StyleSheet Class

.NET Framework 1.1

Organizes styles that will be applied to other controls.

public class System.Web.UI.MobileControls.StyleSheet : 
   System.Web.UI.MobileControls.MobileControl

Remarks

The 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 and the Styles topic.

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

Example

This example shows how you can add Style properties to a StyleSheet control during the page load event.
