Question

通过我的模式弹出式窗口进行编辑功能，感谢您的帮助。

简介.. 我有一个用户列表。在此之前。每次要编辑用户详细信息时，将打开另一个页面，进行编辑，保存并返回到用户表列表。

我想所谓的更新页面以使用模式弹出窗口，因为要编辑的详细信息不是很多，因此需要打开另一个页面。但是我从这里的同伴那里获得了一些建议，可以在stackOverflow ..中使用GridView。.这是我的尝试..我设法编辑和删除，但下拉列表不正确..它没有选择原始值。选择第一个下拉列表。.我在GridView1_RowEditing中遇到错误。

非常感谢您的帮助。谢谢

为什么可以使用gridview功能编辑行时为什么要出现模式弹出窗口。

您可以在示例链接下方签出，以在Gridview中实现行编辑。
