Easily utilize all of the style-sheet manager’s functionality with a simple drag-and-drop onto your page. Take advantage of the control’s SmartTag to configure the control with no need for additional code.
Caching Support
Utilize the built-in caching to further improve page performance. The caching feature enables all CSS style sheets that would come from your page to be loaded from cache.
Minimizing Page Traffic
Automatically combine all CSS style sheets associated with the Telerik ASP.NET Ajax controls into a single request by simply dropping this control onto your page. This greatly reduces page traffic on pages with multiple Telerik controls.
