wpf之布局控件

Grid

比如：

<UserControl x:Class="MyWpf.MyGrid"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid>
        <Grid.RowDefinitions>
            <!--指定宽高，剩余的会自动占满-->
            <RowDefinition Height="90"></RowDefinition>
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100"></ColumnDefinition>
            <ColumnDefinition></ColumnDefinition>
        </Grid.ColumnDefinitions>
        <!--可以指定行列-->
        <Border Background="Red" Grid.Row="0"></Border>
        <Border Background="Blue" Grid.Row="1"></Border>
        <Border Background="SandyBrown" Grid.Column="1" Grid.Row="0"></Border>
        <Border Background="RosyBrown" Grid.Column="1" Grid.Row="1"></Border>
    </Grid> 
</UserControl>

结果：

StackPanel

StackPanel是以堆叠的方式显示其中的控件

1、可以使用Orientation属性更改堆叠的顺序分为水平方向（Orientation="Horizontal"）和竖直方向（Orientation="Vertical"），以保证要实现的效果。

代码：

<UserControl x:Class="MyWpf.MyStackPanel"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="350" d:DesignWidth="500">
    <Grid>
        <StackPanel> 
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
        </StackPanel>
    </Grid>
</UserControl>

结果：

可以看到默认是垂直排序的，改动代码：

<UserControl x:Class="MyWpf.MyStackPanel"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="350" d:DesignWidth="500">
    <Grid>
        <StackPanel Orientation="Horizontal"> 
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
        </StackPanel>
    </Grid>
</UserControl>

结果：

但是这个也存在问题，那就是超出界限的部分就被截取了。

WrapPanel

WrapPanel布局控件默认水平摆放，但是会自动换行

<UserControl x:Class="MyWpf.MyStackPanel"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="350" d:DesignWidth="500">
    <Grid>
        
        <WrapPanel>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button> 
        </WrapPanel> 
        
    </Grid>
</UserControl>

结果：

下面改成垂直摆放，超出界限就会自动换列：

<UserControl x:Class="MyWpf.MyStackPanel"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="350" d:DesignWidth="500">
    <Grid>
        <WrapPanel Orientation="Vertical">
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button>
            <Button Width="80" Height="60"></Button> 
        </WrapPanel>
            
        
        
    </Grid>
</UserControl>

结果：

DockPanel

<UserControl x:Class="MyWpf.MyStackPanel"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:MyWpf"
             mc:Ignorable="d" 
             d:DesignHeight="350" d:DesignWidth="500">
    <Grid>

        <DockPanel LastChildFill="False"> 
            <Button DockPanel.Dock="Bottom" Width="80" Height="60"></Button>
            <Button DockPanel.Dock="Top" Width="80" Height="60"></Button>
            <Button DockPanel.Dock="Left" Width="80" Height="60"></Button>
            <Button DockPanel.Dock="Right" Width="80" Height="60"></Button>

        </DockPanel>
        
        
    </Grid>
</UserControl>
