@H_
404_7@通过Tag
属性可以设置
自定义的数据:
@H_404_7@（1）借助LoadingRow事件，在初始化DataGrid过程中 使用GetCellContent方法，它可以到单元格内的控件。这时，你也就可以得到你点击的是哪一行了，你可以选择将适当的信息赋给该行的Button的Tag属性; 然后在单击button 按钮时，就可以对该信息进行读取和使用了：
@H_
404_7@（2）如果你不关心
在某一行，而很需要得到改行绑定的实体。那么，你可以在定义Button的时候，将Button的Tag
属性直接进行空绑定,可以将该该行绑定的实体对象赋值给Tag，那么在单击Button时，就可以直接使用该对象了。
@H_404_7@这样，点击的操作就很灵活了，也可以解决很多问题了。
