Release 2025.1.211 (2025 Q1)

  • Windows11Compact11Dark
  • Windows11Dark
  • Windows11HighContrast

In this scenario, the reported behavior is observed in NET 8. The same behavior is not reproducible in .Net Framework 4.8. When the map is zoomed max out and we try to pan the view, missing tiles appear and the performance is very slow. Additionally, in the output tab of VS, we can observe some exceptions:

In this case, we have 2 providers. The first one is regular OpenStreetMap and the second one with a different ImageURL address is rendered on top. The tile images downloaded from the second provider are transparent. However, this transparency is not respected from the control and the transparent areas are drawn with black color.

In this case, we have missing image tiles while zooming and scrolling the map. When downloading a tile, the internal WebClient is returning an error with the following message: The server committed a protocol violation. Section=ResponseStatusLine. The WebException does not have a Response. This scenario is not handled in code which will lead to missing image tiles. Zooming the same area will reload the missing tiles, but still, it should be handled in the source code.

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

This exception occurs in Net 6. When we have applied LocalFileCacheProvider and there is one file in the cache folder, starting the app will throw the ArgumentOutOfRangeException. A possible solution here is to check if there is one file inside the folder and remove it if there is such.

If you apply 'left' padding to a callout, it wrongly applies to the right side as well.

The RadMap.Layers collection offers several overloads for the HitTest method:

- HitTest(PointG location)
- HitTest(PointL point)
- HitTest(Point location)

However, if the layer is not visible, its IsVisible property is set to false, the HitTest(PointL point) will not return the clicked pin, but the HitTest(PointG point) method will return it. This behavior is not consistent and all overloads should consider whether the layer is visible or not.

Hi,

Please refer. below code...

        void ShowInfoUI()
        {
            var padding = new Padding(0);
            var font = new Font(Font.FontFamily, 8.0f);

            if (T.InfoLayer.IsVisible = cbShowInfo.Checked)
            {
                var overlays = T.PinsLayer.Overlays;

                for (int i = 0; i < overlays.Count; i++)
                {
                    var callout = new MapCallout(overlays[i]) { Font = font, Padding = padding, Text = "1234567", Distance = 5 };

                    T.InfoLayer.Add(callout);
                }
            }
        }

There are 2 layers, InfoLayer (MapCallout) and PinsLayer (MapPins). cbShowInfo controls if MapCallout tobe shown.

If the 'Text' length is less than 8 wrapping happens, and not otherwise. Usually, If Text length is more then wrapping should happen.

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.

There is a noticeable delay after moving the mouse while panning the map. After making a comparison with Open Street Maps and a local provider, it seems that the local provider is slightly slower than the OSM provider. Please refer to the attached gif file. 

After profiling the project, it seems that Image.FromFile for loading the required tile takes most of the time:

With the OSM the tile is loaded by using Image.FromStream and it takes 3 times less time:

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.
