LoginName Class

Note: This class is new in the .NET Framework version 2.0.

Displays the value of the System.Web.UI.Page.User.Identity.Name property.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public class LoginName : WebControl
/** @attribute BindableAttribute(false) */ 
public class LoginName extends WebControl
public class LoginName extends WebControl

By default, the LoginName control displays the name contained in the User property of the Page class. If the System.Web.UI.Page.User.Identity.Name property is empty, the control is not rendered.

To change the text displayed by the LoginName control, set the FormatString property.


The LoginName control cannot be used outside the <form> tag on a Web page. Specifically, the LoginName cannot be used to put the user's name in the title of a page.


The markup rendered by default for this control might not conform to accessibility standards such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. For details about accessibility support for this control, see ASP.NET Controls and Accessibility.

The following code example shows how to use the LoginName class on a page. Clicking the button changes the display format.

<%@ Page Language="C#" autoeventwireup="False" %>
<script runat="server">

    void Button1_Click(Object sender, EventArgs e) {
        LoginName1.FormatString = "Welcome to our Web site, {0}";
         Button1.Visible = false;

    <form runat="server">
            <asp:LoginName id="LoginName1" runat="server" 
               FormatString ="Welcome, {0}" />
            <asp:Button id="Button1" onclick="Button1_Click" runat="server" 
               Text="Change Format" />
