Property Value

Type Description

A Uri object that specifies the style file’s location.


Use the StyleFileUri property to apply a custom style to vector tiles. Styles apply on a client’s side before rendering the map.

A style must be a valid JSON file. The Map Control supports layers and their properties:

  • filter
  • paint
    • fill-color
    • fill-opacity
    • line-color
    • line-opacity
    • line-width
    • text-color
  • layout
    • visibility
    • text-field
    • text-font
    • text-max-width
    • text-size
    • text-transform

Property values can be set directly (for example, “text-size”: 10) or via an interpolation syntax (for example, “line-width”: {“base”: 1.2, “stops”: [[15, 1], [17, 4]]}).

The following color formats are supported: hsl, rgb, rgba, hsla, hex. You can use web color names, such as red or yellow.

Apply a Style

  1. The MapControl uses the Newtonsoft.Json library to parse style files. Install the Newtonsoft.Json package if your application does not reference this library.
  2. Use the VectorTileDataProviderBase.StyleFileUri property to define a path to a style file.
<dxm:MbTilesDataProvider ... StyleFileUri="D:\Styles\basic-style.json"/>
