Style.Font Property
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the font properties associated with the Web server control.
public:
property System::Web::UI::WebControls::FontInfo ^ Font { System::Web::UI::WebControls::FontInfo ^ get(); };public System.Web.UI.WebControls.FontInfo Font { get; }member this.Font : System.Web.UI.WebControls.FontInfoPublic ReadOnly Property Font As FontInfoProperty Value
A FontInfo that represents the font properties of the Web server control.
Examples
This example demonstrates how to use a Style object to change the style properties of multiple controls at once. Each time one of the Style property values changes, each control must call its ApplyStyle method. Note that not all the controls included support all the properties demonstrated. If a control does not support a particular property, the appearance of the control will not change when the property value is changed.
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 Forms Page Code Model.

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 in later browsers. Instead of rendering as style attributes, these subproperties are rendered as HTML elements, such as <b> and <font>.
One subproperty that will not render on some browsers is Overline.
