Social Networking :: How To Show Multiple Markers On Google Maps From Database
Feb 28, 2013
I've a scenario in my website where there is a search page.
When the user fills the search criteria and submits the search button , a Google map will be displayed with a pin depicting the addresses listed by the returned records.
I want to display data from database in GeoMap. My database table is:
Station Name Danger Levels St-01 Normal(blue) St-02 Danger(red) St-06 Warning(yellow) St-10 Danger(red) St-11 Warning(yellow)
Now in GeoMap, For Particular state(of Malaysia), I need to show the different stations and danger level(using colors defined in above table) related to each stations (from above database table). Need to understand the code as per my requirement: URL...
I am looking for multi marker google map from sql server database, I have following code with me which is working perfectly fine but instead of fetching data from sql server it is fetching from xml. How can bind it from sql server to show multi marker.
xml data
<markers> <marker address="630 LAS GALLINAS, San Rafael CA"/> <marker address="2ND ST, Novato CA"/> <marker address="2402 SIR FRANCIS DRAKE BLVD, fairfax CA"/>

i want to include google maps API into my ASP.NET page and allows users to input the locations(few places) they are going to visit. When the user inserts the location, the google maps API will mark these locations. It means in the maps it will mark the places. some red bubble to indicated the places is marked.
for example,i list a few checkboxes beside the check boxes will have a places'name. when the checkbox is checked, Google maps will make markers on these location. How to do this?
IF after the places is marked in google maps, i want to get some information from google maps (such as the coordinates of the all the marked place). Then, use google maps to run some code behind to find the shortest path using Travelling Salesman Problem (TSP) algorithm.
After that,generate the proper sequences of the places ( which place to go first, and which place to go last). is it possible to be done?

In above C# code, I want to change the color of DataTable row "Upstream" based on If condition from code behind. I tried below code, but its not working:
decimal res = Convert.ToDecimal(Upstream); if (res <= 0 && res >= 2) { Color col = ColorTranslator.FromHtml("#0000FF"); Upstream = Color.Blue; } else { Color col = ColorTranslator.FromHtml("#FFFFFF"); Upstream = Color.Red; }
I have a scenario where, when user searches for a particular program a list of possible programs should be displayed from database and show it on google map with google markers depicting those addresses. I have achieved it successful with your answer ASP.Net: Populate Google Maps V3 with Multiple Markers using Address Latitude and Longitude values stored in database
Now my question is how can we display those markers with numbers and show the address corresponding to that number in listview.

I used a Google Maps Distance Finder API that comes with two textboxes, one for the source, and one for the destination. It also comes with a button, that when clicked, will find the distance between the two locations using the funciton GetDistance(). The code before the function initializes the map. I created another button and used VB.Net to run SQL code first, and then to automatically populate the two textboxes, then I had it call the function GetDistance().
The issue I ran into is that the function won't calculate the distance, and the map never changes from its default state. I believe it's because it's not running the code that initializes the map. (I could be wrong) I have tried WebBrowser1, to call the click of the button, but I had to Inherit Forms, which I can't do, and I have also tried adding the top code into the GetDistance() function. Is it possible to call the initializing code before GetDistance()?
Here is the JS function code:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places"></script> <script type="text/javascript"> var source, destination; var directionsDisplay; var directionsService = new google.maps.DirectionsService(); google.maps.event.addDomListener(window, 'load', function () {

Here is the VB Code I use to call the JS Function:

I have a problem with displaying maps in page load the map is displayed, but when I want to execute the code on a button click the map is not displayed
Function javascript function AfficherMap() { // alert("ssss"); var mapOptions = { center: new google.maps.LatLng(markers[0].lat, markers[0].lng), zoom: 10,
This is code for searching latitude and longitude . so how to save into database.
function GetLocation() { var geocoder = new google.maps.Geocoder(); var address = document.getElementById("txtAddress").value; geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { var latitude = results[0].geometry.location.lat();
I have written the following code to display multiple markers in google map and i succeeded in it.Now i want to have a drop animation applied to markers and want to drop marker after a specific interval of time.I know i want to call setTimeout method ,but don't know where to call this method to achieve the result
<script type="text/javascript"> window.onload=function(){ if(markers.length>0){ var mapOptions={ center:new google.maps.LatLng(markers[0].lat,markers[0].lng),
