❔ WPF Binding to collection in static instance not updating list

I have a collection in a static member of a class that's being changed. It should be firing

PropertyChanged

PropertyChanged

for the property shown below. But the list never updates.

dgPredefined.SetBinding(System.Windows.Controls.ItemsControl.ItemsSourceProperty, new System
    .Windows.Data.Binding("AllItemsSortedByName")
    {
        Source = Data.NetworkMgr.mgr,
        NotifyOnTargetUpdated = true,
    });

dgPredefined.SetBinding(System.Windows.Controls.ItemsControl.ItemsSourceProperty, new System
    .Windows.Data.Binding("AllItemsSortedByName")
    {
        Source = Data.NetworkMgr.mgr,
        NotifyOnTargetUpdated = true,
    });

The original plan was to declare it in the XAML, but I haven't figured out the equivalent syntax. Can someone tell me what I'm doing wrong? I tried both

NotifyOnTargetUpdated

NotifyOnTargetUpdated

as shown above and

NotifyOnSourceUpdated

NotifyOnSourceUpdated

. My orignal impression was the latter is for when the control needs to be notified the source has changed. But after reading the documentation, it looks like it's the other way around. With

Data.NetworkMgr.mgr

Data.NetworkMgr.mgr

Data

Data

is a namespace,

NetworkMgr

NetworkMgr

is a class, and

mgr

mgr

is the static instance of

Data.NetworkMgr

Data.NetworkMgr
