Overrides the OnPreRender method for the associated control.
Assembly: System.Web (in System.Web.dll)
Override the method to perform target-specific processing in the PreRender stage of the control lifecycle. Typically, these are functions that immediately precede rendering of the control output.Notes to Inheritors
When you inherit from the ControlAdapter class and the adapter overrides the method, the adapter must call the corresponding base class method, which in turn calls the Control.OnPreRender method. If the Control.OnPreRender method is not called, the Control.PreRender event will not be raised.
