Render Method

ControlAdapter.Render Method

Generates the target-specific markup for the control to which the control adapter is attached.

Namespace:  System.Web.UI.Adapters
Assembly:  System.Web (in System.Web.dll)

Protected Friend Overridable Sub Render ( _
	writer As HtmlTextWriter _


Type: System.Web.UI.HtmlTextWriter

The HtmlTextWriter to use to render the target-specific output.

Override the Render method to generate target-specific markup to send to the client browser. The Render method is called in place of the Control.Render method if a ControlAdapter object is attached to a Control object.

Notes to Inheritors

When you inherit from the ControlAdapter class, the Render base method calls the Control.Render method. Thus, overrides of the Render method should call the Render 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 Render 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 Render method.
