I have some data in a flex grid which is not coming from any database. The grid is filled with data as user selects few objects in the program. I want to sort this data with multiple sorts, how do i do that? I have figured out how to sort with just 1 column by using the grid1.sort = flexsortstringascending, but i dont know how can i sort using column 1 and then by column 2, etc. Any suggestion would be highly appreciated.
