Distance Related Search Google API

[wilberforce2]

Hello

I am new to ASP.net 2.0 and I am having some problems creating a distance related search in a directory.

I am using the following code to get Latitude and longitude data from google maps from a postcode a user types in to perform a search. The problem I am having is that to use the showAddress function I must call it with return false but this prevents the form posting and the search being imitated. Any ideas in how I can solve this issue. I have looked everywhere on the web and cannot find any examples. I am using Visual Web Studio Express Edition. The database already has the Latitude and longitude details for each entry. I can post the full code if it’s required.

Thanks

   <script type="text/javascript">
    var map = null;
    var geocoder = null;

    function initialize() {
      if (GBrowserIsCompatible()) {
        map = new GMap2(document.getElementById("map_canvas"));
        geocoder = new GClientGeocoder();
      }
    }

  function showAddress(address) {
  
      if (geocoder) {
      alert("GeoCode")
        geocoder.getLatLng(
          address,
          function(point) {
            if (!point) {
              alert(address + " not found");
            } else {
              map.setCenter(point, 13);
              alert(point.y)
              //document.getElementById("DetailsView1_LatTextbox").value = point.y
              //document.getElementById("DetailsView1_LonTextbox").value = point.x
            }
          }
        );
      }
    }
       
    </script>

OnClientClick="showAddress(document.getElementById('TextBox1').value); return false" />

you're attempting to mix client and server code. if you don't/can't use a full postback then you have 2 options:
1. use an ms ajax updatepanel to create a ajax call.
2. create a web serivce which executes the search and returns the results in xml/json format. parse on client and display.

depending on how your page functions may dictate if either option is viable.
