ControlAdapter.BeginRender Method

Called prior to the rendering of a control. In a derived adapter class, generates opening tags that are required by a specific target but not needed by HTML browsers.

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

protected internal virtual void BeginRender(
	HtmlTextWriter writer
)

Parameters

writer
Type: System.Web.UI.HtmlTextWriter
The HtmlTextWriter containing methods to render the target-specific output.

The BeginRender method is called just before the Render method, and is used to perform target-specific preprocessing before the rendering of the control.

Use the BeginRender method in combination with the EndRender method to ensure opening and closing tag consistency.

Notes to Inheritors

When you inherit from the ControlAdapter class, the BeginRender base method calls the BeginRender method. Thus, overrides of the BeginRender method should call the BeginRender base method only if its processing is in addition to, rather than instead of, the HtmlTextWriter.BeginRender method.
