Example

How to: Generate Lines from a Data Source

This example demonstrates how to generate map lines based on data source objects and how to display these lines on a vector layer.

1. Create a ListSourceDataAdapter object and assign it to the VectorLayer.Data property.

2. Specify the adapter’s DataSource property.

3. Create a MapLineMappingInfo object and assign to the adapter’s Mappings property.

4. Map the following properties to data source fields:

   • Point1 – Specifies a data field that contains information about the first line point.
   • Point2 – Specifies a data field that contains information about the second line point.
   • Latitude – Specifies a data field that contains point latitudes. (Use the YCoordinate property for Cartesian coordinate systems.)
   • Longitude – Specifies a data field that contains point longitudes. (Use the XCoordinate property for Cartesian coordinate systems.)

5. To specify the type of created map items, you should assign the appropriate settings to the ListSourceDataAdapter.ItemSettings property. In this example, use MapLineSettings to draw lines.
