[CLOSED] Adding Google Marker From Code Behind

[dev]

I am trying to add some google markers from code behind with additional method AddMarkers at GMapPanel.cs

[Meta]
[Description("")]
public virtual void AddMarkers(MarkerCollection mc)
{
       this.Call("addMarkers", mc);
}

and then from example.cs, i adding these lines at page_load

protected void Page_Load(object sender, EventArgs e)
        {
            if (!X.IsAjaxRequest)
            {
                Marker m = new Marker();
                m.Lat = 10.1;
                m.Lng = 10.2;
                m.Listeners.Click.Handler = "Ext.Msg.alert('Confirm', String.format('You Clicked {0}', el.id));";

                MarkerCollection mc = new MarkerCollection();
                mc.Add(m);

                CenterMap.AddMarkers(mc);
            }
        }

And my page raise a JsonSerializationException: error Error getting value from 'InnerHtml' on 'System.Web.UI.HtmlControls.HtmlHead'. I think i need to convert mc into json but i don't know how to do.. Please help for this problem

Hi,

You should be able to just populate .Markers collection.

GMapPanel1.Markers.Add(marker);

Yes, thank a lot. It is so simple :)

I'm sorry to reopen this thread. Using

GMapPanel1.Markers.Add(marker);

only works when it is in page_load. My intention is also to create a marker from any other method such as directevents. Is it possible?
