Specifies a response variable to receive a field name used for server-side sorting. If omitted, client-side sorting is used. The response represents the name of the field bound to the first widget in a column of the grid. It is the responsibility of the program to keep track of the sort direction, and to display an up or down arrow in the appropriate column using the "initial sort field" and "default sort order" properties.
Possible Values: Must be bound
With Profound UI versions newer than Version 6 Fix Pack 2.1, the grid supports sorting of multiple columns at once. With multiple columns chosen, the grid submits "field name sort response" as a comma-separated list of column numbers and "return sort order" as a comma-separated list of characters. The server-side program must be able to parse the comma-separated list and provide comma-separated lists to the "initial sort column" and "default sort order" properties.
