我正在处理一些我以前没有处理过的新概念，所以我可能过于复杂了。
我有一个从 5 表连接填充的 GridView。每列代表联接中的 5 个表之一。我想要实现的功能是这样的：
- 用户选择自动生成的编辑链接按钮
- 用户编辑行中的一个或多个单元格
- 用户选择自动生成的更新链接按钮
- 参数被传递给更新受影响的表的存储过程。
我对如何进行有一些不确定性。如果我直接查询更新，我需要从另一列传递 ID、更改的文本和外键 ID。所以我的问题是如何让 GridView UpdateCommand 将整行的数据传递给存储的 Proc？我目前已经用一个额外的参数设置了存储过程，我用它来确定需要更新哪个表，但由于它可能是多个表，我认为这是错误的方法。这是我的 GV、DSN 和 SP。
