[VB.NET][Silverlight]combo et binding dans une grid
Bonjour,
J'ai défini deux combo box, les deux étant bindé de la même manière(binder à une collection coté behind) cependant le combobox(typeclient) dans la datagrid, ne fonctionne pas, (il est vrai que le bind du datagrid se fait via code et donc apres le bind du combox hors datatgrid(combox1)).
Je me demande donc si en fait c'est possible?
Code:

molist2 = New System.Collections.ObjectModel.ObservableCollection(Of TypeClient2)
molist2.Add(New TypeClient2("grp", "groupement"))
molist2.Add(New TypeClient2("dep", "departement"))
molist2.Add(New TypeClient2("reg", "region"))
molist2.Add(New TypeClient2("com", "commune"))

Public Property MyListeTypeClient As System.Collections.ObjectModel.ObservableCollection(Of TypeClient2)
Get
Return molist2
End Get
Set(ByVal value As System.Collections.ObjectModel.ObservableCollection(Of TypeClient2))
End Set
End Property |
La combo de nom combobox1 contient bien les 4 éléments, mais pas la combo typeclient dans la grid. Quel peut en être la raison
Merci
