You use the RegisterExpandoAttribute method to register a custom (expando) property for a control that is compatible with partial-page rendering and that has no Microsoft AJAX Library dependencies. 

The RegisterExpandoAttribute method registers a name/value pair as a custom attribute for the specified control. The property is set dynamically from ECMAScript (JavaScript) to preserve XHTML compatibility for the rendered control's markup. Set encode to true if you have to escape any characters in the dynamic property's value.

If the control to which the dynamic property will be added is not found, a script error occurs.
