WebControlAdapter.RenderContents Method

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

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

protected virtual void RenderContents(
	HtmlTextWriter writer
)

Parameters

writer
Type: System.Web.UI.HtmlTextWriter

The HtmlTextWriter containing methods to render the target-specific output.

The RenderContents method generates the inner markup, between the beginning and ending tags for the control. Typically, markup is generated by Render, which calls methods in the following order:

  1. RenderBeginTag.

  2. RenderContents.

  3. RenderEndTag.

Override RenderContents to generate target-specific inner markup to send to the client browser.

The RenderContents base method calls WebControl.RenderContents. The WebControl.RenderContents base method calls Control.Render, which in turn calls Control.RenderChildren. Thus, overrides of RenderContents should call the RenderContents base method only if its processing is in addition to, rather than instead of, Control.Render.

Notes to Inheritors:

For a composite control, you must ensure that the child controls are rendered. If you override the RenderContents method and do not call its base method, you can cause the child controls to be rendered by calling RenderChildren which, if not overridden, calls Control.RenderChildren from the RenderContents override.
