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

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:

Release R1 2020

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.

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));
            }
        }

How to reproduce: Check the attached project and video

Workaround: force an update in the MapElement
Public Class RadForm1

    Private bingKey As String = ""
    Dim myTimer As Timer
    Public Sub New()

        InitializeComponent()
        Dim bingProvider As BingRestMapProvider = New Telerik.WinControls.UI.BingRestMapProvider()
        bingProvider.UseSession = True
        bingProvider.BingKey = bingKey

        AddHandler bingProvider.SearchCompleted, AddressOf bingProvider_SearchCompleted

        Me.RadMap1.Providers.Add(bingProvider)

        myTimer = New Timer
        myTimer.Interval = 500
        AddHandler myTimer.Tick, AddressOf OnMyyTimerTick
    End Sub

    Private Function OnMyyTimerTick() As Object
        myTimer.Stop()
        Me.RadMap1.MapElement.InvalidateMeasure(True)
    End Function

    Private Sub bingProvider_SearchCompleted(sender As Object, e As SearchCompletedEventArgs)

        myTimer.Start()

    End Sub
End Class

Is there a way to not allow the map to WrapAround?

Release R3 2019 (LIB 2019.2.819)
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);
}

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

1. Open the demo application >> Map >> Search example.
2. Enter some text and press Enter.
3. Move the mouse a little bit and you will notice the search box looses focus.

Workaround:  this.radMap1.MapElement.SearchBarElement.SearchTextBoxElement.TextBoxItem.LostFocus+=TextBoxItem_LostFocus;

        private void TextBoxItem_LostFocus(object sender, EventArgs e)
        {
            this.radMap1.MapElement.SearchBarElement.SearchTextBoxElement.TextBoxItem.TextBoxControl.Focus();
        }
Declined

A sample for the required functionality:
public void AddMarker(RadMap Map)
{
    SearchRequest r = new SearchRequest();
    r.Query = "Paris, France";
    r.UserData = new Guid();           
    bingProvider.SearchCompleted += BingProvider_SearchCompleted;
    bingProvider.SearchAsync(r);
}

private void BingProvider_SearchCompleted(object sender, SearchCompletedEventArgs e)
{
    //one cannot access the UserData here
}
