ingCellStyle is declared globally, i set its property in the New() sub. then on the loadDetails i apply this style to rows that pass the conditon. I have had a similar issue before, where i was loading multiple Tabs with a GridView on each tab, evenThough i'd called the restyling on the load event, only the focused Tab seemed to display the changes. The work around was to call the Restyling method on the Tab.selectedIndex change.
