Binding dont refresh, even when explicitly calling UpdateTarget

Question

My ListView does not refresh its bindings when i call OnPropertyChanged. I have tried to force it to refresh by:

NestedArguments.GetBindingExpression(ItemsControl.ItemsSourceProperty).UpdateTarget();

But still, no luck!

YES, it does get updated. I have set a breakpoint and checked.

What is going on?

Other bindings seem to work without a problem

Answer 1

You are implement http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged.aspx interface?

Answer 2

is your onpropertychanged("") spelled correctly? its silly but it happens and if you arent checking for it you may miss it...

also how are you setting it? if it is a child property of a parent property you have to put the onpropertychanged notification for the child property in the parent property...

Public Property SelectedDoctorTaxonomy() As DoctorTaxonomy
            Get
                Return _objSelectedDoctorTaxonomy
            End Get
            Set(ByVal Value As DoctorTaxonomy)
                _objSelectedDoctorTaxonomy = Value
                OnPropertyChanged("SelectedDoctorTaxonomy")
                OnPropertyChanged("DoctorID")
                OnPropertyChanged("TaxonomySpecializationID")
                OnPropertyChanged("TaxonomyTypeID")
                OnPropertyChanged("TaxonomyClassificationID")
                OnPropertyChanged("AddDate")
                OnPropertyChanged("AddUserID")
                OnPropertyChanged("ChangeDate")
                OnPropertyChanged("ChangeUserID")
            End Set
        End Property
