Hi All,
I am trying to display google map in master page.But map was not loading only empty page was displaying.
Please find my code below:
<asp:Content ID="Content1" ContentPlaceHolderID="Contentplaceholder1" runat="server">
<script type="text/javascript" src = "https://maps.googleapis.com/maps/api/js?key=AIzaSyC6v5-2uaq_wusHDktM9ILcqIrlPtnZgEk&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
alert('here');
var markers = JSON.parse('<%=ConvertDataTabletoString() %>');
var mapOptions = {
center: new google.maps.LatLng(markers[0].lat, markers[0].lng),
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
for (i = 0; i < markers.length; i++) {
var data = markers[i]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})(marker, data);
}
}
</script>
<section id="content">
<body onload="initialize()" onunload="GUnload()">
<div id="map_canvas" style="width: 800px; height: 600px"></div>
</body>
</section>
</asp:Content>
In Sample.aspx.cs code:
public string ConvertDataTabletoString()
{
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection("Server=acysemf4vo.database.windows.net;Database=test;User ID=sa;Password=test;Trusted_Connection=False;Encrypt=True;Connection Timeout=60;"))
{
using (SqlCommand cmd = new SqlCommand("SELECT lat=LATITUDE,lng=LONGITUDE,info.CUSTCODE,description=CUSTNAME FROM table2 INNER JOIN info ON table2.CUSTCODE=info.CUSTCODE and CSTATUS = 0", con))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
Dictionary<string, object> row;
foreach (DataRow dr in dt.Rows)
{
row = new Dictionary<string, object>();
foreach (DataColumn col in dt.Columns)
{
row.Add(col.ColumnName, dr[col]);
}
rows.Add(row);
}
return serializer.Serialize(rows);
}
}
}
Any one can help me on this issues.
Thanks
Krishna
