Gridview验证

时间:2011-05-16 04:14:32

标签: c# javascript asp.net gridview

我正在使用Gridview并使用“项目模板”文本框。有5个文本框,我在点击添加行btn时动态添加新行。在那一行我添加了所有空文本框。现在我想验证btn上的文本框,然后点击下一步。

现在去做吗?

我使用了必需的字段验证,它首次显示文本框,但是当我添加一个新的行文本框时,它不会导致验证,我认为还有其他方法可以为动态添加的文本框进行验证。

如何验证我所有动态添加的文本框

我正在使用的网格视图..

您已在“下一步”按钮上使用了验证组的ValidationGroup="a",但尚未在“必填字段验证程序”上使用该验证组。但您已在电子邮件验证程序中使用它。

您必须与验证控件保持一致,并且是否对所有控件和按钮控件进行验证才能使其正常工作。

<asp:Button ID="btnNext" runat="server" ValidationGroup="a" CausesValidation="true" Text="Next" class="next btn" onclick="btnNext_Click"/>

我认为你应该开始一个新的页面并使用一个更小的案例场景进行测试,并让它首先运行。然后添加更多框。
