表单视图中验证控件的问题.净c#

本文关键字：问题 控件 视图 验证 表单 | 更新日期: 2023-09-27 17:54:41

我在formview中的验证控制有一些问题。我可以在formview控件中添加一个验证控件，它工作得很好，直到我试图使用validationgroups对它们进行分组。此外，如果我不输入一个值的程序仍然允许在数据库中添加它。有人能帮我指出程序中的问题或错误吗?这是我写的Insert语句。

<InsertItemTemplate>
                Book ID:
                <asp:TextBox ID="bookidTextBox" runat="server" Text='<%# Bind("bookid") %>' />
                <asp:RequiredFieldValidator ID="RequesFieldValidator1" runat="server" ErrorMessage="* Required" ControlToValidate="bookidTextBox" ValidationGroup="InsertBook">
                </asp:RequiredFieldValidator>
                <asp:RegularExpressionValidator ID="RegularExpressionValidator" runat="server" Display="Dynamic" ControlToValidate="bookidTextBox" ValidationExpression="^(['S's]{13,13})$" ErrorMessage="Value must be at least 13 characters long">
                </asp:RegularExpressionValidator>
                <br />

表单视图中验证控件的问题.净c#

您必须设置ValidationGroup="InsertBook"，因为您已将验证组设置为验证。

 <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert"
                    Text="Add" ValidationGroup="InsertBook" />
