Forms within the DocumentManager can be presented in either the NativeMdiView or the TabbedView. For both these options, the Document Selector can be used. Invoked via the CTRL+TAB or CTRL+SHIFT+TAB shortcut, it allows you to switch to a specific document or dock panel (much like Microsoft Visual Studio). The following figure illustrates what the Document Selector looks like:
Users can press the TAB and Arrow keys to navigate within the Document Selector. A small preview of the currently focused item is displayed for ease of navigation. When an end-user displays/hides a document selector, the DocumentSelectorShown and DocumentSelectorHidden events are fired. You can also check if a document selector is currently displayed via the IsDocumentSelectorVisible property.
The default UseDocumentSelector value works the same as true, enabling the Document Selector.
