Parameters
| Parameters | Description |
| Parent: IJvDataItem | Either a reference to the parent item or a 0-based index in the view list of the parent item. Allowed values for the index version ranges from 0 to Count-1. |
| Index: Integer | 0-based index of the child item to retrieve. |
Description
SubItem retrieves a reference to the specified child item of the specified parent item. The two versions of this method allow to specify the parent either as a data item or as a 0-based index in the view list. If the parent item could not be found either an exception is raised or a nil pointer is returned (depends on the implementer). If the item has no children or the index is out of range either an exception is raised or a nil pointer is returned (depends on the implementer). Most implementers will choose to return a nil pointer in this case, as there's no real way to tell the number of child items an item has.
