How to get parent resource id

Hi,

I'm using daypilot scheduier. Dynamically i'm creating the resource tree .

My code is like below

Resource res = new Resource(StoreName, StoreID);
DayPilotScheduler1.Resources.Add(res);
res.ChildrenLoaded = true;

child = new Resource(Productname, ProductID.ToString(), true);
res.Children.Add(child);
res.ChildrenLoaded = true;
res.Expanded = true;

Loading the Stores, then loads the product for that store.

Now i'm creating the event for the product. I'm using javascript to create event TimeRangeSelectedJavaScript="createEvent(start, end, column)", this opens the popup. here i can get the product id from the column. How can i get the product id also from the parent. I'm new to daypilot scheduler.

Kindly help me on this.

Thanks
