Update/Insert/Delete in Hierarchy

[El]

I have an extra RadGrid as Detail Table which needs to be editable (update, insert, delete). 

I thought that DetailTable contains the needed Event Handlers for that but obviously i was wrong. 

So now, i don't know how do i do that. I am using RadGrid1_DetailTableDataBind event to bind the nested Grid to Datatable:

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

 If e.DetailTableView.Name = "Payments" Then
     Dim PurchaseID As Integer = Convert.ToInt16(dataItem.GetDataKeyValue("SaleID").ToString)
     e.DetailTableView.DataSource = PurchasesAccess.GetPayments(PurchaseID)
 End If

However i still don't know how do i call UpdateCommand, InsertCommand and DeleteCommand for the grid which is detail table. 

I am not using SqlDataSource objects and such. Rather i am using classes and stored procedures. 

Thanks

I have a 3-level grid which does insert/update/delete on all but the highest level

I believe i should check if it's radgrid or gridtableview in all RadGrid's events and response adequately. e.g. In the ItemDataBound i should also Bind the gridtableview's controls but if the typeof object is gridtableview etc. 

I am assuming which is probably not right but, the above example actually does not suit my scenario. 

Thank you so much

all you have to do is check e.Item.OwnerTableView.Name to know which level generated the event
