  • 4 minutes to read

This example illustrates how to customize vector items when they are drawn on a map.

To do this, it's necessary to handle the MapControl.DrawMapItem event and provide new values for the event arguments object.

using DevExpress.XtraMap;

namespace DrawMapItemExample {

    public class MapItemFactory : DefaultMapItemFactory {

        protected override void InitializeItem(MapItem item, object obj) {
            base.InitializeItem(item, obj);
            MapRectangle rect = item as MapRectangle;
            if(rect != null) {
                rect.Width = 1000;
                rect.Height = 1000;
