Google Map in C#

Nov 11th, 2009

I am trying to develp a webpage that takes in TO and FROM Addres and displays the Google Map as well the directions.
I understand JScript helps out with the Google Map display and I played around with the URL google.maps.com to get the directions. Now my issue is I have to pass on the data from the C# to JScript and i m struck here..

Use GMap asp.net control.

SUMMARY: A custom server control wrapper for the Google Maps API. Developed for ASP.Net using C#, JavaScript, and XSL. The GMap control makes using Google Maps easy for .Net developers; allowing them to interact with Google Maps using standard .Net language

Take a look at an article - http://www.codeproject.com/KB/custom...lat-Part1.aspx
