-

i create google map coordinates comming database. in table have coordinates points google pointer in asp.net page. wants search name of city have coordinate of search name in db , highlight color in google map have following code fetch db coordinates:

<script type="text/javascript">         var markers = [         <asp:repeater id="rptmarkers" runat="server">         <itemtemplate>                  {                      <%--''<%# getimagefrombyte(databinder.eval(container.dataitem, "image")) %>' '--%>                      "title":"survey",                      <%--   "title": '<%# eval("name") %>',--%>                      "lat": '<%# eval("lat") %>',                      "lng": '<%# eval("long") %>',                      "description": "<div> <img src='' alt='alternate text1' /></div>",                      "image": "<div> <img src='<%#eval("photo")%>' width='150px' alt='picture not available survey' /></div>",                      "name":'<%# eval("name")%>',                      "phonenumber":'<%# eval("phonenumber")%>'                  }     </itemtemplate>     <separatortemplate>         ,     </separatortemplate>     </asp:repeater>     ];     </script>     <script type="text/javascript">          window.onload = function () {             var mapoptions = {                 center: new google.maps.latlng(markers[0].lat, markers[0].lng),                 zoom: 8,                 maptypeid: google.maps.maptypeid.roadmap             };             var infowindow = new google.maps.infowindow();             var map = new google.maps.map(document.getelementbyid("dvmap"), mapoptions);             (i = 0; < 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+data.image+data.name+                             '<br/>'+ data.phonenumber);                          infowindow.open(map, marker);                     });                 })(marker, data);             }         } </script>

to deal issue, first have check if marker present on map or not. use following method know if city under search has latitude , longitude on map or not.

this method return true if coordinates of city under search present on map else return false.

map.getbounds().contains(marker.getposition());

once returns true, can assign color.

hope helps!!
