I'm using a QueryFilter.Search to populate a ListBox with the name of all the records. Once all the records are shown, I want to be able to allow a user to filter them according to a string of characters. For this I'm creating a new QueryFilter in which the WhereClause is "FIELD LIKE '%" + NamePart + "%'". However I can't figure out why this new QueryFilter doesn't work even with no WhereClause. Does some one know why? Should the new search be "reset" in some way?
