Silverlight2 控件布局（笔记）

使用一个嵌套的 Canvas 创建了蓝色矩形框包围下的红色矩形效果。
<Border Background="Coral" Width="300" Padding="10" CornerRadius="20">
    <TextBlock FontSize="16">Text Surrounded by a Border</TextBlock>
</Border>

StackPanel垂直排列

<StackPanel Margin="20">
    <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>

水平排列
<StackPanel Orientation="Horizontal" Margin="20">
    <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>

Grid 是 Silverlight 提供的灵活程度最高、功能最为强大的容器对象。Grid 定义一个由列和行组成的灵活的网格区域。Grid 的列和行分别是使用 ColumnDefinition 和 RowDefinition 定义的。默认情况下，网格的子级放置在第一行和第一列中。可以通过设置 Grid..::.Column 和 Grid..::.Row 附加属性，在 Grid 的特定单元格中定位对象。

<Grid x:Name="LayoutRoot" Background="Coral" Width="300" Height="100" ShowGridLines="True">
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>
    <TextBlock Grid.Column="0" Grid.Row="0" Text="First Name" HorizontalAlignment="Center" VerticalAlignment="Center" />
    <TextBlock Grid.Column="0" Grid.Row="1" Text="Last Name" HorizontalAlignment="Center" VerticalAlignment="Center" />
    <TextBox Grid.Column="1" Grid.Row="0" Margin="15,10,15,10" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="15,10,15,10" />

</Grid>

最后作了一个练习

<Grid x:Name="LayoutRoot"  Width="800" Height="600"  ShowGridLines="True">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
            <ColumnDefinition  />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="60"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
            <RowDefinition Height="30"/>
        </Grid.RowDefinitions>
