google api for address and distance from locations

notice when using the google api for asp.net,

it will display directionpanel which will state the km from source to destination,

im not sure how to get just the km value from the directionpanel div, coming from one city to another.

hi gautham,

                trying to display the response.route to asp.net label in the form, by using this :

 document.getElementById("lbldistance").innerhtml = response.routes[0].legs[0].distance.text;

seems that it does not show value in asp.net label
