Question

我正在处理我之前没有处理过的一些新概念，所以我可能会使这个问题复杂化。

我有一个从5表连接填充的GridView。每列代表Join中的5个表中的一个。我想要实现的功能是：

用户选择自动生成的Edit LinkButton
用户编辑行中的一个或多个单元格
用户选择自动生成的Update LinkButton
Params传递给Stored Proc，用于更新受影响的表格。

关于如何继续，我有几个不确定因素。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？我目前已经设置了存储过程，并使用了一个额外的参数来确定哪个表需要更新，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。
