Hello xpblack,
If you are using the items[] array approach for creating the tree list, you can access and edit the elements directly through the dataAdapater and update them there and then reset the source for the tree.
Alternatively you can loop through the element.subtreeElement.children
var selectedItem = ('#jqxTree').jqxTree('getItem', myItem);
if (selectedItem.subtreeElement){
for (var i = 0; i< selectedItem.subtreeElement.children.length; i++) {
var childElement = $('#jqxTree').jqxTree('getItem', selectedItem.subtreeElement.children[i]);
// do stuff to childElement
}
}
Note that this will only get the first level children. If you need it to be recursive you will need to make it recursive yourself.
Best Regards,
Vladimir
