Hi Muhammad You can use ZoneUpdater for that.
http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html So in your select you will have <select t:type='select' t:mixins='zoneupdater' t:zone='whatever_zone' t:event='updateColumn' t:context='widthIndex' t:clientEvent='onchange'/> and <select t:type='select' t:mixins='zoneupdater' t:zone='whatever_zone' t:event='updateRow' t:context='heightIndex' t:clientEvent='onchange'/> Object onColumnUpdate(int widthIndex){ ... return columnZone.getBody(); } Object onRowUpdate(int heightIndex){ return rowZone.getBody(); } On Mon, Sep 5, 2011 at 11:32 PM, Muhammad Gelbana <m.gelb...@gmail.com> wrote: > Hi All, > > I've been trying to do this for some time now but nothing worked.
