Question

我只是想让我的gridview可编辑，这将填充数据库中的数据。当我的程序启动时，它将连接到数据库并使用数据填充gridview。现在我想编辑其中的数据。我不知道我在做什么错误，因为我在视觉工作室的设计视图中遇到了这个错误ERROR:- Error creating control - GridView1. The server tag is not well formed.

看看标签并告诉我我犯错的地方。

Answer 1

在将数据绑定到文本框时，您可以写 text =“＆lt;％＃Eval（”Description“）％＆gt;”而是写入text = '＆lt;％＃Eval（“Description “）％＆GT;'

而不是“”写''。

所有TextBox都相同。

创建控件时出错 - GridView1。服务器标签格式不正确
