About ListField in Blackberry

Plz give the code or function how to clear the ListField and update the ListField . Suppose i want to display some multiple text( Project Name, Project Manager )extracted from JSON object , in a ListField. I am able to display this strings in the ListField but one more feature i need to add ie.. above the ListField there should be a ButtonField and when the user clicks on the ButtonField the ListField should display the string in sorted manner base on Project Name. So i need to clear the ListField.

Implement ListFieldCallback in your screen, you can then handle the drawing of your rows however you want in drawListRow.

In this sort of circumstance, I would recommend that you sort the data you are using in the ListField, cfeate a new ListField based on the sorted data, and then delete the old ListField and add your new one.
