LoginName Class

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)

[BindableAttribute(false)] 
public class LoginName : WebControl
/** @attribute BindableAttribute(false) */ 
public class LoginName extends WebControl
BindableAttribute(false) 
public class LoginName extends WebControl
Not applicable.

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.

NoteNote:

If you are not familiar with the set of login controls available in ASP.NET, see ASP.NET Login Controls Overview before continuing. For a list of other topics related to login controls and membership, see Managing Users By Using Membership.

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

NoteNote:

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.

Accessibility

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.
