有没有办法自定义 ASP 更改密码控件中的文本框？

<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，控件内部有一个标签，可让您自定义字段。

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>

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

最终，它只是一个包含必要文本框的表格。我忘记了我在哪里找到这段代码，但它可能是另一个 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。

<div align="center">


<asp:ChangePassword ID="ChangePassword1" runat="server" BackColor="#F7F7DE" 
                BorderColor="#CCCC99" BorderStyle="Solid" BorderWidth="1px"

        </div>

.cs 文件代码

public partial class admin_Changepwd : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnectionstring"].ConnectionString);
    SqlCommand cmd;
    SqlDataReader dr;

protected void Page_Load(object sender, EventArgs e)
{

}

protected void ChangePassword1_ChangedPassword(object sender, EventArgs e)
{
    cmd = new SqlCommand("update  Admin set Password ='" + ChangePassword1.ConfirmNewPassword + "' where userid = '" + Session["userid"] + "' and Password ='" + ChangePassword1.CurrentPassword + "'", con);
    cmd.Connection.Open();
    cmd.ExecuteNonQuery();
    con.Close();

}
