Cross-Layer Integration

A Walking Tour in Rome

This example demonstrates how to combine all three MapLayer types available in RadMap: Tile, Shape and Marker, to create a complex scenario.

The Shape and Marker layers are data-bound to RadClientDataSource controls by setting the ClientDataSourceID property of the MapLayer. In this example, the RadClientDataSource controls retrieve the data from JSON files - one for the markers and one with a GeoJSON structure for the shapes. You can download the files from the following links:

  • DefaultVB.aspx
  • DefaultVB.aspx.vb
  • Scripts.js
  • Styles.css
