Example

This example shows how to use the ListSourceDataAdapter to load shipwreck information from an XML file and display wrecked ship images on a map.

1. Create a ListSourceDataAdapter object and assign it to the VectorLayer.Data property.
2. Specify the DataSourceAdapterBase.DataSource property.
3. Configure the ListSourceDataAdapter.Mappings property to assign data source field values to map items.
4. Use the ListSourceDataAdapter.ItemSettings property to specify map item settings.

MainWindow.xaml

<dxm:VectorLayer.Data>
    <dxm:ListSourceDataAdapter DataSource="{Binding Source={StaticResource data}, XPath=Ship}">
        <dxm:ListSourceDataAdapter.AttributeMappings>
            <dxm:MapItemAttributeMapping Name="Name" Member="Name"/>
            <dxm:MapItemAttributeMapping Name="Year" Member="Year"/>
            <dxm:MapItemAttributeMapping Name="Description" Member="Description"/>
        </dxm:ListSourceDataAdapter.AttributeMappings>
        <dxm:ListSourceDataAdapter.Mappings>
            <dxm:MapItemMappingInfo Latitude="Latitude" Longitude="Longitude"/>
        </dxm:ListSourceDataAdapter.Mappings>
        <dxm:ListSourceDataAdapter.ItemSettings>
            <dxm:MapCustomElementSettings ContentTemplate="{Binding Source={StaticResource itemTemplate}}"/>
        </dxm:ListSourceDataAdapter.ItemSettings>
    </dxm:ListSourceDataAdapter>
</dxm:VectorLayer.Data>

The structure of the XML file used in the example looks as follows:
