How to set grid id in javascript

[Peter]

Hi. There.
I have set up several nested grid in my application with the hierarchy grid example.
Grid
   Nest Grid 1
      Nest Grid 2
         Nest Grid 3

Both my Nest Grid 2 and Nest Grid 3 are dynamic bind in the detailInit events of grid options.
So is there a way to set Nest Grid 2 and Nest Grid 3's Id in javascript so that I can use that Id as my selector later on?
Thx in advance.

Set a grid ID that will be unique based on a unique identifier of the row it corresponds to. For example, http://dojo.telerik.com/evImu

Here I set the grid id to nested-grid-ID where ID is the employee ID of the row it corresponds to.
