- HtmlTextWriter
An HtmlTextWriter that contains the HTML output to be rendered.
Remarks
The AddAttributesToRender method takes the style characteristics (if any) that are defined in the ErrorStyle object for the WebZone zone that contains an ErrorWebPart control. The styles are applied to the ErrorWebPart control prior to rendering.
Notes to Inheritors
This method can be overridden in a derived ErrorWebPart class, if developers want to customize the style characteristics that are applied to an ErrorWebPart control.
To require the WebPartManager control to use a custom ErrorWebPart control, you must also inherit from the WebPartManager class and override its CreateErrorWebPart(String, String, String, String, String) method. In that method, you should assign the value of the method's errorMessage parameter to the ErrorMessage property of your custom ErrorWebPart control, because the WebPartManager control calls this method from several other places, and usually passes in a specific error message.
