我正在使用Gridview并使用Item Template文本框。有5个文本框，我点击添加行btn动态地添加一个新行。在那一行中，我添加了所有空的文本框。现在我想在btn上验证该文本框，然后单击下一步。Gridview验证
现在要做？
我使用了必需的字段验证其第一次显示文本框的工作，但是当我添加一个新的行文本框它不会导致验证，我认为有一些其他方式来验证动态添加文本框。
我怎么能确认我的所有动态添加文本框里面我是用
网格视图..

你有什么代码？ – soandos 2011-05-16 04:16:39
@Ansari;验证问题是在运行时添加控件的时候？否则，它的工作完美？请发布您的完整代码，以便我们能够确定您的问题。 – 2011-05-16 04:27:32
