hyperlinkButton0_Click(object sender, RoutedEventArgs e)
        {
            ChildWindow1 c1 = new ChildWindow1(); //实例化子窗口
            c1.Show();//打开子窗口
        }
        //弹出ChildWindow1子窗口并触发子窗口关闭事件
        private void hyperlinkButton1_Click(object sender, RoutedEventArgs e)
        {
            ChildWindow1 c2 = new ChildWindow1(); //实例化子窗口
            c2.Show(); //打开子窗口
            c2.Closed += new EventHandler(c2_Closed); //委托子窗口关闭事件
        }
        //子窗口关闭事件
        void c2_Closed(object sender, EventArgs e)
        {
            ChildWindow1 c2 = (ChildWindow1)sender;  //子窗口获得按钮事件
            string state = c2.DialogResult.ToString();//获得窗口关闭时DialogResult的属性
            MessageBox.Show(state);//输出该属性的值
        }
        //子窗口弹出事件
        private void hyperlinkButton2_Click(object sender, RoutedEventArgs e)
        {
            ChildWindow1 c3 = new ChildWindow1(); //实例化子窗口
            c3.Show();//打开子窗口
        }

  ChildWindow1.xaml.cs

//弹出ChildWindow1子窗口
        private void hyperlinkButton0_Click(object sender, RoutedEventArgs e)
        {
            ChildWindow1 c1 = new ChildWindow1(); //实例化子窗口
            c1.Show();//打开子窗口
        }
        //弹出ChildWindow1子窗口并触发子窗口关闭事件
        private void hyperlinkButton1_Click(object sender, RoutedEventArgs e)
        {
            ChildWindow1 c2 = new ChildWindow1(); //实例化子窗口
            c2.Show(); //打开子窗口

            c3.Show();//打开子窗口
        }

 ChildWindow2.xaml

<Grid x:Name="LayoutRoot" Margin="2">
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

        <Button x:Name="CancelButton" Content="Cancel" Click="CancelButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Margin="0,12,0,0" Grid.Row="1" />
        <Button x:Name="OKButton" Content="OK" Click="OKButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Margin="0,12,79,0" Grid.Row="1" />
    </Grid>

 

 

 这里说一下子窗体的DialogResult属性

DialogResult属性在子窗体打开时其值是null,当DialogResult属性值发生改变时(true/false)子窗体才会关闭，否则子窗体将一直停留在浏览器上

其他的我注释写的已经很清楚了,本身子窗体与父窗体的交换就不是难点，只不过之前研究过就写上了...
