InformationLayer data binding requires InvalidateArrange() on collection change

[Damian Slee]

I have tried data binding an observable collection to an InformationLayer.   But it seems it does not catch the ICollectionChange event.  informationLayer.InvalidateArrange() needs to be called manually after the collection is altered.

 

 

 

        ObservableCollection<Pushpin> _pins = new ObservableCollection<Pushpin>();

        private void radMap_InitializeCompleted(object sender, EventArgs e)
        {
            if (!this.isInitialized)
            {
                isInitialized = true;

                // initializing draagable object
                Pushpin pushpin = new Pushpin();
                ToolTip tooltip = new ToolTip();
                tooltip.Content = "3 house st";
                ToolTipService.SetToolTip(pushpin, tooltip);
                this.MakeFrameworkElementDraggable(pushpin);
                MapLayer.SetLocation(pushpin, new Location(37.747440943384, -95.2481111547551));
                _pins.Add(pushpin);

                pushpin = new Pushpin();
                this.MakeFrameworkElementDraggable(pushpin);
                MapLayer.SetLocation(pushpin, new Location(37.247440943384, -95.8481111547551));
                _pins.Add(pushpin);

                informationLayer.ItemsSource = _pins;
            }
        }



        private void Button_Click(object sender, RoutedEventArgs e)
        {
            Pushpin pushpin = new Pushpin();
            ToolTip tooltip = new ToolTip();
            tooltip.Content = "new pushpin";
            ToolTipService.SetToolTip(pushpin, tooltip);


            this.MakeFrameworkElementDraggable(pushpin);

            MapLayer.SetLocation(pushpin, new Location(36.747440943384, -94.2481111547551));

            _pins.Add(pushpin);
            informationLayer.InvalidateArrange();
        }

I have the same problem. Tried to use last build, but it does not help.

How i can call informationLayer.InvalidateArrange() from ViewModel? =)

Hello Anton,

Previous issue has been addressed to observable collection of FrameworkElements.
We have checked the latest build. It works properly.
Could you, please, create sample solution which demonstrates the problem?

Kind regards,
