Question

有没有办法在ASP changepassword控件中自定义文本框？

<asp:ChangePassword id="myChangePassword" newpasswordregularexpressionerrormessage="Error: Your password must be at least 5 characters long, and contain at least one number and one special character." 
runat="server"  OnChangingPassword="ChangingPassword" 
OnChangedPassword="ChangedPassword" OnCancelButtonClick="CancelClick"></asp:ChangePassword>

例如，我希望顶部字段显示当前密码而不仅仅是密码，这可能吗？

谢谢！

是的，这是可能的。与许多asp.net控件一样，控件中有一个标签，允许您自定义字段。

看看这个：

<asp:ChangePassword ID="ChangePassword1" runat="server" 
        ContinueDestinationPageUrl="~/Users/UserProfile.aspx" style="margin-right: 2px" 
        Width="450px">
        <ChangePasswordTemplate>
            <table cellpadding="1" cellspacing="0" style="border-collapse:collapse;">
                <tr>
                    <td>
                        <table cellpadding="0">
                            <tr>
                                <td align="center" colspan="2">
                                    Change Your Password</td>
                            </tr>
                            <tr>
                                <td align="left">
                                    <asp:Label ID="CurrentPasswordLabel" runat="server" 
                                        AssociatedControlID="CurrentPassword">Password</asp:Label>
                                </td>
                                <td style="width: 166px">
                                    <asp:TextBox ID="CurrentPassword" runat="server" TextMode="Password"></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="CurrentPasswordRequired" runat="server" 
                                        ControlToValidate="CurrentPassword" ErrorMessage="Password is required." 
                                        ToolTip="Password is required." ValidationGroup="ChangePassword1">*</asp:RequiredFieldValidator>
                                </td>
                            </tr>
                            <tr>
                                <td align="left">
                                    <asp:Label ID="NewPasswordLabel" runat="server" 
                                        AssociatedControlID="NewPassword">New Password</asp:Label>
                                </td>
                                <td style="width: 166px">
                                    <asp:TextBox ID="NewPassword" runat="server" TextMode="Password"></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="NewPasswordRequired" runat="server" 
                                        ControlToValidate="NewPassword" ErrorMessage="New Password is required." 
                                        ToolTip="New Password is required." ValidationGroup="ChangePassword1">*</asp:RequiredFieldValidator>
                                </td>
                            </tr>
                            <tr>
                                <td align="left">

                            </tr>
                            <tr>

                                </td>
                            </tr>
                            <tr>
                                <td align="center" colspan="2" style="color:Red;">

                                </td>
                            </tr>
                            <tr>

                                    <asp:Button ID="ChangePasswordPushButton" runat="server" 
                                        CommandName="ChangePassword" Text="Change Password" 
                                        ValidationGroup="ChangePassword1" />
                                </td>
                                <td style="width: 166px">

                                </td>
                            </tr>
                        </table>
                    </td>
                </tr>
            </table>
        </ChangePasswordTemplate>
    </asp:ChangePassword>

最终，它只是一个包含必要文本框的表。我忘记了在哪里找到了这段代码，但它可能是另一篇StackOverflow帖子。

此外，请阅读http://msdn.microsoft.com/en-us/library/ms178339.aspx。它有更多关于这些模板标签如何工作的信息。
