You can use the ItemContainerGenerator to retrieve items based on their index or containers by specifying the data item. For example, if you have a data-bound ItemsControl, and you want to obtain an item based on its index, you can use the ItemContainerGenerator.ContainerFromIndex method. If you want to retrieve the data item, use ItemContainerGenerator.ItemFromContainer method.
