InformationLayer binding

[Anton Z]

Hello,

I have an MVVM application.
In this application I use RadMap control with search engine via BingSearchProvider class.
If I binding result of work BingSearchProvider as ObservableCollection<Location> all works perfectly,

<telerik:InformationLayer x:Name="informationLayer"
    ItemsSource="{Binding Path=LocationData.SearchResult}">
 <telerik:InformationLayer.ItemTemplate>
....


public ObservableCollection<Location> SearchResult { get; private set; }

private void geoHelper_SearchCompleted(object sender, LocSearchCompletedEventArgs e)
{
    SearchResult.Clear();

    var searchResult = e.Locations as ObservableCollection<MyMapItem>;
   foreach(MyMapItem loc in searchResult)
       SearchResult.Add(loc.Location);
}

but if I try to wrap result in MyMapItem and try binding ObservableCollection <MyMapItem>
the map refuses to display search result positions on InformationLayer.

<telerik:InformationLayer x:Name="informationLayer"
    ItemsSource="{Binding Path=LocationData.SearchResult.Location}">
 <telerik:InformationLayer.ItemTemplate>
....

public class MyMapItem
{
    public Location Location
    {
        get;
        set;
    }

    public string Title
    {
        get;
        set;
    }

    public string Description
    {
        get;
        set;
    }
}

public ObservableCollection<MyMapItem> SearchResult { get; private set; }

private void geoHelper_SearchCompleted(object sender, LocSearchCompletedEventArgs e)
{
    SearchResult.Clear();

    var searchResult = e.Locations as ObservableCollection<MyMapItem>;
   foreach(MyMapItem loc in searchResult)
      SearchResult.Add(loc);
}

How i can solve this problem? How i can use custom class for display position on Radmap control? I don't want use buffer object list =(

Here is located the simple project which demonstrate a problem

Hi Anton Z,

You should use the DataMappings on the InformationLayer class. With them you can indicate which property contains the Loction, Latitude or Longitude. Check this example for more info.
