WPF的几种布局方式_.NET_编程开发_程序员俱乐部

1、StackPanel:顾名思义 堆栈面板，通过Orientation属性设置子元素的布局排列方向为“Vertical”（垂直）和“Horizontal”（水平），不写其默认值为“Vertical”，当设置为“Vertical”时子元素会沿水平方向拉伸，反之设置为“Horizontal”时子元素会沿垂直方向拉伸。

1 <StackPanel>
2         <Button Content="button1"></Button>
3         <Button Content="button2"></Button>
4         <Button Content="button3"></Button>
5         <Button Content="button4"></Button>
6     </StackPanel>

效果图：

1 <StackPanel Orientation="Horizontal">
2         <Button Content="button1"></Button>
3         <Button Content="button2"></Button>
4         <Button Content="button3"></Button>
5         <Button Content="button4"></Button>
6     </StackPanel>

2、DockPanel：支持子元素停靠在面板的任意一条边上，通过附加属性Dock控制他们的停靠位置（Left、Top、Right、Bottom），填充空间按照“先到先得”的原则，最后一个加入面板的子元素将填满剩下的空间，如不想将最后加入面板的元素填满剩下的空间将属性LastChildFill值设为“False”，默认为“True”。

1  <DockPanel >
2         <Button Content="button1" DockPanel.Dock="Top" Background="Aqua"></Button>
3         <Button Content="button2" DockPanel.Dock="Left" Background="Blue"></Button>
4         <Button Content="button3" DockPanel.Dock="Bottom" Background="Crimson"></Button>
5         <Button Content="button4" DockPanel.Dock="Right" Background="Gold"></Button>
6         <Button Content="button5" Background="GreenYellow"></Button>
7     </DockPanel>

效果图：

1 <DockPanel LastChildFill="False">
2         <Button Content="button1" DockPanel.Dock="Top" Background="Aqua"></Button>
3         <Button Content="button2" DockPanel.Dock="Left" Background="Blue"></Button>
4         <Button Content="button3" DockPanel.Dock="Bottom" Background="Crimson"></Button>
5         <Button Content="button4" DockPanel.Dock="Right" Background="Gold"></Button>
6         <Button Content="button5" Background="GreenYellow"></Button>
7     </DockPanel>

3、WrapPanel：可换行面板与StackPanel相似，通过Orientation属性设置子元素的排列顺序，从左至右按顺序位置定位子元素，当前行无法放下元素时断开至下一行，或者排序按照从上至下或从右至左的顺序进行，通过ItemHeight可以设置当前面板中所有子元素的高度，当然也有ItemWidth设置所有子元素的宽度。

 <WrapPanel Orientation="Horizontal" ItemHeight="50" ItemWidth="80" >
        <Button Content="button1" Background="Aqua"></Button>
        <Button Content="button2" Background="Blue"></Button>
        <Button Content="button3" Background="Crimson"></Button>
        <Button Content="button4" Background="Gold"></Button>
        <Button Content="button5" Background="GreenYellow"></Button>
        <Button Content="button1" Background="Aqua"></Button>
        <Button Content="button2" Background="Blue"></Button>
        <Button Content="button3" Background="Crimson"></Button>
        <Button Content="button4" Background="Gold"></Button>
        <Button Content="button5" Background="GreenYellow"></Button>
        <Button Content="button1" Background="Aqua"></Button>
        <Button Content="button2" Background="Blue"></Button>
        <Button Content="button3" Background="Crimson"></Button>
        <Button Content="button4" Background="Gold"></Button>
        <Button Content="button5" Background="GreenYellow"></Button>
        
    </WrapPanel>
