DotNetbar 中DataGridViewX实现全选的方法
先看效果吧，第一张图片是全选的时候获取到“随机数值”列的结果
下面这张是选择了部分行获取的选中行的第二列的结果
下面来说说他的实现过程。我主要还是参照
http://www.cnblogs.com/wuhuacong/archive/2011/12/30/2307600.html
实现的。
首先你要确保你安装了DotNetBar控件，如果没有安装就要到http://www.devcomponents.com/dotnetbar/ 网站下载安装winform版本的即可。
安装完毕之后，打开vs就可以看到相应的控件
如果没有出现对应的控件，则需要手工添加控件即可。
然后就会新建windows窗体应用程序，在工具箱中找到DataGridViewX 控件，拖动到窗体上，然后添加列并设置属性：
需要特别注意的是需要填写属性“Name”、“DataPropertyName”、“ColumnType”。这三个属性分别对应着列的名称、绑定的数据列、列的类型。当然我们还需要设置datagridview的其他属性，如列标题居中，自适应窗体等属性。
接下类我们就是要添加checkbox列，其实也就是第一列，主要是改变列的显示方式。

在上面的红色标注部分是针对dotnetbat的，对于winform 中控件datagridview而言就不一样了。

}
在上述代码中，我们只需要把数据源部分改变成list<>即可。
