Member nameDescription
Add

Represents an add selection that adds the selected components to the current selection, maintaining the current set of selected components.

Auto

Represents a regular selection. The selection service responds to the CTRL and SHIFT keys to support adding or removing components to or from the selection.

Click

Obsolete.Represents a selection that occurs when a user clicks a component. If the newly selected component is already selected, it is promoted to be the primary selected component rather than being canceled.

MouseDown

Obsolete.Represents a selection that occurs when the user presses on the mouse button while the mouse pointer is over a component. If the component under the pointer is already selected, it is promoted to become the primary selected component rather than being canceled.

MouseUp

Obsolete.Represents a selection that occurs when the user releases the mouse button immediately after a component has been selected. If the newly selected component is already selected, it is promoted to be the primary selected component rather than being canceled.

Normal

Obsolete.Represents a regular selection. The selection service responds to the CTRL and SHIFT keys to support adding or removing components to or from the selection.

Primary

Represents a primary selection that occurs when a user clicks on a component. If a component in the selection list is already selected, the component is promoted to be the primary selection.

Remove

Represents a remove selection that removes the selected components from the current selection, maintaining the current set of selected components.

Replace

Represents a selection that occurs when the content of a selection is replaced. The selection service replaces the current selection with the replacement.

Toggle

Represents a toggle selection that switches between the current selection and the provided selection. If a component is already selected and is passed into SetSelectedComponents with a selection type of Toggle, the component selection will be canceled.

Valid

Obsolete.Identifies the valid selection types as Normal, Replace, MouseDown, MouseUp, or Click.

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.
