移动先行之谁主沉浮? 带着你的Net飞奔吧! 链接======>(点)

 

一、布局类控件
Grid、StackPanel、Canvas、 VariableSizedWrapGrid
1.布局控件 - Grid
  网格控件,网格布局;
  相当于 HTML 中的 Table 标签;
  但是注意 Table 更重要的是展示数据,而 Grid 则是专门为布局所生;
 
  属性标记
    Grid.RowDefinitions:行定义,元素类型 RowDefinition,必要属性 Height
    Grid.ColumnDefinitions:列定义,元素类型 ColumnDefinition,必要属性 Width
    Width 和 Height属性单位为像素,有两个特殊值“*”、“auto”
   
  常用附加属性
    Grid.Row:定义当前元素所出现的行号
    Grid.Column :定义当前元素所出现的列号
    Grid.RowSpan :定义当前元素所跨的行数
    Grid.ColumnSpan:定义当前元素所跨的列数
    
  1.案例:定义一个3行2列的表格,在其中放元素
  
  效果:
  
 
  2.综合案例:计算器页面模仿
  创建一个基本页(WP统一样式)
  
  生成的页面,代码放在下面grid里面
  
  布局分析:(对空格和=来说,实现的话就要合并单元格)
  
  定义部分(上面的样式先忽略,和css有点相似,不会用的话在每个控件后面打属性值就可以了,后面会讲)
  
  下面是ui部分:(注意:row从0开始,column也是从0开始

完整代码
  补充点:* 和 auto (举一个简单例子)
  
  
 
2.布局控件 - StackPanel
  类似于 HTML 中的 DIV 标签;
  用于将子元素沿 垂直/水平(Orientation)方向排布;
  如果子内容超出面板,则会超出面板边界,但视觉上会被截断。
 
  案例
  
 我们平时对齐方式是 HorizontalAlignment和VerticalAlignment,Orientation是StackPanel等的排布方式,不要搞混淆
   
 
3.布局控件 - Canvas(画布)
  Canvas 中的每一个元素就相当于在 HTML 中设置了 “position:absolute”;
  可以通过 Canvas.Left、Canvas.Top 设置定位位置;
  可以使用 Canvas.ZIndex 附加属性明确指定分层
 
  案例:(图形化设置背景用 fill 来填充)
  
  效果:
  
 
 <!--
    可以把他理解为绝对定位
    Top 距离顶端
    Left 距离左边
    ZIndex Z坐标轴
    -->
    <Canvas>
        <Button Background="Beige" Width="100" Height="100"></Button>
        <Button Background="Blue" Canvas.Left="50" Canvas.Top="50" Width="100" Height="100"></Button>
        <Button Background="Chartreuse" Canvas.ZIndex="1" Canvas.Left="100"  Canvas.Top="100" Width="100" Height="100"></Button>
        <Button Background="Red" Canvas.Left="150"  Canvas.Top="150" Width="100" Height="100"></Button>

        <!--图形系列(Canvas里面用的比较多):背景用Fill来填充-->

        <!--正方形-->
        <Rectangle Width="300" Height="300" Fill="Yellow" Opacity="0.7" Canvas.ZIndex="-1"></Rectangle>

        <!--矩形-->
        <Rectangle Width="300" Height="200" Fill="Yellow" Opacity="0.7" Canvas.Top="50" Canvas.ZIndex="-1"></Rectangle>

        <!--圆形-->
        <Ellipse Width="100" Height="100" Fill="Pink" Opacity="0.9" Canvas.ZIndex="9" Canvas.Left="120" Canvas.Top="120"></Ellipse>

        <!--椭圆-->
        <Ellipse Width="100" Height="50" Fill="Black" Opacity="0.1" Canvas.ZIndex="9" Canvas.Left="120" Canvas.Top="150"></Ellipse>
    </Canvas>

4.布局控件 - VariableSizedWrapGrid

  元素以行或列排列,当达到 MaximumRowsOrColumns 值会时会自动换行至新行或新列。
  由 Orientation 属性指定是按行还是列排列元素。
  通过使用附加属性 VariableSizedWrapGrid.RowSpan 和 VariableSizedWrapGrid.ColumnSpan,内容可跨越多行和多列。
  根据 ItemHeight 和 ItemWidth 属性的指定设置元素大小。
  不需要定义行和列的 Grid
 
  案例:(磁贴和非正常布局使用,一般不怎么用)
  
  效果:
   
<Page
    x:Class="_05.AllControls._1.Layout._VariableSizedWrapGrid"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

    <VariableSizedWrapGrid Orientation="Horizontal" MaximumRowsOrColumns="3">
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle VariableSizedWrapGrid.ColumnSpan="2" Fill="Yellow" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle VariableSizedWrapGrid.RowSpan="2" Fill="Yellow" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
        <Rectangle Fill="Red" Width="100" Height="100"></Rectangle>
    </VariableSizedWrapGrid>
