public enum SelectionRules

Member nameDescription
NoneIndicates no special selection attributes.
MoveableIndicates the component supports a location property that allows it to be moved on the screen.
VisibleIndicates the component has some form of visible user interface and the selection service is drawing a selection border around this user interface. If a selected component has this rule set, you can assume that the component implements IComponent and that it is associated with a corresponding designer instance.
LockedIndicates the component is locked to its container. Overrides the Moveable, AllSizeable, BottomSizeable, LeftSizeable, RightSizeable, and TopSizeable bit flags of this enumeration.
TopSizeableIndicates the component supports resize from the top.
BottomSizeableIndicates the component supports resize from the bottom.
LeftSizeableIndicates the component supports resize from the left.
RightSizeableIndicates the component supports resize from the right.
AllSizeableIndicates the component supports sizing in all directions.

These identifiers indicate whether a component has some form of visible user interface and whether the user can take actions to move or alter the size of the component.
