c# - nested property listbox -

i use ef , set datasource of bindingsource user.

now in listbox set valuemember asuserid , displaymember product.productname (nested property)

schemat is:

 user _________ userid username productid   product _________ productid productname

i bind lot of users control , display productnames there visible 1 productname though there example 4 users.

the classes generated ef partial, can create source file , add property user class, that:

public partial class user {     public string productname { { return this.product.productname; } } }

this way not need access nested properties displaymember.
