Re: google maps not working

hmm...I'm not too sure what you mean by that, but maybe let me explain to you what i want to achieve.

within this code, now I can get the correct address shows up on the google map, however if the address is invalid (e.g. 123 test street, new york). then the map will not show up. my question is how can i modify the code, so that when the address is invalid, it will popup an alert saying "address not found on map", or else it will show the correct address in the map.

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

function load()
{
    var address = document.getElementById("<%=lblmap.ClientID%>").innerHTML;
    map = new GMap2(document.getElementById("map"));
    geocoder = new GClientGeocoder();
    geocoder.getLocations(address, addToMap);
}

function addToMap(response)
{
        place = response.Placemark[0];
        point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]);
        map.setCenter(point,13);
        marker = new GMarker(point);
        map.addOverlay(marker);
        marker.openInfoWindowHtml(place.address);
}
</script>

I tried to learn from your sample3 to do the "IF" statement, but I don't know which value to use as condition. I can only imagine "IF" the address is invalid, alert the error message, else load the map correctly.

I tried this, but doesn't seems to be getting it right.

<script type="text/javascript" language=javascript>		
var geocoder;		
var map;				
function load()		
{			
  var address = document.getElementById("<%=lblmap.ClientID%>").innerHTML;			
  map = new GMap2(document.getElementById("map"));			
  geocoder = new GClientGeocoder();			
  geocoder.getLocations(address, addToMap);		
}				

function addToMap(response)		
{	
  if(response >= 0)
  {			
    place = response.Placemark[0];				
    point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]);				
    map.setCenter(point,13);				
    marker = new GMarker(point);				
    map.addOverlay(marker);				
    marker.openInfoWindowHtml(place.address);	  
  }
  else 
  {
    alert("address not found on map");
  }
}		
</script>

The result is it always get popup the alert, even if the address is valid. however the address never shown up on the map when the address is valid.

what can i do to make the if statement work? Please kindly help.

finally, I sort of got it working, although I don't think it is the best practice. my next question is i want to create a button, when click the button, it passes the address and opens up a new page with google map ONLY and its controls. this is for user to have full control over the map. Can someone please show me how to achieve this?

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

			
			function load()
			{
				var address = document.getElementById("<%=lblmap.ClientID%>").innerHTML;
				map = new GMap2(document.getElementById("map"));
				map.addControl(new GSmallMapControl());
				geocoder = new GClientGeocoder();
				geocoder.getLocations(address, addToMap);
			}
			
			function addToMap(response)
			{
				if (response.Placemark != null)
				{
					place = response.Placemark[0];
					point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]);
					map.setCenter(point,16);
					marker = new GMarker(point);
					map.addOverlay(marker);
					marker.openInfoWindowHtml(place.address);
				}
				else
				{
					alert("Sorry, map not available");
				}
			}
			</script>

Also you place

var element = document.getElementById("map");
if(element)
map=new GMap2(element);

Instead of

In computer science, an application programming interface (API) is an interface that defines the ways by which an application program may request services from libraries and/or operating systems.[1][2][3] An API determines the vocabulary and calling conventions the programmer should employ to use the services. It may include specifications for routines, data structures, object classes and protocols used to communicate between the requesting software and the library.

When used in the context of web development, an API is typically a defined set of Hypertext Transfer Protocol (HTTP) request messages along with a definition of the structure of response messages, usually expressed in an Extensible Markup Language (XML) or JavaScript Object Notation (JSON) format. While "Web API" is virtually a synonym for web service, the recent trend (so-called Web 2.0) has been away from Simple Object Access Protocol (SOAP) based services towards more direct Representational State Transfer (REST) style communications[5]. Web APIs allow the combination of multiple services into new applications known as mashups [6].

Problem displaying Windows Control in ASP.net Web Site.

Hello, This is Vikash.

I am facing problem displaying the windows control created by me in ASP.net web site.

Actually, I am totally new to this and haven't done this thing before.

But after searching some article on the web i have created a small windows control with 2 textboxes and a Command button. When the button is clicked it copies the text in textbox1 to textbox2.

This is the Code of my User Control:

Imports System
Imports System.Windows.Forms
Imports System.Runtime.InteropServices

Public Class Copytext

      Public Sub New()
            ' This call is required by the Windows Form Designer.
            InitializeComponent()
            ' Add any initialization after the InitializeComponent() call.
      End Sub

      Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
            TextBox2.Text = TextBox1.Text
      End Sub
End Class

When I run the project of User Control, it runs fine.

Next I Created a web site in the same Solution and pasted the DLL file of UserControl in the roor directory and then using OBJECT tag embed the control in Web Page.

Code for WebPage is as follows:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
      <title>Untitled Page</title>
</head>
<body>
      <form id="form1" runat="server">
      <div>
   <object id="MyX" classid="WindowToWeb.dll#WindowToWeb.Copytext" style="width: 312px; height: 160px"></object>
      </div>
      </form>
</body>
</html>

But when i run the web page it displays just a blank box.

can someone please tell me or guide me in this matter.

Any help would be greatfull.

Thanks in Advance.

Hi,

Good Day!

In my ASP.NET MVC application, I have 2 dropdown lists.
First one with 2 items namely A.P. & U.P.
When I select an item in the dropdown list, second dropdown list should be populated with corresponding cities in that state. Cities names should be retrived from a table in SQL Server 2005 database.

Your help will be very much appreciated.

Thank you,
Raju

Enable postback to true of DropDownlist1 and on selectedindexchange event of first dropdownlist1 select data from table and populate second dropdownlist.

example:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)<br />
    {<br />
     <br />
           SqlDataSource1.SelectCommand="select * from cities where idcity="+dropdownlist1.SelectedValue;<br />
                DropDownList2.DataSourceID = "SqlDataSource1";<br />
                dropDownList2.DataValueField = "IDCity";<br />
                dropDownList2.DataTextField = "CityName";<br />
                dropDownList2.DataBind();<br />
}
