In the scenario below one should be able to access the defined UserData value in the SearchCompleted event handler

How to reproduce:

                }

How to reproduce: change the Windows culture to Greek and start the OSM example

How to reproduce:  
public partial class Form3 : Form
 {
     public Form3()
     {
         InitializeComponent();

         MapLayer pointLayer = new MapLayer("PointG");
         pointLayer.ClusterStrategy = new ElementClusterStrategy();
         pointLayer.ClusterDistance = 100;
         this.radMap1.Layers.Add(pointLayer);

         MapPin pin1 = new MapPin(new PointG(45d, 15d)) { BackColor = Color.Coral, ToolTipText = "Tool Tip1" };
         MapPin pin2 = new MapPin(new PointG(44d, 18d)) { BackColor = Color.Coral, ToolTipText = "Tool Tip2" };
         this.radMap1.Layers["PointG"].Add(pin1);
         this.radMap1.Layers["PointG"].Add(pin2);

         this.SetupProviders();
     }

     private void radMap1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
     {
         MapCluster cluster = sender as MapCluster;
         if (cluster != null && cluster.ClusteredItems.Count == 1)
         {
             cluster.ToolTipText = ((MapPin)cluster.ClusteredItems[0]).ToolTipText;
         }
     }

     private void SetupProviders()
     {
         string cacheFolder = @"..\..\cache";
         BingRestMapProvider bingProvider = new BingRestMapProvider();
         bingProvider.Culture = System.Threading.Thread.CurrentThread.CurrentCulture;
         bingProvider.ImagerySet = ImagerySet.Road;
         bingProvider.UseSession = true;
         bingProvider.BingKey = "...";

         LocalFileCacheProvider cache = new LocalFileCacheProvider(cacheFolder);
         bingProvider.CacheProvider = cache;

         this.radMap1.MapElement.Providers.Add(bingProvider);

         bingProvider.InitializationComplete += bingProvider_InitializationComplete;
     }

     private void bingProvider_InitializationComplete(object sender, EventArgs e)
     {
         this.radMap1.BringIntoView(new PointG(45d, 15d), 5);
     }

 }

Workaround: handle the ToolTipNeededEvent
 private void radMap1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
 {
     MapCluster cluster = sender as MapCluster;
     if (cluster != null && cluster.ClusteredItems.Count == 1)
     {
         cluster.ToolTipText = ((MapPin)cluster.ClusteredItems[0]).ToolTipText;
     }
 }

Until released use the following custom implementation:
public partial class RoadOnDemandForm : RadForm
{
    public RoadOnDemandForm()
    {
        InitializeComponent();

        string cacheFolder = @"..\..\cache";
        BingRestMapProvider bingProvider = new MyBingRestMapProvider();
        bingProvider.Culture = System.Threading.Thread.CurrentThread.CurrentCulture;
        bingProvider.ImagerySet = ImagerySet.Road;
        bingProvider.UseSession = true;
        bingProvider.BingKey = "YourApiKey";

        LocalFileCacheProvider cache = new LocalFileCacheProvider(cacheFolder);
        bingProvider.CacheProvider = cache;

        this.radMap1.MapElement.Providers.Add(bingProvider);
    }
}

public class MyBingRestMapProvider : BingRestMapProvider
{
    private const string ImageryMetadataServiceUri = "https://dev.virtualearth.net/REST/v1/Imagery/Metadata/{set}?output=json&key={key}&c={culture}&dir={directory}";

    protected override void InitializeImageryService()
    {
        typeof(BingRestMapProvider).GetField("tileMetadataInfo", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(this, null);

        try
        {
            string uriString = ImageryMetadataServiceUri;
            uriString = uriString.Replace("{set}", "RoadOnDemand");
            uriString = uriString.Replace("{key}", string.IsNullOrEmpty(this.SessionId) ? this.BingKey : this.SessionId);
            uriString = uriString.Replace("{culture}", this.Culture.ToString());
            uriString = uriString.Replace("{directory}", "0");

            WebClient client = new WebClient();
            client.DownloadStringCompleted += this.InitializeImageryMetadataCompleted;
            client.DownloadStringAsync(new Uri(uriString, UriKind.Absolute));
        }
        catch (Exception ex)
        {
            throw new Exception(string.Format("Imagery Service Exception: {0}", ex.Message));
        }
    }
}

To reproduce: The TileSize property of the LocalMapProvider is readonly.

Workaround:

 public class CustomLocalMapProvider : LocalMapProvider
        {
           
            public CustomLocalMapProvider()
            {
              
                FieldInfo fi = typeof(LocalMapProvider).GetField("tileSize", BindingFlags.Instance | BindingFlags.NonPublic);
                fi.SetValue(this, new Size(200,200));
            }
        }

To reproduce:

set the clustering and add some pins upon a button click.

Workaround

Refresh with the following method:

To reproduce:
1. Add a pin to the map.
radMap1.Layers.Add(new MapLayer("PinLayer"));
MapPin pin = new MapPin(new Telerik.WinControls.UI.Map.PointG(47.60357, -122.32945));
pin.BackColor = Color.Red;
radMap1.Layers[0].Add(pin);
2. Run the project and zoom out.
3. Resize vertically the map(form).

Workaround:
Call Pan method to recalculate RadMapElement.ViewportInPixels on SizeChanged. 
private void RadMap1_SizeChanged(object sender, EventArgs e)
{
    this.radMap1.Pan(this.radMap1.MapElement.PanOffset.Width, this.radMap1.MapElement.PanOffset.Height);
}

Please refer to the sample project and follow the steps:

1. Run the attached application.
2. Hover over the calendar (custom cluster) 
3. Tooltip is shown.
4. Zoom out once 
5. Hover over the calendar.
6. No tooltip is shown - ToolTipTextNeeded is not called.
7. Zoom out once more.
8. Hover over the calendar.
9. No tooltip is shown - ToolTextNeeded is not called.
10. Zoom out once more. Now two icons are shown.
11. Hover over either calendar. 
12. Tooltip is shown.

Recently OpenStreetMap changed their tile usage policy and require UserAgent string in the web headers for accessing tile.openstreetmap.org tiles.

https://operations.osmfoundation.org/policies/tiles/

As a result, standard open street map mode does not work - no tiles are loaded and "too many requests" error is returned from the server.

RadMap's OpenStreetMapProvider needs API (event, property or similar) for easier set up of UserAgent / Referer / other headers of web requests.

 

Hello,

I am using RadMap to display a KML file.

Unfortunately, it looks like RadMap is not displaying properly all the shapes (departments).

Displayed with RadMap (few holes, ie departments not displayed): 

 

Displayed with a third party tool (all departments properly displayed):

I have attached the KML file in a zip file.

 Best,

Olivier
