Getting the same error. I am very interested in a fix for this.
It only happens inside an updatepanel not outside.

Created Unassigned: Markers collection no longer accessible via javascript [14400]

rcbrown — Mon, 22 Apr 2013 14:49:02 GMT

We are trying to open an info window from outside of the map. We used to be able to do this with the following:

var marker = GMap1.Markers[index];
marker.openDefaultInfoWindow();

However now I cannot figure out how to access the marker collection. I see the namespace has changed to maps.GMap1.. but I cannot find the marker collection in any of the properties of this object. Is there any way to achieve this? Thank you in advance,

Created Unassigned: Enum mismatch [14399]

wpq0 — Mon, 22 Apr 2013 06:07:48 GMT

Hi,
The most recent version of Google Map JS API changed the "enum" for control positions, the values now start from 1 instead of 0 like before:
{
TOP_LEFT: 1,
TOP_CENTER: 2,
TOP: 2,
TOP_RIGHT: 3,
LEFT_CENTER: 4,
LEFT_TOP: 5,
LEFT: 5,
LEFT_BOTTOM: 6,
RIGHT_TOP: 7,
RIGHT: 7,
RIGHT_CENTER: 8,
RIGHT_BOTTOM: 9,
BOTTOM_LEFT: 10,
BOTTOM_CENTER: 11,
BOTTOM: 11,
BOTTOM_RIGHT: 12,
CENTER: 13
}

Current definition:
{
TopLeft = 0,
...
}

MapControlStyle changed as well:
{
DEFAULT: 0,
HORIZONTAL_BAR: 1,
DROPDOWN_MENU: 2
}

Current definition:
{
Default,
DropdownMenu,
HorizontalBar
}

Hi, Tgaud!

I'm not an expert in using this Artem:GoogleMap control. In fact I started using it last week.

But, as previously written, I don't believe you'll be able to use both in your page. I think you should dig a little more in Artem:GoogleMap control and verify wether there's already something to accomplish the things you have in your javascript code. Take a look at this link.

Hope this help.

Sorry we misunderstood.
But The googleMap control is working..... alone.

And my custom javascript code (google autocompletion of addresses, on textbox) is working, alone.
using

 "https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"

("libraries=places" at the end, is important)

but when I put both together on the same page... nothing works anymore.

pauloric — Tue, 05 Mar 2013 18:06:13 GMT

Hi, Tgaud!

I'm not 100% sure, but I do believe that as you want to use Artem:GoogleMap control you must delete the script you already have in your page.

You should have something like this:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm2.aspx.vb" Inherits="GoogleMaps_SubGurim.WebForm2" %>
<%@ Register assembly="Artem.Google" namespace="Artem.Google.UI" tagprefix="artem" %>
<!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>GoogleMaps - Using Artem Control</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnableScriptGlobalization="true" EnableScriptLocalization="true" />
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <div id="divMap" runat="server" visible="false">
                    <artem:GoogleMap ID="GoogleMap" runat="server" Width="952px" Height="230px"/>
                </div>
            </ContentTemplate>
        </asp:UpdatePanel>    
    </div>
    </form>
</body>
</html>

And, in code-behind (VB), you should have something like this:

Imports Artem.Google.UI

Public Class WebForm2
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim lat As Double = -22.5322
        Dim lng As Double = -44.635899999999999
        Dim marcaTorre As New Marker
        Dim posicao As New LatLng(lat, lng)
        marcaTorre.Icon = "../Imagens/Torre_PR.png"
        marcaTorre.Position = posicao
        GoogleMap.Center = posicao
        GoogleMap.Key = "YourGoogleMapKey"
        GoogleMap.EnableScrollWheelZoom = True
        GoogleMap.EnableMapTypeControl = True
        GoogleMap.Zoom = 15
        GoogleMap.Markers.Add(marcaTorre)
    End Sub

End Class

Hope this help you.

Plz, my project is frozen on this.
I really need that little help, that little moment of your time.

New Post: All runtime setting lost on Postback.

Begust — Mon, 04 Mar 2013 15:51:20 GMT

I am using the 6.1 control.
All setting made during pageload, like Latitude, Longitude, Zoom, and Marks are lost on a postback.
If I set the same setting during page design then each value is remembered.

