I use a Google Maps API within IIS outside of my ASP.NET web form application, I need to retrieve the coordinates and return to the previous page of my project.
The problem starts there, I have a 1st page with the form already filled in and below the form I have a button ("edit"), when I click on this button I go to the edit screen that would load all the data on the screen before along with the Google Maps icon.
When I click on the icon it opens the map of Google Maps and inside it has another button to capture coordinate that, when clicked, should return to the page of ("Edit"). But it loses the parameters presented a message missing the parameter such ...
I have tried to retrieve this parameter through the Session, but it does not work. I already tried to pass the parameter through the Map URL and it does not work, I get parameter = undefined. I've tried to get the values of controls from the source page in the same link application on the site ( link ) to no avail.
If someone has an idea or other way that I can solve this problem give me a hint.
