I think you need to write:
cmb_rues.DataSource = Rues; cmb_rues.DisplayMember = "Nom"; cmb_rues.ValueMember = "Id"; -
Hello I've try it too !! Same result BUT If I declare the ValueMember I got a message cannot bind to the new displaymember
-
Try this:
class Rue { public int Id; public string Nom; public override string ToString() { return Nom; } }; -
Thank you It works indeed ! But I really do not understand why and how ? I'm old to C but new to csharp and oop
-
The combobox run ToString() for each item. If you have a class, that does not override the ToString() method, it returns the name of the class- type. I guess you don't need to run
cmb_rues.DisplayMember = ...?? -

Thanks for any help !Create properties for your members and let the display member be a property. It should work. Let me know if it doesn't.
