Telerik mvc3 treeview get node level client-side

Question

I have a treeview with check box. When a check box is clicked, I need, client-side, to know the node level of the node just selected. exemple:

[ ] Node (level 1)
  [x] Node (level 2)
  [ ] Node (level 2)
  [ ] Node (level 2)
  [ ] Node (level 2)
[ ] Node (level 1)
  [ ] Node (level 2)
  [ ] Node (level 2)
  [ ] Node (level 2)

I dont see any property in the event parameter that could tell the level of the node. A viable workaround would be to add, server side, an attribute to the node to indicate the level (for exemple data-level="1").

The following code should return the level of a node:

var level = $(e.item).parents(".t-item").length;

What it does is to find all parent elements that have the "t-item" CSS class which happen to be the parent nodes.

Well that seems like it would works. I would have prefered to add a tag to the item for the level. My colleague is sick today so I will not try it until tomorrow.
