Is there any way to make group view not expanded as default?

[aswzen]

Yes, is there any way or option that i should set to make group view not expanded as default?

i don't want to use this code below because it will consume so much render time..

Code:

$('#dg').datagrid({
	onLoadSuccess:function(){
		var gcount = $(this).datagrid('options').view.groups.length;
		for(var i=0; i<gcount; i++){
			$(this).datagrid('collapseGroup', i);
		}
	}
})

here the fiddle

thanks in advance
