使用Grid做页面布局笔记

没有使用wpf做过精细的页面布局，学习了一下。

WPF中页面布局的控件很多，经过这段时间的学习发现：想要出特定的效果必须了解控件的使用布局和常用属性设置。

首先我说明我想要的效果以及实现方法：

效果如下图

目标是实现拖拽中间的青色GridSplitter能够任意调整上下控件的面积。

这里需要记录的几点：

1、DockPanel 是用来规则的按顺序拜访控件的，目标是控件可以停靠在四角，最后一个控件可以Fill剩余的空间

 

// Todo: 最近较忙 稍后补充……

 

经过学习后发现很多种方法都可以，现在贴出我测试的一种（把绑定的后台代码删除就能看到效果，VS2015）：

    <DockPanel Name="dockPanel1">
        <WrapPanel Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="4" HorizontalAlignment="Stretch"
                   VerticalAlignment="Stretch" Background="Beige" DockPanel.Dock="Top" Height="40" Margin="2">
            <Button Command="{Binding CopyCmd}" Height="30" Content="复制" Margin="6" />
            <Label HorizontalContentAlignment="Left" VerticalContentAlignment="Center" HorizontalAlignment="Stretch"
                   VerticalAlignment="Stretch"
                   Background="Green" Margin="10" Width="200">

        </WrapPanel>
