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);
}
