ControlAdapter.Render Method (HtmlTextWriter)
Generates the target-specific markup for the control to which the control adapter is attached.
Assembly: System.Web (in System.Web.dll)
Notes to Inheritors:
When you inherit from the ControlAdapter class, the base method calls the Control.Render method. Thus, overrides of the method should call the base method only if its processing is in addition to, rather than instead of, the Control.Render method.
For a composite control, the adapter developer must ensure that the child controls are rendered. If the Control.Render method causes the child controls to be rendered but does not generate markup, it might be appropriate for the method to call its base method. If target-specific rendering of the child controls is necessary, the adapter should implement the RenderChildren method and call the RenderChildren method from the method.
