Limited scroll area


This example specifies a rectangular area that confines the map center point:

In Code

<dxm:MapControl x:Name="map">
using DevExpress.Xpf.Map;
  private void Window_Loaded(object sender, RoutedEventArgs e) {
      map.ScrollArea = new DevExpress.Map.MapBounds(
                              new GeoPoint(44.568441, -11.877712),
                              new GeoPoint(36.219329, 4.030490));
      map.CenterPoint = new GeoPoint(40.155242, -2.912869);
      map.ZoomLevel = 4.5;

In Markup

You can also specify the scroll area in markup. Coordinates are written in the following order: x1, y1, x2, y2, where x1, y1 are the top-left point’s coordinates, and x2, y2 are the bottom-right point’s coordinates.

<dxm:MapControl x:Name="map"
                ScrollArea="-11.877712, 44.568441, 4.030490, 36.219329"
                CenterPoint="40.155242, -2.912869"
