Syntax
'Declaration
Protected Overrides Sub AddAttributesToRender ( _
writer As HtmlTextWriter _
)
'Usage
Dim writer As HtmlTextWriter
Me.AddAttributesToRender(writer)
protected override void AddAttributesToRender (
HtmlTextWriter writer
)
protected:
virtual void AddAttributesToRender (
HtmlTextWriter^ writer
) override
protected void AddAttributesToRender (
HtmlTextWriter writer
)
protected override function AddAttributesToRender (
writer : HtmlTextWriter

Der Ausgabestream, der HTML-Inhalt für den Client rendert.
Hinweise
Diese Methode wird vorwiegend von Steuerelemententwicklern verwendet, um die entsprechenden Attribute und Formatvorlage in den HtmlTextWriter-Ausgabestream für ein Table-Steuerelement einzufügen. Diese Methode überschreibt WebControl.AddAttributesToRender.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, wie die AddAttributesToRender-Methode in einem benutzerdefinierten Serversteuerelement überschrieben wird, um der Table ein Attribut hinzuzufügen.
