Grid——网格布局,其中控件或容器需指定位置

StackPanel——堆叠面板,其中的控件水平布局、竖直布局

DockPanel——停靠面板,内部控件或容器可以放置在上、下、左、右

WrapPanel——可以看作是具有自动换行功能的StackPanel容器。窗体太小时,其末尾的控件会自动换行。像Java中的流布局

布局原则:先整体规划(Grid),再局部规划(Grid、StackPanel等)

如下图,Grid有5行3列,具体布局、控件查看文档大纲

 

xaml代码

<Window x:Class="DemoWPF61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="240" Width="350">
    <Grid >
        <!--行定义,5行-->
        <Grid.RowDefinitions>
            <RowDefinition Height="20"/>
            <RowDefinition Height="50"/>
            <RowDefinition Height="30"/>

        </Grid.RowDefinitions>
        <!--列定义,3列-->
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100"/>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="100"/>
        </Grid.ColumnDefinitions>
        <!--网格的2,3两列放置StackPanel-->
        <Grid Grid.Column="1" Grid.ColumnSpan="2">
            <!--水平布局,右对齐-->
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
                <!--方式1-->
                <Button Content="夕西行" Margin="5,0,0,0"/>
                <!--方式2-->
                <Button Margin="5,0,5,0">我的博客</Button>
            </StackPanel>
        </Grid>
        <!--网格的1列2行放置Image,默认居中对齐-->
        <Grid Grid.Column="0" Grid.Row="1">
            <Image Source="C:/Users/Jv/Desktop/lena512.tiff"/>
        </Grid>
        <!--网格的1~3列放置StackPanel-->
        <Grid Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="2">

            <StackPanel Orientation="Horizontal">
                <Button Margin="5,0,0,0">园子</Button>
                <Button Margin="5,0,0,0">新闻</Button>
                <Button Margin="5,0,0,0">博问</Button>
            </StackPanel>
        </Grid>
        <Grid Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="3">
            <!--左右居中,上下居中-->
            <Label Content="第4行,占三列" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        </Grid>
        <Grid Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="4">

            </StackPanel>
        </Grid>
    </Grid>
</Window>

【GroupBox】GroupBox内只能有一个元素,可用StackPanel承载多个控件

布局、控件如图所示 

  

<Window x:Class="DemoWPF61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DemoWPF61"
        mc:Ignorable="d"
        Title="MainWindow" Height="190" Width="200">
    <!--StackPanel纵向布局,纵向对齐方式:底对齐-->
    <StackPanel Orientation="Vertical" VerticalAlignment="Bottom" >
        <!--GroupBox内只能有一个元素,StackPanel来承载更多的控件-->
        <GroupBox Header="网站分类">
            <!--StackPanel内,纵向布局-->
            <StackPanel Orientation="Vertical">
                <Button Content=".NET技术(16)"/>
                <Button Content="编程语言(13)"/>
            </StackPanel>
        </GroupBox>
        <GroupBox Header="链接">
            <StackPanel Orientation="Vertical">
                <Button Content="反馈和建议"/>
                <Button Content="官方博客"/>
            </StackPanel>
        </GroupBox>
    </StackPanel>
</Window>

 【DockPanel】

  

<Window x:Class="DemoWPF61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DemoWPF61"
        mc:Ignorable="d"
        Title="MainWindow" Height="150" Width="230">
    <DockPanel>
        <StackPanel DockPanel.Dock="Top" >
            <Label Content="StackPanel停靠在DockPanel的上边"/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Bottom" Height="20">
        </StackPanel>
        <StackPanel DockPanel.Dock="Left" Width="30">
        </StackPanel>
        <StackPanel DockPanel.Dock="Right" Width="30"/>
        <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
            <Label Content=" 中间地带,是我的天下" />
        </StackPanel>
    </DockPanel>
</Window>

 【WrapPanel】可以看作是具有自动换行功能的StackPanel容器。默认从左到右排列。

   

左图最后一个Button的高度会变成最小尺寸。Orientation="Vertical"得到右图(默认水平布局)

<Window x:Class="DemoWPF61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DemoWPF61"
        mc:Ignorable="d"
        Title="MainWindow" Height="150" Width="209.199">
    <WrapPanel Margin="3">
        <Button Content="Top" VerticalAlignment="Top"/>
        <Button Content="Bottom" VerticalAlignment="Bottom"/>
        <Button Content="靠我撑大" MinHeight="40"/>
        <Button Content="Center" VerticalAlignment="Center"/>
        <Button Content="无对齐方式"/>
    </WrapPanel>
</Window>
