Property Value

true if field values are HTML-encoded before they are displayed in a BoundField object; otherwise, false. The default is true.

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.

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