Context Menu on Polygon

[Amit]

Hi,

I ​have loaded multiple polygons from SQL on a bing map and have a context menu for the polygons on the information layer.

However, I cant find any way to bind and get the unique id of the clicked polygon.

<telerik:InformationLayer x:Name="infoLayer" >
                <telerik:InformationLayer.Reader>
                    <telerik:SqlGeospatialDataReader Source="{Binding SpatialData}" x:Name="Data"
                                                     GeospatialPropertyName="Polygon"
                                                     ToolTipTemplate="{StaticResource ToolTipDataTemplate}"
                                                     />
                </telerik:InformationLayer.Reader>
                <telerik:InformationLayer.ContextMenu>
                    <ContextMenu x:Name="PolygonMenu">
                        <MenuItem Header="Menu Item 1" Command="{Binding Path=PolygonSelectedCommand}"
                                  CommandParameter="{Binding ElementName=infoLayer,Path=????}"/>
                    </ContextMenu>
                </telerik:InformationLayer.ContextMenu>

                <telerik:InformationLayer.ShapeFill>
                    <telerik:MapShapeFill Fill="Transparent"  Stroke="Red" StrokeThickness="1" />
                </telerik:InformationLayer.ShapeFill>
                <telerik:InformationLayer.HighlightFill>
                    <telerik:MapShapeFill Fill="#b2FFFFFF"  Stroke="Red" StrokeThickness="1" />
                </telerik:InformationLayer.HighlightFill>
            </telerik:InformationLayer>

Thanks,

Hi Amit,

Since RadMap shapes like MapPolyline, MapPolygon and etc. does not support context menu out-of-the-box I highly recommend that you use the approach my colleague Andrey demonstrated in this forum post. (as you will see we add the context menu to the RadMap itself and not the Information Layer). I believe that you would be able to find the clicked polygon from MenuItemClicked event args.
