Grid cannot at the moment determine if all child nodes of a parent are selected because of the lazy loading, the same applies to the master checkbox. The ticket is considered to be an enhancement request. Additionally it's not necessarily the desired behaviour, e.g. file-folder structure where you want to select file nodes and the folder.
