I've made and example here http://jsfiddle.net/gmocnik/tXEwV/2/. The problem is the clientside sorting does not work for characthers like (č, ž, š). The second thing is, that in documentation is written "Refresh method redraws the grid using the current data of the DataSource.", but if you turn autoBind parameter to false and call grid.refresh(), nothing happens, is that OK?
Thank you in advance for help.
