Answer 1

Perhaps you can try to add more than 1 StoreSortInfo in your Grid List Store, ie:

listStore.addSortInfo(new StoreSortInfo<YourModelDataClass>(propertiesModel.firstSortCriteria(), SortDir.ASC));
listStore.addSortInfo(new StoreSortInfo<YourModelDataClass>(propertiesModel.secondSortCriteria(), SortDir.DESC));
listStore.addSortInfo(new StoreSortInfo<YourModelDataClass>(propertiesModel.thirdSortCriteria(), SortDir.ASC));

For the best way to present your sort criteria to user, you can use toolbar, and add some checkbox as much as your criteria, each time user check / uncheck it, just arrange your list store sort.
