Hello Martin,

Thank you for reporting this behavior. As a workaround, we can create a custom class that derives from RadTreeView and override the OnNotifyPropertyChanged method. In the method we can avoid executing the default code and only raise the property changed.

class CustomRadTreeView: RadTreeView
{
protected override void OnNotifyPropertyChanged(PropertyChangedEventArgs e)
{
    //base.OnNotifyPropertyChanged(e);
    PropertyChangedEventHandler handler1 =
        (PropertyChangedEventHandler)this.Events[new object()];
    if (handler1 != null)
    {
        handler1(this, e);
    }
}

}

Regards,
