Html32TextWriter.RenderBeforeTag Method ()

 

Writes any text or tab spacing that occurs before the opening tag of an HTML element to the HTML 3.2 output stream.

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

protected override string RenderBeforeTag()

Return Value

Type: System.String

The HTML font and spacing information to render before the tag; otherwise, if there is no such information to render, null.

The following code example demonstrates how to override the RenderBeforeTag method. The code checks whether an a element is being rendered. If so, the overridden RenderBeforeTag method writes the opening tag of a small element. The sample for the RenderAfterTag performs the same check for the a element, and then writes the closing tag of the small element.

This code example is part of a larger example provided for the Html32TextWriter class.

      // Override the RenderBeforeTag method to render the
      // opening tag of a <small> element to modify the text size of 
      // any <a> elements that this writer encounters.
protected override string RenderBeforeTag()
{
          // Check whether the element being rendered is an 
          // <a> element. If so, render the opening tag
          // of the <small> element; otherwise, call the base method.
	if (TagKey == HtmlTextWriterTag.A)
		return "<small>";
	return base.RenderBeforeTag();
}
