.NET Framework Class Library

WebControl..::.Font Property

Gets the font properties associated with the Web server control.

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

Syntax

Visual Basic (Declaration)

Public Overridable ReadOnly Property Font As FontInfo

Visual Basic (Usage)

Dim instance As WebControl
Dim value As FontInfo

value = instance.Font

public virtual FontInfo Font { get; }

Visual C++

public:
virtual property FontInfo^ Font {
    FontInfo^ get ();
}

JScript

public function get Font () : FontInfo

Property Value

Type: System.Web.UI.WebControls..::.FontInfo
A FontInfo that represents the font properties of the Web server control.

Remarks

Use the Font property to specify the font properties of the Web Server control. This property includes subproperties that can be accessed declaratively in the form of Property-Subproperty (for example Font-Bold) or programmatically in the form of Property.Subproperty (for example Font.Bold).

All but one subproperty will render in browsers prior to Microsoft Internet Explorer version 4 for all controls. They are: Bold, Italic, Name, Names, Strikeout, Underline, and Size (but only named font sizes, such as Small, Smaller, and so on, will work).

Note:
Although these subproperties render in browsers prior to Microsoft Internet Explorer version 4, the HTML that is rendered is different than later browsers. Instead of rendering as style attributes, these subproperties are rendered as HTML elements, such as <b> and <font>.

The one subproperty that will not render on earlier browsers for all controls is Overline.

Examples

The following example illustrates how to use the Font property to gather font information from a Label control.

Note:
The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model.
