Accessing content of Balloon clicked in Google Earth plugin - c#-4.0

Question

I have a Google earth plug-in and I have made various Placemarks and the balloon using the Winform library in c#. Now, i can see those Placemarks on the map and when i click the placemark, i can see the content i have parsed.
Now, my requirement is that when user clicks the balloon, i want to display the content of that balloon displayed in a text box outside the plug-in.
I am not finding any way where it can be recorded a which Placemark has been clicked and i can access the content of the balloon.
Can anybody help on this?

You should be able to find all the info you need here

Edit:
I am not sure of your approach to show the text in your webpage, try something like this
function addData(text) {
// var TheTextBox = document.getElementById("Mytextbox");
// TheTextBox.value = TheTextBox.value + text;
document.getElementById('Mytextbox').innerHTML = '<p>' + text + '</p>';
// if still having problems, try using an alert to see value of your 'text'
alert(text);
}
another idea - instead of listening for a balloonopening, listen for a click
google.earth.addEventListener(ge.getGlobe(), 'click', placemarkClicked);
function placemarkClicked(event) {
var obj = event.getTarget();
// determine if the user clicked on a Placemark
if (obj.getType() == 'KmlPlacemark') {
event.preventDefault();
var placemark = obj;
var placemark_name = placemark.getName();
var placemark_desc_active = placemark.getBalloonHtmlUnsafe();
// proceed to use the name and description as you like
