private DataTable GetData(string query) {
string conString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
MySqlCommand cmd = new MySqlCommand(query);
using (MySqlConnection con = new MySqlConnection(conString)) {
using (MySqlDataAdapter sda = new MySqlDataAdapter())
[Code] ....
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;
}

1) It must get the longitude and latitude from CSV file and it must be a fileupload and loads dynamically using Jquery.

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?

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 () {
[Code] ....
Here is the VB Code I use to call the JS Function:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim cn As New OleDb.OleDbConnection("Provider = Microsoft.ACE.OleDb.12.0;" & _
"Data Source=|DataDirectory|Address Database One Calculation.mdb")
cn.Open()
Dim cmd1 As OleDb.OleDbCommand
Dim sqlconnection1 As String

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.

in our project we need to show the markers on Google map from the database. we have already got the code in which all the markers are displayed for the the places stored in database. But our aim is somewhat different.We need marker on one place that is selected from the database.to elaborate,if we select an area from the dropdownlist that contains names of areas stored in database,then "only" marker on that place must be displayed.Further,selecting the subarea from dropdownlist2 should zoom the map and display a marker on that subarea.so how do we do that? what are the changes required to be made in this code?
