[Winodows Phone 7控件详解]容器控件

在Windows Phone7中存在着多个容器控件，这些控件主要是用来界面的布局设置，以及包容多个控件时的布局设置。

一.Grid控件：主要用于界面的布局，这个和web page里的很相似，可以通过网格布置规划界面，也可以嵌套使用。

<Grid x:Name="LayoutRoot" Background="#DCDCDC" Width="400" Height="300" ShowGridLines="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="250" />
        <ColumnDefinition Width="150" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="2*" />
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" FontWeight="Bold" Text="Contoso Corporation" HorizontalAlignment="Center" VerticalAlignment="Center" />
    <Grid x:Name="FormLayoutGrid" Grid.Row="1" Grid.Column="0" ShowGridLines="True">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <TextBlock Grid.Row="0" Grid.Column="0" Text="First Name" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="0" Grid.Column="1" Margin="10" />
        <TextBlock Grid.Row="1" Grid.Column="0" Text="Last Name" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="1" Grid.Column="1" Margin="10" />
        <TextBlock Grid.Row="2" Grid.Column="0" Text="Address" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
        <TextBox Grid.Row="2" Grid.Column="1" Margin="10" />

    </Grid>
 </Grid>

二.Canvas控件：  容器、布局控件，主要是用绝对坐标来定位子控件。对于游戏开发来说用处很大。

<Canvas x:Name="C1"  Grid.Row="2">
  <CheckBox x:Name="CheckBox3" Content="CheckBox3" Canvas.Top="50" Canvas.Left="100" Canvas.ZIndex="1" />
</Canvas>

也可以使用代码来控制

Canvas.SetLeft();
Canvas.SetTop();
Canvas.SetZIndex();//控制子控件在Z轴上的顺序。

三.StackPanel控件：容器、布局控件，主要用来多个子控件的纵向、横向的布局控制。

<StackPanel x:Name="stackPanel1" Margin="20" Orientation="Vertical" >
   <Rectangle Fill="Red" Width="50" Height="50" Margin="5" />
   <Rectangle Fill="Blue" Width="50" Height="50" Margin="5" />
   <Rectangle Fill="Green" Width="50" Height="50" Margin="5" />
   <Rectangle Fill="Purple" Width="50" Height="50" Margin="5" />
</StackPanel>

可以使用下面的方法向上面的StackPanel中动态插入一个Rectangle

private void button1_Click(object sender, RoutedEventArgs e)
{
  Rectangle rect = new Rectangle() { Fill = new SolidColorBrush(Colors.Yellow),Width=50,Height=50};
  stackPanel1.Children.Insert(2, rect);
}

四.Border控件： 用于包容一个控件并为其绘制边框，并且通过参数设置可以产生多种不同的边框效果。（不太应该算为容器控件，但是又觉得放在别的类里又不是很合适。Jake Lin 和李振都这么分，我采纳了这个观点）

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,12">
  <Border Background="Coral" Width="300"  Height="40" Padding="10" CornerRadius="20">
    <TextBlock FontSize="16">Text Surrounded by a Border</TextBlock>
  </Border>
  <Border  x:Name="b1" Width="200" Height="200"  Background="Gold" BorderBrush="Aquamarine" BorderThickness="10, 5, 20, 40"  Margin="119,346,137,49"  CornerRadius="25, 200, 10, 15" >
    <TextBox Height="67" Name="textBox1" Text="Test Border" Background="Gold"  Foreground="White" BorderBrush="Gold" Width="170"  VerticalAlignment="Bottom"/>
  </Border>
</Grid>

BorderThickness：边框宽度，设置不同的值使四个边产生不同的宽度。

CornerRadius：边角半径，设置不同的值四个边角产生不同的弧度。

五.PopUp控件：严格来讲这个不应该算作容器控件，但是它可以把包含在其中的控件显示在当前页的最前面，可以被打开和关闭。可以用来制作自定义的MessageBox、WaitingBox等。

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,36,132">
            <Image  Source="Images/1.jpg" Height="426" HorizontalAlignment="Left" Margin="25,25,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="386" />
            <!-- 这个容器可以被打开和关闭 -->
            <Popup IsOpen="True"     HorizontalAlignment="Left" Margin="92,106,0,0" Name="popup1" VerticalAlignment="Top" Height="250" Width="250" >
                <Canvas Width="250" Height="250" Background="Red" VerticalAlignment="Center" HorizontalAlignment="Center">
                    <TextBlock Margin="30,120,0,0" Text="我在当前页面的上层"/>
                </Canvas>
            </Popup>
        </Grid>
        <Button Content="打开" Grid.Row="1" Height="72" HorizontalAlignment="Left" Margin="64,523,0,0" Name="btnOpen" VerticalAlignment="Top" Width="160" Click="btnOpen_Click" />
        <Button Content="关闭" Height="72" HorizontalAlignment="Left" Margin="230,523,0,0" Name="btnClose" VerticalAlignment="Top" Width="160" Grid.Row="1" Click="btnClose_Click" />
    </Grid>

六.ScrollView:  滚动查看器控件，也算是一个容器控件，它可以用来拖动显示其所包含的控件的内容。

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Canvas>
            <!-- A large TextBlock. -->
            <!-- A large TextBlock. -->
            <TextBlock   Canvas.Top="60" Canvas.Left="-50" Width="400" TextWrapping="Wrap" 
  Text="I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted, too, with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news, With many cheerful facts about the square of the hypotenuse." Margin="78,0,78,201" />

            <!-- The same large TextBlock, wrapped in a ScrollViewer. -->
            <!-- It can be scrolled in either direction, since VerticalScrollBarVisibility -->
            <!-- has a default value of Visible. -->
            
<ScrollViewer BorderBrush="Green" BorderThickness="5"  Height="200" Width="300" HorizontalScrollBarVisibility="Auto" Canvas.Top="400" Canvas.Left="80">
                <TextBlock  Width="300" TextWrapping="Wrap" 
    Text="I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted, too, with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news, With many cheerful facts about the square of the hypotenuse." />
            </ScrollViewer>
            </Canvas>
        </Grid>