My example has a map and a button. The map location, zoom and one mark are set during page load, the button click is just moving the location. On button click everything is gone!

Could someone tell me what I'm doing wrong.

Here is my code:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebApplication2._Default" %>

New Post: Error: Object expected- Version 6 control

pauloric — Mon, 04 Mar 2013 13:47:43 GMT

Hi,

Something very weird is happening. First I've tried using this control on a very simple form. Just a Button and the Artem:GoogleMap control inside a <div> that has its Visible property set to false. The idea is to show the map, according to latitude and longitude parameters that are obteined when the button is clicked. I've accomplished this with the following code:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm2.aspx.vb" Inherits="GoogleMaps_SubGurim.WebForm2" %>
<%@ Register assembly="Artem.Google" namespace="Artem.Google.UI" tagprefix="artem" %>
<!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>GoogleMaps - Using Artem Control</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnableScriptGlobalization="true" EnableScriptLocalization="true" />
        <asp:Button ID="Button1" runat="server" Text="Show map" />
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <div id="divMap" runat="server" visible="false">
                    <artem:GoogleMap ID="GoogleMap" runat="server" Width="952px" Height="230px"/>
                </div>
            </ContentTemplate>
        </asp:UpdatePanel>    
    </div>
    </form>
</body>
</html>

The code-behind is as following:

Imports Artem.Google.UI

Public Class WebForm2
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim lat As Double = -22.5322
        Dim lng As Double = -44.635899999999999
        Dim marcaTorre As New Marker
        Dim posicao As New LatLng(lat, lng)
        marcaTorre.Icon = "../Imagens/Torre_PR.png"
        marcaTorre.Position = posicao
        GoogleMap.Center = posicao
        GoogleMap.Key = "myGoogleAPIKey"
        GoogleMap.EnableScrollWheelZoom = True
        GoogleMap.EnableMapTypeControl = True
        GoogleMap.Zoom = 15
        GoogleMap.Markers.Add(marcaTorre)
        divMap.Visible = True
    End Sub
End Class

In this case the webform is not attached to any Masterpage and it works pretty fine, as desired. When button is clicked the map is shown.

So I've became encouraged to move on and use in my web application. This web application has a MasterPage. The webform in which I'm using the Artem Control has a few <div>tags that are shown (or not) depending on some conditions (doesn't matter) and has also a UpdatePanel. So, as in the simple application before, I have the Artem Control inside a <div> tag that has its Visible property set to false. And, also, there's a button that must be clicked to the map be showed. But in this scenario, things don't work. When I click the button (to show the map) I get this error:
return a?new google.maps.LatLng(a.lat,a.lng):null

The Source for my application is as following:

<%@ Page Title=".: Análise de Falhas em LTs - DRN.O :." Language="vb" AutoEventWireup="false" MasterPageFile="~/Site.Master" CodeBehind="frmAnaliseFalha.aspx.vb" Inherits="Interface_Web.frmAnaliseFalha" %>

                    </tr>
                </table>
            </div>
            <div id="divMap" runat="server" visible="false" style="border-bottom: 1px solid #496077; border-left: 1px solid #496077; border-right: 1px solid #496077; padding-top: 3px; text-align: center; border-bottom: 3px;">
                <artem:GoogleMap ID="mapaTorre" runat="server" Width="952px" Height="230px"/>
            </div>
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>

The code-behind for the button is:

    Private Sub btnMapa_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnMapa.Click

        Dim lat As Double = -22.3355 
        Dim lng As Double = -44.453 
        Dim posicao As New LatLng(lat, lng)
        Dim marcaTorre As New Marker
        marcaTorre.Icon = "../Imagens/Torre.png"
        marcaTorre.Position = posicao
        mapaTorre.Center = posicao
        mapaTorre.Key = "my GoogleMaps API key"
        'mapaTorre.EnableScrollWheelZoom = True
        mapaTorre.EnableMapTypeControl = True
        mapaTorre.Zoom = 15
        mapaTorre.Markers.Add(marcaTorre)
        divMap.Visible = True
    End Sub

Of course I have Imports Artem.Google.UI in the code behind as well.

Why does it work in the simple application and does not in my application? It's driving me crazy for many days.

Thanks for your attention.
