NuGet Package: DevExpress.Win.Map

public InformationDataProviderBase DataProvider { get; set; }

#Property Value

Type Default Description

#Example

This example demonstrates how to allow users to search for a specific place on a map using the Search panel.

To enable searching in the map control, do the following.

  • Create an InformationLayer and add it to the map.
  • Create an instance of the BingSearchDataProvider and assign it to the InformationLayer.DataProvider property.
  • Specify the Bing Maps key using the BingMapDataProvider.BingKey property.

The Search panel appears automatically (since the MapSearchPanelOptions.Visible property value is true by default).

using DevExpress.XtraMap;
using System.Windows.Forms;

namespace ConnectBingSearchProvider {
    public partial class Form1 : Form {
        const string bingKey = "YOUR BING KEY HERE";

        InformationLayer SearchLayer { 
            get {
                return (InformationLayer)mapControl1.Layers["SearchLayer"];
            }
        }

        public Form1() {
            InitializeComponent();

            BingSearchDataProvider searchProvider = new BingSearchDataProvider() { 
                BingKey = bingKey 
            };

            searchProvider.SearchOptions.ResultsCount = 5;

            SearchLayer.DataProvider = searchProvider;
        }      
    }
}
