我真的需要一些帮助。我试图将我的GridView中的链接按钮连接到ModalPopupExtender，但没有运气。基本上我有一个GridView，它列出了数据库中所有用户的信息，我将用户名设为linkbutton。单击用户名时，应显示modalpopup，您应该能够编辑用户并更新数据库。我也有一个添加按钮。当您单击该按钮时，应显示相同的modalpopup，您可以向数据库添加新用户。 以下是我的aspx和代码。到目前为止，我有两个主要问题。 （1）OnClick甚至不会一直被解雇。 （2）单击用户名linkbutton时，modalpopup不会显示。 如果有人能帮助我，我真的很感激。
这是我的aspx页面：

答案 0 :(得分：1)
要编写的代码太多，但您需要在LinkButton期间将每个ModalPopupExtender与GridView.RowDataBound相关联。
您真正的问题是访问要编辑的行数据。如果这是真正的目标，请参阅下面的示例，然后您可以将其与ModalPopupExtender。

我建议您使用ListView，模板（EditItemTemplate ...等）更容易使用。
