i'm developed google map application and i assign an .. find longitude and latitude opperation to button click event.

so what happens is.. if someone input two cities as input to textboxes, this operation convert those cities to longitude and latitude values and store those values into label.

protected void Button1_Click(object sender, EventArgs e)
        String Strt_Address = TextBox1.Text;
        String End_Address = TextBox2.Text;

        string geocodeUrl1 = string.Format(@"{0}&sensor=false", Strt_Address);

        string geocodeUrl2 = string.Format(@"{0}&sensor=false", End_Address);

        XmlDocument geocodeXmlDoc1 = new XmlDocument();

        XmlDocument geocodeXmlDoc2 = new XmlDocument();

        XmlNamespaceManager XmlMngr1 = new XmlNamespaceManager(geocodeXmlDoc1.NameTable);
        XmlMngr1.AddNamespace("geo", @"");

        XmlNamespaceManager XmlMngr2 = new XmlNamespaceManager(geocodeXmlDoc2.NameTable);
        XmlMngr2.AddNamespace("geo", @"");

        string sLong1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr1).InnerText;
        string sLat1 = geocodeXmlDoc1.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr1).InnerText;

        string sLong2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lat", XmlMngr2).InnerText;
        string sLat2 = geocodeXmlDoc2.DocumentElement.SelectSingleNode(@"//geometry/location/lng", XmlMngr2).InnerText;

        Label1.Text = sLong1 + ", " + sLat1;
        Label2.Text = sLong2 + ", " + sLat2;


        Page.ClientScript.RegisterStartupScript(Page.GetType(), "script",
        "calcRoute()", true);
        // i'm calling my js function from here.......

function calcRoute() {
       // get the travelmode, startpoint and via point from the form
       var travelMode = $("#travelMode option:selected").text();

       var start = document.getElementById('<%= Label1.ClientID %>').value;

you been asking same questions here on google map. I will advise you to learn about the basics, Lets say C# , & javascript. then try google or CP.

try :

Label1.Text.ClientId or Label1.Text

Below is the way you can use Label.Text in JavaScript
var start =<%=Label1.Text%>;
var end = <%=Label2.Text%>;
