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

public virtual FontInfo Font { get; }
/** @property */
public FontInfo get_Font ()

public function get Font () : FontInfo

Property Value

A FontInfo that represents the font properties of the Web server control.

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).


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.

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


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.

<%@ Page Language="C#" AutoEventWireup="True" %>

    <script language="C#" runat="server">
        void Button1_Click(Object sender, EventArgs e) {
           Label1.Text = "The font this label uses is: " + Label1.Font.ToString();
        void Button2_Click(Object sender, EventArgs e) {
           Label1.Font.Underline = true;
    <h3>FontUnit Property of a Web Control</h3>
 <form runat="server">
    <asp:Label id="Label1" 
     Font-Name="Verdana" Font-Size="10pt"
     Text="This is a Label control."
    <asp:Button id="Button1"
     Text="Click to gather font info of the label control"
    <asp:Button id="Button2"
     Text="Click to underline the text of the label control"
