WebControlAdapter.RenderBeginTag Method

Creates the beginning tag for the Web control in the markup that is transmitted to the target browser.

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

protected virtual void RenderBeginTag(
	HtmlTextWriter writer
)

Parameters

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

Override the RenderBeginTag method to write additional markup tags or add attributes to the beginning tag for the WebControl object. Use RenderBeginTag in conjunction with the RenderEndTag method to assure beginning and ending tag consistency.

Notes to Inheritors

The RenderBeginTag base method calls the WebControl.RenderBeginTag method. In turn, the WebControl.RenderBeginTag base method calls the appropriate HtmlTextWriter.RenderBeginTag overload, which is determined by the type of tag with which the WebControl object was created. You can avoid overriding RenderBeginTag by deriving from the HtmlTextWriter class and overriding HtmlTextWriter.RenderBeginTag, and also possibly HtmlTextWriter.RenderEndTag.
