阻止浏览器（Chrome）自动填充用户名登录文本框

Question

我想防止chrome浏览器在我创建的帐户login.aspx页面中自动填充用户名Textbox。

我尝试将Textbox的AutoCompleteMode属性设置为“无”或“禁用”，但仍然没有设置。

我用于登录的前端代码：

scope

和后端：

<asp:Login ID="LoginUser" runat="server" EnableViewState="false" RenderOuterTable="false" onloggedin="LoginUser_LoggedIn">
    <LayoutTemplate>
        <span class="failureNotification">
            <asp:Literal ID="FailureText" runat="server"></asp:Literal>
        </span>
        <asp:ValidationSummary ID="LoginUserValidationSummary" runat="server" CssClass="failureNotification" 
             ValidationGroup="LoginUserValidationGroup"/>
        <div class="accountInfo">
            <fieldset class="login">
                <legend><asp:Literal ID="Literal3" runat="server" Text="<%$ Resources:chienvh.language, AccountInformation%>" /></legend>
                <p>
                    <%--<asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">Username:</asp:Label>--%>
                    <asp:TextBox ID="UserName" runat="server" CssClass="textEntry" AutoPostBack="true" Placeholder="<%$ Resources:chienvh.language, Username%>" OnTextChanged="UserName_TextChanged"></asp:TextBox>
                    <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName" CssClass="failureNotification"
                                                ErrorMessage="User Name is required." ToolTip="User Name is required." 
                                                ValidationGroup="LoginUserValidationGroup">*</asp:RequiredFieldValidator>
                </p>
                <p>
                    <%--<asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>--%>
                    <asp:TextBox ID="Password" runat="server" CssClass="passwordEntry" TextMode="Password" Placeholder="<%$ Resources:chienvh.language, Password%>"></asp:TextBox>

                         CssClass="failureNotification" ErrorMessage="Password is required." ToolTip="Password is required." 
                         ValidationGroup="LoginUserValidationGroup">*</asp:RequiredFieldValidator>
                </p>
                <p>

                                                      from Site
                                                      order by [Site]"></asp:SqlDataSource>
                </p>
                <p>
                    <asp:CheckBox ID="RememberMe" runat="server"/>
                    <asp:Label ID="RememberMeLabel" runat="server" AssociatedControlID="RememberMe" CssClass="inline">Keep me logged in</asp:Label>
