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.

The ShapeFileReader fails in its ReadDbfRecord method:

            using (MemoryStream shapeStream = new MemoryStream(File.ReadAllBytes(@"C:\Users\dyordano\Downloads\84aa4699-f436-4b7e-b029-e353fdab0411_shapefile-before-modification\asseuappareil.shp")))
            {
                using (MemoryStream dbfStream = new MemoryStream(File.ReadAllBytes(@"C:\Users\dyordano\Downloads\84aa4699-f436-4b7e-b029-e353fdab0411_shapefile-before-modification\asseuappareil.dbf")))
                {
                    ShapeFileReaderParameters parameters = new ShapeFileReaderParameters();
                    parameters.ShapeStream = shapeStream;
                    parameters.DbfStream = dbfStream;
                    ShapeFileReader reader = new ShapeFileReader();
                    List<MapVisualElement> elements = reader.Read(parameters);
                }
            }

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.

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:

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

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.

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

Run the attached project and follow the steps in the gif file. As a result the following exception occurs:

System.IO.IOException: 'The process cannot access the file 't_0_0_1.png' because it is being used by another process.'
