Hello,

on a german Windows, when searching with the bingmapsprovider for "München",

the tooltip on the Pin doesn't shows the ü in the correct way.

Hi,

An exception is thrown while adding layers without name. (System.InvalidOperationException: 'A layer with the same Name already exists in the collection.')

i.e

            var layer1 = new MapLayer();
            var layer2 = new MapLayer();

            map.Layers.Add(layer1);
            map.Layers.Add(layer2);

The simple fix is to always pass a unique name, but it must work like say DataTable.Columns.Add(); (which internally generates unique name)

Thanks

Hi,

Please refer attached screen.

In a specific use case, it was required to add MapPins to a MapLayer, and later MapLayer to be added to a RadMap, and this exception.

Thanks

Use the custom implementation in the following KB article: https://docs.telerik.com/devtools/winforms/knowledge-base/radmap-export-to-an-image?_ga=2.41263138.1402359144.1621138970-937174403.1607349180

The pins are successfully exported in version 2021.1.204:

After upgrading to version 2021.2.511, the pins are not exported anymore:

Run the attached project.
Expected: 
10 points on each row.
Actual:
There is a seemingly random number of points on each row:

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 

To reproduce: add a RadMap with a Bing provider, select the canvas "Aerial with labels on demand" and zoom in all the way. It always gets the following exception:

System.ArgumentException: Parameter is not valid.
   at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)
   at Telerik.WinControls.UI.MapTileDownloader.TileDownloadDataCompleted(Object sender, DownloadDataCompletedEventArgs e)
   at System.Net.WebClient.OnDownloadDataCompleted(DownloadDataCompletedEventArgs e)

The issue is reproducible in Demo application with the Bing examples.

Workaround:

        public RadForm1()
        {
            InitializeComponent();

            string cacheFolder = @"..\..\cache";
            BingRestMapProvider bingProvider = new Telerik.WinControls.UI.BingRestMapProvider();
            bingProvider.TileDownloader = new CustomMapTileDownloader();
            bingProvider.UseSession = true;
            bingProvider.BingKey = "your bing key";
            LocalFileCacheProvider cache = new LocalFileCacheProvider(cacheFolder);
            bingProvider.CacheProvider = cache;
            this.radMap1.Providers.Add(bingProvider);
             
        }

        public class CustomMapTileDownloader : MapTileDownloader
        {
            protected override void TileDownloadDataCompleted(object sender, System.Net.DownloadDataCompletedEventArgs e)
            {
                TileInfo tileInfo = ((TileInfo)e.UserState);

                if (e.Error == null)
                {
                    try
                    {
                        using (MemoryStream ms = new MemoryStream(e.Result))
                        {
                            Image img = Image.FromStream(ms, true, true);
                            tileInfo.Content = e.Result;

                            this.OnTileDownloadComplete(new TileInfoEventArgs(tileInfo));

                            lock (this.webClientsPoolLockObject)
                            {

                                this.webRequestCache.Remove(tileInfo.Quadkey);
                            }
                        }
                    }
                    catch (Exception)
                    {
                        
                        
                    }
                           
                    
                }
                else
                {
                    if (this.ShouldRetryDownload(e.Error))
                    {
                        Uri uri = this.webRequestCache[tileInfo.Quadkey];

                        lock (this.webClientsPoolLockObject)
                        {
                            uri = new Uri(this.webClientsPool[tileInfo.Quadkey].BaseAddress);
                            this.webClientsPool[tileInfo.Quadkey].DownloadDataCompleted -= this.TileDownloadDataCompleted;
                            this.webClientsPool.Remove(tileInfo.Quadkey);
                            this.webRequestCache.Remove(tileInfo.Quadkey);
                        }

                        this.BeginDownloadTile(uri, tileInfo);
                    }
                }
            }
        }
    }

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.

I have noticed in the routing there is no maxSolutions parameter available when querying the bing map api routing parameter.

Please refer to the sample project and follow the steps:

To reproduce:

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