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")))

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)
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,
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,
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:
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.'
Please refer to the attached gif file. The sample project together with the sample files of the local provider can be downloaded here: https://1drv.ms/u/s!AnnV2HsINMD_yxDEY2iOWHXn5V9_?e=VurA0N
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.
Best,
Olivier
