FontInfo.Underline Property

Gets or sets a value that indicates whether the font is underlined.

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

public bool Underline { get; set; }

Property Value

Type: System.Boolean
true if the font is underlined; otherwise, false. The default value is false.

Use the Underline property to specify or determine whether the font contains a line under the text.

The value of this property is stored in view state.

NoteNote

The font underline behavior for links generated by the LinkButton, HyperLink, and HtmlAnchor controls is affected by setting the Strikeout and the Overline properties of the FontInfo for the control. If the Strikeout or the Overline properties are set, regardless of their value, you must set the Underline property explicitly if you want the link to be underlined.

The following example demonstrates how to use the Underline property to programmatically specify an underlined font for a Label control.
