c# - How to accomplish this binding -


i have following scenarion. have object, lets call x needs set datacontext of combobox.

object x consists of 3 objects.

  • propa - object => id, propb_id
  • propb - collection of objects => id, propc_id
  • propc - collection of objects => id, text

they related each other.

  • propa:propb -> n:1
  • propb:propc -> n:1

all of ids set , valid, not have references between eachother. there no integrity between them.

so need have combobox items represent collection propb, show "text" propery propc , selected item (propb) set "selectedid" in propa

i have no idea how acompluish this. if have references between eachother no problem, since not, not do.
