findcontrol method

Hi friends, this is really simple, I basically have the same problem as this guy( see

Am gona use his soln to try and solve mine.

My question is-- why is the "dgDetails" referred to as cell(9) i can figure it out???.  thanks

Private Sub dgMaster_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgMaster.ItemDataBound
Dim drv As DataRowView = e.Item.DataItem
Dim dgChild As DataGrid = e.Item.Cells(9).FindControl("dgDetails")
dgChild.DataSource = drv.CreateChildView("ID")
End Sub
i have counted these controls from zero on wards, cant figure out why its cell(9)

The datagrid has 8 BoundColumns, followed by one TemplateColumn #9, because the index starts at zero.

The template column has two options the ItemTemplate, and the EditItemTemplate, these are both referred to as cell (9) because they are mutually exclusive, either one of the other will be rendered, but not both at the same time.
