所以我有这两个Gridview。名为'GridView1'的第一个正常工作，但第二个名为'Gridview2'，当我点击ButtonField从GridView ID列单元格中获取ID时，它获取正确的行索引，但是从错误的GridView，它从'GridView1'而不是'GridView2'获取它，其中功能ButtonField的代码在GridViewCommandEventArgs _RowCommand代码块中。我为我的生活无法弄清楚为什么它从第一个获得它，甚至e.CommandSource（.ID.toString（））说它来自GridView2，但我得到的列ID是从第一个。两个GridView是相同的，除了第二个有更多的ButtonFields并且是第一个的自定义视图，只有选定的ID显示在第二个GridView（GridView2）上。这是我的第一篇文章，非常感谢您的帮助。尝试搜索谷歌，但我的问题看起来如此具体，有点难以让它在网上找到更广泛。

但主要问题出在这个代码块中：

}
catch (Exception ex) { }
}
所以现在我必须找出一个更好的select语句，这样当自定义视图变为null时，它不会默认为第一个数据源，从外观上看它从不同的数据源获取相同的id。可能必须使用一些内联脚本，我仍然在接受意见，但这应该可以解决这个问题。
