Setting this property to true will prevent the control to be filled on startup of the application. This can be useful if you e.g. want to adjust property values at runtime and don't want to waste time with the initial fill of the control. The default value is false.  

When setting this property, use the FormCreate event for configuration. If the the ShellTree is part of a TFrame, due to different construction details, there is usually no need to set this property.
