Hi
We would like to use vector tiles in our offline mapping applications, like ones you can get here :- https://openmaptiles.com/downloads/dataset/osm/europe/great-britain/england/#5.03/52.946/-2.426
I think telerik only supports raster files right now. Is there any plans to support vector files in the future? Could it be added to the roadmap?
(I am not looking for a way to convert vector files into PNG/Bitmap/JPEG Image tiles in a custom provider thanks)
In the scenario below one should be able to access the defined UserData value in the SearchCompleted event handler How to reproduce: protected override void OnLoad(EventArgs e) { base.OnLoad(e); this.radMap1.ShowSearchBar = true; BingRestMapProvider bingProvider = this.radMap1.Providers[0] as BingRestMapProvider; this.radMap1.MapElement.SearchBarElement.SearchProvider = bingProvider; this.radMap1.MapElement.SearchBarElement.SearchProvider.SearchCompleted += BingProvider_SearchCompleted; } private void BingProvider_SearchCompleted(object sender, SearchCompletedEventArgs e) { Telerik.WinControls.UI.Map.RectangleG allPoints = new Telerik.WinControls.UI.Map.RectangleG(double.MinValue, double.MaxValue, double.MaxValue, double.MinValue); this.radMap1.Layers["Pins"].Clear(); foreach (Telerik.WinControls.UI.Map.Bing.Location location in e.Locations) { Telerik.WinControls.UI.Map.PointG point = new Telerik.WinControls.UI.Map.PointG(location.Point.Coordinates[0], location.Point.Coordinates[1]); MapPin pin = new MapPin(point); pin.Size = new System.Drawing.Size(20, 40); pin.BackColor = Color.Red; pin.ToolTipText = location.Address.FormattedAddress; this.radMap1.MapElement.Layers["Pins"].Add(pin); allPoints.North = Math.Max(allPoints.North, point.Latitude); allPoints.South = Math.Min(allPoints.South, point.Latitude); allPoints.West = Math.Min(allPoints.West, point.Longitude); allPoints.East = Math.Max(allPoints.East, point.Longitude); } if (e.Locations.Length > 0) { if (e.Locations.Length == 1) { this.radMap1.BringIntoView(new Telerik.WinControls.UI.Map.PointG(e.Locations[0].Point.Coordinates[0], e.Locations[0].Point.Coordinates[1])); } else { this.radMap1.MapElement.BringIntoView(allPoints); this.radMap1.Zoom(this.radMap1.MapElement.ZoomLevel - 1); } } else { RadMessageBox.Show("No result found for the provided search query!"); } } Telerik.WinControls.UI.Map.Bing.SearchRequest request; private void radButton1_Click(object sender, EventArgs e) { Telerik.WinControls.UI.MapLayer pinsLayer = new MapLayer("Pins"); this.radMap1.Layers.Add(pinsLayer); request = new SearchRequest(); request.Query = "San Marino"; request.SearchOptions.Count = 10; request.SearchOptions.QueryParse = true; request.UserData = "Tooltip"; BingRestMapProvider bingProvider = this.radMap1.Providers[0] as BingRestMapProvider; bingProvider.SearchAsync(request); } Workaround: if possible cache the data to be accessed at a later stage
To reproduce: - Create a shape with QGIS and add it to RadMap using the approach described in the documentation: http://docs.telerik.com/devtools/winforms/map/file-readers/esri-shapefile-reader

In WPF this is possible with custom provider: https://www.telerik.com/forums/map-control-and-web-map-service

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
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.
Hi Team,
Are there any intermediate zoomlevel in the RadMap object?
Currently the transition from one zoomlevel to another is too important.
Thank you for your response
Please refer to the sample project and follow the steps:
1. Run the attached application.
