| HtmlTextWriter | marshal by reference, disposable |
| System.Web.UI (system.web.dll) | class |
The ASP.NET framework uses this class when writing the client-side
HTML for a Web Forms page. It contains a wealth of methods for
rendering the appropriate content, and derives from the more generic
System.IO.TextWriter. Typically, you will not use
this class directly in your code, unless you are a control developer.When deriving custom controls from Control or
System.Web.UI.WebControls.WebControl, you can
override the Render( ) or RenderContents(
) method and create the control's output
by using the supplied HtmlTextWriter. Commonly
used methods include Write( ), which can output
text or HTML tags, AddStyleAttribute( ), which
specifies a CSS style attribute for the next tag, and
RenderBeginTag( ) and RenderEndTag(
), which make it easy to insert open and closing HTML tags
while keeping the code readable. The
HtmlTextWriter also performs automatic indentation
of the HTML output.public class HtmlTextWriter : System.IO.TextWriter {
