Zoomlevel Data Binding Doesn't Work

[paul]

The zoomlevel binding doesn't seem to work,
it seems to me that when i change the zoom level i the view model, the UI is not notified, the get method of the MapZoomLevel property was called only once when the map loads up. 
here is my code:

xaml:

<telerik:RadMap x:Name="RadMap" ZoomLevel="{Binding MapZoomLevel, Mode=TwoWay}" Margin="4" Provider="{Binding MapProvider}">        

<telerik:InformationLayer ItemsSource="{Binding TheSource}"/>

</telerik:RadMap>  

c#:

i use MVVM model in the project, 

my viewmodel inherits: INotifyPropertyChanged

        private int _zoomLevel;

        public int MapZoomLevel

        {

            get { return (_zoomLevel); }

            set {
 _zoomLevel = value;
RaisePropertyChanged("MapZoomLevel")
 }

        }

the same databinding works with map center and map provider.

Is this a bug in the component?

Hi Paul,

Thank you for the feedback.
We will fix this problem in some of our  future releases of RadMapl. We've created a PITS issue and you can check when the fix will be available using the following link.

The map control has the built-in zoom control that uses binding to the RadMap.ZoomLevel property.
Currently, if you want to use binding, then you should disable this zoom control. The RadMap has the ZoomBarVisibility property. To hide the zoom control you should set it to "Collapsed".
If the zoom control is displayed, then you cannot use the binding to the ZoomLevel property.

All the best,
