StyleSheet Class

Organizes styles that will be applied to other controls.

Namespace:  System.Web.UI.MobileControls
Assembly:  System.Web.Mobile (in System.Web.Mobile.dll)

public class StyleSheet : MobileControl
<mobile:StyleSheet />

A StyleSheet control can contain any number of style objects, or more specialized style objects that inherit from the Style class. These should have unique name properties. You can then refer to other controls on the same page by their Name property. This class has no visual representation.

A page can also use an external style sheet, and several pages can share the same external style sheet. For more information about styles, refer to the <Style> Element element and the Styles topic.

NoteNote:

The StyleSheet control ignores its own style attributes; setting a style attribute on the StyleSheet itself has no effect on the styles contained as children within the StyleSheet control.

The following example shows how you can add Style properties to a StyleSheet control during the Page_Load event.

<%@ Page Language="C#" 
    Inherits="System.Web.UI.MobileControls.MobilePage" %>
<%@ Register TagPrefix="mobile" 
    Namespace="System.Web.UI.MobileControls" 
    Assembly="System.Web.Mobile" %>
<%@ Import Namespace="System.Web.UI.MobileControls" %>
<%@ Import Namespace="System.Drawing" %>

<script runat="server">
    protected void Page_Load(Object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            StyleSheet1["Style1"].ForeColor = Color.Red;
            StyleSheet1["Style1"].Font.Size = 
                System.Web.UI.MobileControls.FontSize.Large;
            StyleSheet1["Style1"].Font.Bold = BooleanOption.True;
            StyleSheet1["Style1"].Font.Italic = BooleanOption.True;
            StyleSheet1["Style2"].ForeColor = Color.Blue;
            StyleSheet1["Style2"].Font.Size = 
                System.Web.UI.MobileControls.FontSize.Normal;
            StyleSheet1["Style2"].Font.Bold = BooleanOption.False;
            StyleSheet1["Style2"].Font.Italic = BooleanOption.True;
            StyleSheet1["Style3"].ForeColor = Color.Green;
            StyleSheet1["Style3"].Font.Size = 
                System.Web.UI.MobileControls.FontSize.Small;
            StyleSheet1["Style3"].Font.Bold = BooleanOption.False;
            StyleSheet1["Style3"].Font.Italic = BooleanOption.False;
        }
    }

    void SelectStyle(object sender, EventArgs e)
    {
        // Retrieve the style name as a string.
        String myStyle = SelectionList1.Selection.ToString();

        // Match the style name and apply the style to TextView1. 
        switch (myStyle)
        {
            case "hot":
                TextView1.StyleReference = "Style1";
