I am using GoogleMap 6. In older version, I think that was 4.1 or more older, code like following worked but now it is not working.

// Added marker on map

Marker marker = new Marker();
marker.Draggable = true;
marker.Address = fullLocationName;
map1.Markers.Add(marker);

//On button click. Marker is lost.

protected void btnAddLocation_Click(object sender, EventArgs e)
{
    int i = map1.Markers.Count;

    // i is zero here.

}

How to get marker and its lat/long on postback.

Can anybody help? Thanks.
