重新想象 Windows 8 Store Apps (7) - 控件之布局控件: Canvas, Grid, StackPanel, VirtualizingStackPanel, WrapGrid, VariableSizedWrapGrid

作者：webabcd


介绍
重新想象 Windows 8 Store Apps 之布局控件

• Canvas - 绝对定位式布局
• Grid - 网格式布局
• StackPanel - 流式布局
• VirtualizingStackPanel - 仅能用于 ItemsControl
• WrapGrid - 仅能用于 ItemsControl
• VariableSizedWrapGrid - 用于 Wrap 子元素集合

示例
1、Canvas 的 Demo
CanvasDemo.xaml

<Page

    x:Class="XamlDemo.Controls.Layout.CanvasDemo"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="using:XamlDemo.Controls.Layout"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d">



    <Grid Background="Transparent">

        <!--

            Canvas - 绝对定位式布局

                Canvas.Left - 与上一层 Canvas 的 Y轴 间的距离，左上角为原点

                Canvas.Top - 与上一层 Canvas 的 X轴 间的距离，左上角为原点

                Canvas.ZIndex - 用于设置任意控件的 z-index 值

        

            注：Canvas 基于坐标定位，其不会因为自身的大小而限制子元素的大小

        -->

        <Canvas HorizontalAlignment="Left" VerticalAlignment="Top" Background="Red" Width="100" Height="100" Margin="120 0 0 0">



            <Canvas Background="Green" Width="200" Height="200" Canvas.Left="120" Canvas.Top="120" >

                <TextBlock Text="TextBlock" Canvas.Top="20" />

            </Canvas>



        </Canvas>

    </Grid>

</Page>

2、Grid 的 Demo
GridDemo.xaml

<Page

    x:Class="XamlDemo.Controls.Layout.GridDemo"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="using:XamlDemo.Controls.Layout"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d">



    <Grid Background="Transparent">

        <!--

            Grid - 网格式布局

                Grid.RowDefinitions - 用于定义 Grid 中的行

                Grid.ColumnDefinitions - 用于定义 Grid 中的列

                Width - 宽度

                MinWidth - 最小宽度

                MaxWidth - 最大宽度

                Height - 高度

                MinHeight - 最小高度

                MaxHeight - 最大高度

                Grid.Row - 控件所在的 Grid 的行的索引

                Grid.Column - 控件所在的 Grid 的列的索引

                Grid.RowSpan - 合并行。 控件所在行，以及控件所在行之后的需要连续合并的行的总行数

                Grid.ColumnSpan - 合并列。 控件所在列，以及控件所在列之后的需要连续合并的列的总列数

                Canvas.ZIndex - 用于设置任意控件的 z-index 值

                        

            Width 和 Height 的可用值如下：

            1、Auto - 自动设置为一个合适的值。默认值

            2、Pixel - 像素值

            3、* - 比例值。如 * 就是全部，2* 和 8* 就是分别占 20% 和 80%

        -->

        <Grid Background="Blue" Width="300" Height="300" Canvas.ZIndex="100">

            <Grid.RowDefinitions>

                <RowDefinition Height="50" />

                <RowDefinition Height="3*" />

                <RowDefinition Height="7*" />

                <RowDefinition Height="*" MinHeight="50" MaxHeight="100" />

                <RowDefinition Height="Auto" />

            </Grid.RowDefinitions>

            <Grid.ColumnDefinitions>

                <ColumnDefinition />

                <ColumnDefinition />

                <ColumnDefinition />

            </Grid.ColumnDefinitions>



            <TextBox Grid.Row="0" Grid.Column="0" Background="red" Text="webabcd" />

            <TextBox Grid.Row="0" Grid.Column="1" Background="red" Text="webabcd" Grid.ColumnSpan="2" HorizontalAlignment="Center" />

            <TextBox Grid.Row="1" Grid.Column="0" Background="red" Text="webabcd" />

            <TextBox Grid.Row="1" Grid.Column="1" Background="red" Text="webabcd" Grid.ColumnSpan="2" HorizontalAlignment="Center" />

            <TextBox Grid.Row="2" Grid.Column="0" Background="red" Text="webabcd" />

            <TextBox Grid.Row="2" Grid.Column="1" Background="red" Text="webabcd" Grid.RowSpan="2" VerticalAlignment="Bottom" />

            <TextBox Grid.Row="2" Grid.Column="2" Background="red" Text="webabcd" />

            <TextBox Grid.Row="3" Grid.Column="2" Background="red" Text="webabcd" />

            <TextBox Grid.Row="4" Grid.Column="2" Background="red" Text="webabcd" />

        </Grid>



        

        <!--    

            Canvas.ZIndex - 用于设置任意控件的 z-index 值

        

            说明：

            1、Grid 的 HorizontalAlignment 属性和 VerticalAlignment 属性的默认值均是 Stretch

            2、在 Grid 内的所有子元素均需要通过 Margin 属性进行相对定位

        -->

        <Rectangle Margin="10 50 100 150" Fill="Green" Canvas.ZIndex="10" />
