First level rows expanded when i go to a page Posts

Participant

Hi
I need to have all the first level rows expanded when i go to a page.
I used this code on the ready and on the pageChanged, but it does not get all the rows.

Can you help?
Thanks

var rows = $(“#treeGrid”).jqxTreeGrid(‘getRows’);
for(var i = 0; i < rows.length; i++){
$(“#treeGrid”).jqxTreeGrid(‘expandRow’, rows[i].EmployeeKey);
}

Hi pt-jcoelho,

Are you sure that you should use “EmployeeKey”? As far as I know, the row’s key is retrieved by the “getKey” method.

Example:
