WPF动态添加按钮并相应事件。

上code：

点击(此处)折叠或打开

1. <Window x:Class="WpfApplication1.MainWindow"
   
2.         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   
3.         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
   
4.         Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
   
5.     <Grid>
   
6.         <Canvas Name="abc" Margin="0,57,0,0">
   
7.             <Button Canvas.Left="400" Canvas.Top="207" Content="Button" Height="30" Name="Button2" Width="85" Click="btn_click"/>
   
8.         </Canvas>
   
9.     </Grid>
   
10. </Window>

上面是布局的时候加了个按钮，下面的代码中会加入个程序中创建的。
