SpotGnome.com - ASP.NET Google Map Control

Wednesday, January 09, 2008

If you are looking for a ASP.NET Google Map Control, your search is now over.

Jacob Reimers from http://www.reimers.dk/ offers a great asp.net control in 2 flavors.

The free version which lets you easily display a map with markers and/or lines and a licensed version which gives you the full power of Google Maps.

Download the free control, unzip it to your Bin folder in your web app and add a reference to it.

This is a sample asp.net page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="GoogleMap" Namespace="Reimers.Map" TagPrefix="Reimers" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Google Map test</title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <reimers:googlemap id="GMap" runat="server" width="349" height="354" onmarkerclick="GMap_MarkerClick" />
        </div>
    </form>
</body>
</html>

and the code behind:

using System;
using System.Web.UI;
using Reimers.Map;
 
public partial class _Default : Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        GMap.GoogleKey = "Your API Code here";
        GMap.MapType = MapType.Map;
        GMap.TypeControl = MapTypeControl.None;
        GMap.MapControl = ControlType.Small;
 
        GoogleMarker testMarker = new GoogleMarker("newMarker", new GoogleLatLng(43.611611, -88.952931));
        testMarker.MarkerText = "Test Marker";
        GMap.Markers.Add(testMarker);
 
        GMap.Latitude = testMarker.Latitude;
        GMap.Longitude = testMarker.Longitude;
        GMap.Zoom = 10;
    }
 
    protected void GMap_MarkerClick(GoogleMap GMap, GoogleMarker Marker, ref String MapCommand)
    {
        MapCommand = Marker.OpenInfoWindowHTML(GMap, Marker.MarkerText);
    }
}
