Remarks

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.

Members

Member name Description Value
Click 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 deselected. 16
MouseDown A selection that occurs when the user presses on the mouse button when 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 deselected. 4
MouseUp 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 deselected. 8
Normal A regular selection. The selection service responds to the control and shift keys to support adding or removing components to or from the selection. 1
Replace A selection that occurs when the content of a selection is replaced. The selection service replaces the current selection with the replacement. 2
Valid Identifies the valid selection types as Normal, Replace, MouseDown, MouseUp, or Click. 31
