   {  
     public void SetValue(string value) { Value = value; }  
     public override void HandleMessage(Message message)  
     {  
       base.HandleMessage(message);  
       switch (message.Name)  
       {  
         case "LatLongField:Set":  
           Sitecore.Context.ClientPage.Start(this, "GetLatLong");  
           break;  
         case "LatLongField:Clear":  
           Sitecore.Context.ClientPage.Start(this, "ClearLatLong");  
           break;  
       }  
       if (Value.Length > 0)  
       {  
         SetModified();  
       }  
     }  
     public void ClearLatLong(ClientPipelineArgs args)  
     {  
       Value = string.Empty;  
       SetModified();  
     }  
     public void GetLatLong(ClientPipelineArgs args)  
     {  
       string currentvalue = WebUtil.GetFormValue(ID);  
       if (!string.IsNullOrEmpty(currentvalue))  
       {  
         string latlong = Geocoding.GetLocation(currentvalue);
