In wcmqs I've created a form for entering booking requests (b:BookingRequest) and a custom data list (bdl:BookingRequestDataList). How can I show my BookingRequests in my datalist?
I'm afraid I don't fully understand the question. If you have created a data list and you are placing your booking requests into it then they should appear in the "Data Lists" area of Share. The visitor feedback feature of WQS uses data lists and data list items so you may find clues there for how to make it work. Note that nodes that appear in data lists must be derived from the dl:dataListItem type. Does your b:BookingRequest type?
