The Regions of France sample (under Map Applications → Regions of France) displays a map of France and the surrounding countries, and demonstrates how different layets can be made visible at different zoom levels. As you zoom in, the Regions layer will color France's provinces, then each province will be divided up as the Departments layer comes into view.

The source code snippets demonstrate assigning different layers to different zoom levels.

C#

// Set the zoom visibility ranges of the Regions Layer.
mapControl1.Layers["Regions"].VisibleFromZoom = 200;
mapControl1.Layers["Regions"].VisibleToZoom = 1000;
mapControl1.Layers["Regions"].LabelVisibleFromZoom = 165;

// Set the zoom visibility ranges of the Departements Layer.
mapControl1.Layers["Departements"].VisibleFromZoom = 400;
mapControl1.Layers["Departements"].VisibleToZoom = 1000;
mapControl1.Layers["Departements"].LabelVisibleFromZoom = 165;

VisualBasic.NET

' Set the zoom visibility ranges of the Regions Layer.
mapControl1.Layers("Regions").VisibleFromZoom = 200
mapControl1.Layers("Regions").VisibleToZoom = 1000
mapControl1.Layers("Regions").LabelVisibleFromZoom = 165

' Set the zoom visibility ranges of the Departements Layer.
mapControl1.Layers("Departements").VisibleFromZoom = 400
mapControl1.Layers("Departements").VisibleToZoom = 1000
mapControl1.Layers("Departements").LabelVisibleFromZoom = 165
