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();
