文本框的GridView验证内部 [英] TextBox inside GridView validation
本文介绍了文本框的GridView验证内部的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我的code：
<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>
当我点击下一步按钮所需的字段验证不会导致验证其没有显示任何错误，下页页重新定向。
when i am clicking next button required field validation is not causing validation and its not showing any error and page is re-directing on next page.
请帮我。
