本文主要是介绍WPF自适应、 简单适应性布局，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
了解bootstrap的人知道，它的栅格系统或者说网格系统。将屏幕宽度均为12部分。模拟这种网格，可以快速实现WPF的布局自适应。
定义全局Grid。在按自己的排版布置，设置行，设置列。分别设置各自的比例。比如：我设置行1:2:3:4。设置列1:2:2:3:1。
然后布局中的每个控件设置对应的Grid行，Grid列，以及占的行数或者列数。
代码如下：
<Grid><Grid.RowDefinitions><RowDefinition Height="*"></RowDefinition><RowDefinition Height="2*"></RowDefinition><RowDefinition Height="3*"></RowDefinition><RowDefinition Height="*"></RowDefinition></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="*"></ColumnDefinition><ColumnDefinition Width="2*"></ColumnDefinition><ColumnDefinition Width="2*"></ColumnDefinition><ColumnDefinition Width="3*"></ColumnDefinition><ColumnDefinition Width="*"></ColumnDefinition></Grid.ColumnDefinitions><Button Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Content="按钮1"></Button><Button Grid.Row="0" Grid.Column="3" Content="按钮2"></Button><Button Grid.Row="1" Grid.Column="0" Content="按钮3"></Button><Button Grid.Row="2" Grid.Column="2" Content="按钮4"></Button><Button Grid.Row="2" Grid.Column="1" Content="按钮5"></Button><Button Grid.Row="3" Grid.Column="4" Content="按钮6"></Button><Button Grid.Row="3" Grid.Column="2" Content="按钮7"></Button></Grid>
不需要设置任何高宽。界面显示如下：
加上DevExpress，再稍微布置一下，所有控件没有设置任何高度和宽度：
