Datagrid reload every 'x' seconds: How to remove the visual impact

[getk]

hi guys,
First of all, thanks a lot for making easyUI. Very powerful and simpler than datatables.
I've got data which changes regulary with user interaction requirement. This needs to be displayed as a grid/table. therefore I've implemented easyUI CRUD datagrid (NOT inline editing, but the simple datagrid). Hence the datagrid needs to refresh (say every 15secs) and reload.

I'm doing like below

Code:

$(function() {
  function grid_refresh() {
	$('#dg').datagrid('reload'); // reload grid

	setTimeout(grid_refresh, 15000); // schedule next refresh after 15sec
  }

  grid_refresh();
});

My query is
1. Is there a method/option , so that easyUI can detect , if the data has changed, ONLY then reload?
2. Every 15 secs, a loading icon comes + greys out datagrid, which seems like flashing screen. Is there a way to avoid the visual flashing during reload ? i.e. can it load quietly without any visual effect on the UI

Thanks in advance.

Set 'loadMsg' property to empty string to hide the loading window.

Code:

$('#dg').datagrid({loadMsg:''});
