Components of a designer document can be selected using the SetSelectedComponents method of the ISelectionService. Some types of actions can operate on a selected component or group of selected components. The ISelectionService keeps track of the selection type of the current selection. These selection type identifiers indicate whether the selection was completed using a single click, a mouse down or mouse up selection, whether the selection should replace the previous selection, or use the default selection mode.
Use the SelectionTypes enumeration to specify the type of a selection when setting a new selection using the SetSelectedComponents method.
