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.
Currently, the workaround is to override the OpenStreetMapProvider like so:
public class CustomOpenStreetProvider : OpenStreetMapProvider{
public CustomOpenStreetProvider()
{
OpenStreetMapnikSource osmMapInkSource = this.MapSources.Values.ToList()[0] as OpenStreetMapnikSource;
if (osmMapInkSource != null)
{
osmMapInkSource.WebHeaders.Add(System.Net.HttpRequestHeader.UserAgent, "your custom user agent string");
}
}
}
If XML of the KML file is not ordered properly (beautified with tabs and new lines), the AsyncKmlReader doesn't read all shapes.
To work this around, beautify the KML file before passing it to the shape reader.
Zooming in and out LineData objects in Visualization layer can result in some objects disappearing from the viewport or moving to wrong positions.
Visualization layers are removed from the RadMap in a moment when MapShapeData objects are being processes (their geometries are processed). This leads to exception in MapShapeData.cs ' SetLogicalWidth method. Available in R2 2017 SP
When the PathData contains Arc segment which looks as vertical half-circle then it is not displayed in VisualizationLayer.
Map with ItemsSource bound to collection is hosted in RadPane . By closing the pane or by using LoadLayout() of RadPane - NulReferenceException is thrown. Available in LIB version: 2015.1.1603
Map with VisualizationLayer (VL) bound to collection of objects. VL uses an ItemTemplate consisting of MapEllipseView object whose Location Width and Height properties are bound to ViewModel's properties. On a button click, the ItemsSource of the VL is refreshed. However, the ellipses do not appear until a zoom action is performed.
If you update the Location of a map shape data object (for example, EllipseData, PolygonData, ect.) at run-time, while the clustering feature is enabled, the shape disappears.
To work this around, reset the clustering via the IsClusteringEnabled property when the Location changes.
this.ellipseShapeData = new Location(newLatitude, newLongitude);
this.visualizationLayer.ClusteringEnabled = false;
this.visualizationLayer.ClusteringEnabled = true;
Good Afternoon,
we use the RadMap's SelectionRectangleChanged event to allow the user to (de)select map elements with the box. In the event handler we use the layer's GetItemsInRectangle function to see what is within the selected area but this is where we encounter a problem with LineData objects. Dragging a selection rectangle that does not touch an edge but is close enough to it (likely within the bounding box of the LineData) it incorrectly recognizes the line as within the rectangle. See the attached screenshot for an example of a selection rectangle that should contain no elements within but actually reports the long line to its right as an element it contains. This can also be reproduced with the attached project:
- Ctrl + Mouse Left to drag a selection rectangle
- Mouse Left to pan, mouse wheel zo zoom. Shift + Mouse Left for zoom rectangle
- Draw a selection rectangle on the very left or right outside the elements: Debug Output reports "Selected Edges: 0"
- Draw a selection rectangle close to an edge but not touching it: Debug Output reports "Selected Edges: 1"
- Draw selection rectangle that contains (parts of) an edge: Debug Output reports "Selected Edges: 1"

When using MapArcSementView , setting SweepDirection="ClockWise" does not work. The arc is always CounterClockWise.
Map freezes if current culture is non en-US ,AsyncShapeFileReader reads shapes and the Map is zoomed.
MapPath with RotateTransform is added in InformationLayer runtime. Map produces NullReferenceException. As a workaround you can use Visualizationlayer and PathData.
RadMap's VisualizationLayer with ClusterGenerator. The default value of AutoExpandWhenSingle is used - TRUE. When removing items from the cluster at runtime, it does not auto expand when only one item is contained in the cluster. The fix will be available in the internal build from 9.November 2015 as well as in the Q1 2016 official Release.
