To set a directory style as default, do one of the following
•Specify the default directory name in the ShellResultView DirectoryStyleName property in the appropriate <l:NavigatorTabItem or <l:ShellTabItem in the <TabItemList> section of the *_TABITEMS.XML file
•Specify the default directory name in the BaseQuery DefaultDirectoryStyleName property.
•Since the version 1.6, you can specify the default directory name in the searchObjectUI, e.g. <searchObjectUI name="Images" defaultDirectoryStyleName="Thumbs">
Notes
The ShellResultView DirectoryStyleName property will be used in precedence to the BaseQuery DefaultDirectoryStyleName property, unless you are using the version 1.6 or newer and the DefaultDirectoryStyleName property is set for the searchObjectUI.
