Sometimes it is necessary to locate a control contained inside a time cell. If a control is given an ID in a template, that control can be retrieved from its container (the first control in the parent hierarchy that supports INamingContainer). In this case, the container is the DataListItem control. Note that even though there are several controls with the same ID, each is contained logically in the namespace of the DataListItem container control.
You can go through the TimeView.DataList's Items collection to retrieve the DataListItem for a given index, and then call the DataListItem's FindControl method (inherited from the base Control class) to retrieve a control with a particular ID.
