InformationLayer.GetBestView() give wrong result with data binded MapPinPoint

[Gauthier]

Hi,



I tried to use the InformationLayer.GetBestView(items), but it requires to be called several times to have correct result.

(If it is called with MapPinPoint)



Here is the template of the MapPinPoint :

<DataTemplate x:Key="ObstructionPointItemTemplate"><br>
            <telerik:MapPinPoint <br>
                BorderBrush="{StaticResource ObstructionPointColor}"<br>
                Template="{StaticResource PointControlTemplate}" <br>
                telerik:MapLayer.Location="{Binding }"><br>
                <telerik:MapLayer.HotSpot><br>
                    <telerik:HotSpot X="0.5" Y="0.5" /><br>
                </telerik:MapLayer.HotSpot><br>
            </telerik:MapPinPoint><br>
</DataTemplate>

In order to eliminate any side effects with the databinding or the map provider latency, the call to 'GetBestView' is made by an event handler attached to a user interaction (MouseRightButtonDown).



I have a lightweight VS2012 solution were I reproduced the issue, if needed





Can you please help me ?





Thanks in advance

Hi Gauthier,

In the Q2 2013 release we've introduced new visualization engine in RadMap. It has been designed from scratch to have better performance. The new engine is based on the VisualizationLayer class. This is why I would recommend giving it a try. You can find more information and examples of the new layer here:

• http://www.telerik.com/help/silverlight/radmap-visualization-layer-introduction.html

• http://demos.telerik.com/silverlight/#Map/DataBinding

• http://demos.telerik.com/silverlight/#Map/ClusterVirtualization

The VisualizationLayer also contains the GetBestView() method and it should work correctly in your case. Please try it our and let us know if it helps.
