Example

To provide data from a list source.

1. Create a ListSourceDataAdapter object and assign it to the VectorLayer.Data property.
2. Specify the DataSourceAdapterBase.DataSource property of the object.
3. Specify mappings to data source fields to assign these field values to the adapter-generated map items. To do this, configure the ListSourceDataAdapter.Mappings property.
4. Specify the settings of the adapter-generated map items. To do this, customize the ListSourceDataAdapter.ItemSettings property of the object.
