Remarks
The concept of selection is different for different types of designers. When a user selects objects in a designer, there are some standard behaviors the designer should exhibit. For example, the user should be able to select an object, select multiple objects, deselect objects, and select all objects. You can use extensibility to control how the user selects objects in the designer.
Note
Other types of selection that are not covered here include text selection, where a range of text on an object is selected, and point selection, where one or more points on a curve are selected. Complex selection patterns, such as dragging a rectangle to select several objects, are handled by the TaskProvider providers of those objects.
When multiple objects are selected in a designer, one object is the primary selection object. The primary selection object is often used as a key for other behaviors. For example, to align all selected objects to the left, the primary selection object determines where to align the objects.
