GridView里面的TextBox验证
Roc*_*cky 0 .net regex asp.net validation gridview
这是我的代码:
<asp:TemplateField HeaderText="Email">
<ItemTemplate>
<asp:TextBox ID="txtEmail" runat="server" Text='<%# Eval("Email") %>' Width="88px" CausesValidation="True" />
<asp:RegularExpressionValidator runat="server" ErrorMessage="Enter a valid email id!" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" ControlToValidate="txtEmail" />
<asp:RequiredFieldValidator runat="server" ErrorMessage="*" ControlToValidate="txtEmail" />
</ItemTemplate>
</asp:TemplateField>
当我点击下一个按钮所需的字段验证不会导致验证,它没有显示任何错误,页面正在下一页重新定向.
请帮我.
验证组可能存在问题,您可以检查.
其次,您需要设置CausesValidation="true"按钮控件.
另外,您的电子邮件正则表达式也不正确.
\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* // yours
\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)* // correct one
请查看以下代码.
