Remarks

Use the HtmlEncode property to specify whether field values are HTML-encoded to their respective string representations before they are displayed in a BoundField object.

NoteNote:

HTML-encoding field values helps to prevent cross-site scripting attacks and malicious content from being displayed. This property should be enabled whenever possible.

Sample does nothing useful.
The Sample does nothing useful. Please provide a sample where you would want to use HTML encoding - and where you would want to disable it) - and why. If they both produce the same output, why would you bother to disable it and open yourself to XSS.
