请注意，“我的日期”列的数据类型为nchar（8）。现在，我想修改上面发布的asp.net代码，以接受此日期参数。我不知道如何编辑代码，因为我是非常新的asp.net并且还在学习

FYI startdate和enddate列不在gridview中。请更正您的代码。如何在gridview中添加它们？从何处获取startdate和enddate参数的值？？？有文本框吗？如果是startdate，则sp只返回一个列的日期，那么enddate在哪里？？？是的，我有一个.html文件，其中有两个文本框名为startdate和enddate。我添加了mosaklevN给出的代码，但当我在文本框中输入日期并提交时，网页

GridView示例：Execute StoredProcess

中只显示这一行，它不显示表中的数据。我编辑两个文本框中的代码，请看下面。谢谢moskalevN，但现在我得到了错误，因为我在上面添加了你的新代码后，只需添加两个名为textboxStartDate和textboxEndDate的文本框。我相信你可以
