We are aware of this limitation and have plans to introduce an API for implementing the functionality to avoid selecting certain rows. In the meantime, we recommend that you manually deselect rows you do not want to be selected in the onSelectionChanged handler. Check the https://www.devexpress.com/Support/Center/Question/Details/T497347 ticket illustrating how to implement this.
