The container control supports the following selection types:

• Single selection

  Single selection enables a user to select only one container item at a time. This is the default selection type for all views and is the only selection type supported for the Tree view.

• Extended selection

  Extended selection enables a user to select one or more container items, in any combination. The CUA-defined keyboard augmentation keys are implemented for extended selection. When used with a pointing device, these keys enable a user to select discontiguous sets of container items. Extended selection is valid for all views except the Tree view.

• Multiple selection

  Multiple selection enables a user to select none, some, or all of the container items. Multiple selection is valid for all views except the Tree view.

Only one of these selection types can be used for each container. The selection type for a container is defined when the container is created.
