This is to better address issues with missing pbf files for certain zoom levels. 
Default behavior - scaling cached map images form lower levels - could result in blurry images.
Wanted behavior - rescale lower zoom level pbf files resulting in higher quality images.

The RadMap control does not display the MBTiles file format.
Last Updated: 20 Oct 2023 14:01 by ADMIN

When the VisualizationLayer is populated with FrameworkElement objects (often through the ItemTemplate) and the MapLayer.Location value of a FrameworkElement is updated at runtime, the element itself is not moved to the new location. This happens only if the FrameworkElement is outside of the viewport during the location change action.

To work this around, on location change, remove the data element from the ItemsSource and add it again.

The ZIndex property change is not detected by the VisualizationLayer at runtime. 

Workaround: remove and then add back the item where the ZIndex is changed.

Adding big-sized FrameworkElements in VisualizationLayer and then zooming in might result in disappearing of the element although it should cover the whole or large part of the viewport.

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
  1. Draw a selection rectangle on the very left or right outside the elements: Debug Output reports "Selected Edges: 0"
  2. Draw a selection rectangle close to an edge but not touching it: Debug Output reports "Selected Edges: 1"
  3. Draw selection rectangle that contains (parts of) an edge: Debug Output reports "Selected Edges: 1"

With some projections or rectangles with really small sizes close to 0, LocationRect's ZoomLevel returns incorrect value - int.MinValue. The returned value should always be positive integer.

Add an event that allows you to listen for tiles download finished on the provided. The event should fire only after all tiles for the current viewport are downloaded.

after setting the `ZoomStep` in our project to something smaller than 1 (a feature we are very pleased to receive in the latest update) we encountered a problem when zooming in and out of our map view. I have attached screenshots and an example project to reproduce the issue. It occurs wether the renderer is set to SoftwareOnly or default.

Steps to reproduce:

  1. Start the example project (MapZoomInitial.png)
  2. Scroll the mouse wheel one click in to zoom in one step
  3. Scroll the mouse wheel one click out to zoom out again
  4. Artifacts appear (MapViewAfterZoomInAndOut.png)

When RadMap is in DataTemplate / ControlTemplate of other control and its ZoomLevel (or the new Zoom) property is bound to ViewModel's property, the binding is broken by internal setting of the ZoomLevel/Zoom property and the expected ViewModel property is not set successfully.

With the current implementation of the RadMap control, the default value which will be used for connecting in the internal services is "http". This causes the tiles to not be retrieved if the firewall allows only "https".
