Maintaining sort after grid refresh.

I am using v2b3.

I am developing an app that updates the grid data in the background asynchronously. I would like to keep the grid sorting across a call to Grid.refresh(). I've tried using set/getSortModel(), but the model doesn't seem to updated when the user clicks on the grid header to sort. Most likely I am doing something wrong.

Found my own answer: perhaps someone else can benefit:

// get sort properties
var sortColumn = grid.getSortColumn();
var sortDirection = grid.getSortDirection(sortColumn);

// refresh grid
grid.clearRowModel();
grid.setRowCount(model.getCount());
grid.refresh();

// reinstate sorting
if (sortColumn != -1) {
grid.sort(sortColumn, sortDirection);
}

LostInSpace, I was having the same problem, and your solution worked. Thank you!

Hmm, I'm really having problems getting this working and was wondering if anyone had any ideas...

function getData(url) {
    data.setURL(url);
    data.request();
  }

  function resortData() {
    // get sort properties
    var sortColumn = table.getSortColumn();
    var sortDirection = table.getSortDirection(sortColumn);
 
    // refresh grid 
    table.clearRowModel();
    table.setRowCount(data.getCount());
    table.refresh();

    // reinstate sorting
    if (sortColumn != -1) {
      table.sort(sortColumn, sortDirection);
    }
  }

  function reloadData() {
    var url;                                                                             
    var d = new Date();                                                                  
    var tab = tabs.getSelectedItems();                                                   
    var type = 'all';                                                                    
      if (tab == 1)                                                                        
        type = 'my';                                                                       
      else if (tab == 2)                                                                   
        type = 'chronic';                                                                  
                                                                                             
    url = data_url + type +"&" + d.getTime();                                            
                    
    getData(url);
    resortData();
    self.setTimeout(reloadData, $reload_time * 1000);                                        
  }
