Add child records via Checklistbox

Pretty new with Radzen.

I am wanting a user to create a new record and select multible values from a checkboxlist and added this to a child recordset.
Parent Parent: Modules
Child Records ModuleReferences

When the user creates a Module, they have a list of references which they can add via checkboxlist and the ModuleReference is updated with the ids from ModuleReferences.

Any help would be great.
