Accessing doubles in a MobileServiceTable RRS feed

  • Question

  • I have a MobileServiceTable (Azure web mobile service) that I am able to pull data from and then bind particular fields to a list view.

    What I want to do is take some geolocation information in in one of these records/object and pass it through to the map. I am not sure how to identify the doubles in the object and then pass them through to the map when an item in the list is selected, the code I have so far is as follows:


    <Grid Grid.Column="2" Margin="10,10,0,10" x:Name="SelectedUniView">
                <ListView x:Name="shortItems" IsSynchronizedWithCurrentItem="False" SelectionMode="Single">
                            <StackPanel Orientation="Vertical">
                                <TextBlock x:Name="Groups" Text="{Binding Groups}"/>
                                <TextBlock x:Name="Towns" Text="{Binding Town}"/>
                                <TextBlock x:Name="Postcodes" Text="{Binding Postcode}"/>
                                <TextBlock x:Name="WebsiteName" Text="{Binding Website}"/>
                                <HyperlinkButton x:Name="Websites" NavigateUri="{Binding Website}" Content="Go Website" HorizontalAlignment="Left"/>
    bm:Map Credentials="map-key-credentials-are-here" x:Name="myMap"/>


        public class uniworld
            public string Id { get; set; }
            [JsonProperty(PropertyName = "ProviderName")]
            public string ProviderName { get; set; }
            [JsonProperty(PropertyName = "Town")]
            public string Town { get; set; }
            [JsonProperty(PropertyName = "Postcode")]
            public string Postcode { get; set; }
            [JsonProperty(PropertyName = "Groups")]
            public string Groups { get; set; }
            [JsonProperty(PropertyName = "Website")]
            public Uri Website { get; set; }
            [JsonProperty(PropertyName = "Latitude")]
            public double Latitude { get; set; }
            [JsonProperty(PropertyName = "Longitude")]
            public double Longitude { get; set; }
     private void InitializeMap()
                myMap.Center = new Location(shortItems.SelectedValue.Latitude, shortItems.SelectedValue.Longitude);
                myMap.ZoomLevel = 12;
                myMap.MapType = MapType.Road;
    The two areas that are new Locations 'shortItems.SelectedValue.Latitude' is where I am stuck, im thinking that I probably have to some sort of loop to write the values into public doubles, but im hoping there is a more elegant way.

  • SelectedValue and SelectedItem are of type 'object', not 'uniworld'. Try this code:

    uniworld selected = (uniworld)shortItems.SelectedItem;
    myMap.Center = new Location(selected.Latitude, selected.Longitude);
