Question

I’m making an asp.net app using visual studio 2010. I have a text field and button that calls a method on the String in the text field.

Enter your address here: <asp:TextBox ID="tb_address" runat="server" ></asp:TextBox>
<asp:Button Text="Submit" runat="server" onclick="GetLatLong" ></asp:Button>

In the C# file for the button, I have my GetLatLong method:

protected void GetLatLong(object sender, EventArgs e)
{
    String address = tb_address.Text;
    String query = "http://maps.googleapis.com/maps/api/geocode/xml?address=";
    address = address.Replace(" ", "+");
    query += address + "&sensor=false";
    XmlDocument xDoc = new XmlDocument();
    xDoc.Load(query);
    String lat = xDoc.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText;
    String lon = xDoc.SelectSingleNode("/GeocodeResponse/result/geometry/location/lng").InnerText;
}

How can I get my lat and lon Strings to display on my html page?

Answer 1

Use <asp:Label />s.

<asp:Label ID="lblLat" runat="server" />
<asp:Label ID="lblLong" runat="server" />

String lat = xDoc.SelectSingleNode("/GeocodeResponse/result/geometry/location/lat").InnerText;
String lon = xDoc.SelectSingleNode("/GeocodeResponse/result/geometry/location/lng").InnerText;
lblLat.Text = lat;
lblLong.Text = lon;
