System.Web 1.0.5000.0 2.0.0.0 Gtk# is thread aware, but not thread safe; See the <link location="node:gtk-sharp/programming/threads">Gtk# Thread Programming</link> for details. System.Web.UI.BasePartialCachingControl Page and control developers cannot use the class directly. ASP.NET creates an instance of the class to wrap a user control (.ascx file) when a dynamically loaded user control enables output caching. You can enable output caching for a user control using either the @ OutputCache page directive or the attribute. You add a user control to a page programmatically by calling the method. Created when a user control (.ascx file) is specified for output caching, using either the @ OutputCache page directive or the attribute, and the user control is inserted into a page's control hierarchy by dynamically loading the user control with the method. Property System.Web.UI.Control To be added: an object of type 'Control' This property returns the user control only when its output is not cached. If the user control output exists in the output cache, this property returns null, because an instance of the control is never created. Gets a reference to the user control that is cached. 1.0.5000.0 2.0.0.0
