Assembly: System.Design (in system.design.dll)
The LoginName control renders a label that contains the name of the current user.
In a visual designer, when you switch from Source to Design view, the markup source code that describes the LoginName control is parsed and a design-time version of the control is created on the design surface. When you switch back to Source view, the design-time control is persisted to the markup source code and edited into the markup for the Web page. The LoginNameDesigner class provides design-time support for the LoginName control.
The UsePreviewControl property always returns true, indicating that the designer creates a temporary copy of the associated LoginName to generate the design-time markup. The GetErrorDesignTimeHtml method provides the markup that is used to render the associated LoginName at design time when an error has occurred.
