How to use Google map in asp.net application


I have developed a user control which contains the Google map related stuffs. So that you can easily integrate the GoolgeMap API in your Asp.Net application without much strain.
Follow the below steps to use this

  1. Download the GoogleMap APIzip file.

  2. Paste the AppCode folder and the usercontrol, asmx and js files in your application.

  3. Now in a webform design view drag the GoogleMapIntegration.ascx usercontrol.You won't be able to see Google Map in design view. Instead, you should see Script Manager as part of this control.

  4. At this point you can run your application and you should be able to see a blank Google Map on your page when you run the application.



Passing Parameters to GoogleMap
You must specify Google Map API Key for this component. You can obtain this key from http://code.google.com/apis/maps/signup.html.

if (!IsPostBack)
{
GoogleMapIntegration.GoogleMapObject.APIKey = "";
GoogleMapIntegration.GoogleMapObject.Width = "800px";
GoogleMapIntegration.GoogleMapObject.Height = "600px";
GoogleMapIntegration.GoogleMapObject.CenterPoint= new GooglePoint("CenterPoint", 43.66619, -79.44268);
GoogleMapIntegration.GoogleMapObject.Points.Add(new GooglePoint("1", 40.65669, -78.45278));
GoogleMapIntegration.GoogleMapObject.Points.Add(new GooglePoint("1", 47.65669, -75.45278));
GoogleMapIntegration.GoogleMapObject.ShowTraffic = true;
GoogleMapIntegration.GoogleMapObject.Directions.ShowDirectionInstructions= true;


You can also use to get direction between addresses as

GoogleMapIntegration.GoogleMapObject.Directions.ShowDirectionInstructions = chkShowDirections.Checked;
GoogleMapIntegration.GoogleMapObject.Directions.HideMarkers = chkHideMarkers.Checked;
GoogleMapIntegration.GoogleMapObject.Directions.PolylineColor = txtDirColor.Text;
GoogleMapIntegration.GoogleMapObject.Directions.PolylineWeight = int.Parse(txtDirWidth.Text);
GoogleMapIntegration.GoogleMapObject.Directions.PolylineOpacity = double.Parse(txtDirOpacity.Text);
//Provide addresses or postal codes in following lines
GoogleMapIntegration.GoogleMapObject.Directions.Addresses.Clear();
GoogleMapIntegration.GoogleMapObject.Directions.Addresses.Add(txtFirstAddress.Text);
GoogleMapIntegration.GoogleMapObject.Directions.Addresses.Add(txtSecondAddress.Text);
GoogleMapIntegration.GoogleMapObject.Directions.Addresses.Add(txtThirdAddress.Text);


So by this user control you can use the above methods to point the google map.

You can also change the image of the Mapper.

Hope this helps!!!
