Return Value

A localized human-readable string value that indicates funtionality of the control, specifically its sorting mode if any.
Remarks
This implementation overloads the usual generalized meaning of the "HelpText" concept in order to report information about the current grid column sorting mode. Specifically, the implementation returns a localized human-readable resource string that indicates whether sorting is active, and whether sorted by ascending or descending value. The sorting mode is typically also indicated to users through the use of icons in the default templates. The sorting mode is also exposed as HelpText by the default peer implementation in order to address accessibility scenarios.
If the owner is not sortable, this implementation calls base.
