http://www.webservicex.net/CurrencyConvertor.asmx

Then write following code in Code behind :

using SampleCSharpApplication.net.webservicex.www;

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

Currency cur = new Currency();

Array arr;

arr = System.Enum.GetValues(cur.GetType());

ddlFrom.DataSource = arr;

ddlFrom.DataBind();

ddlTo.DataSource = arr;

ddlTo.DataBind();

}

}

protected void Button1_Click(object sender, EventArgs e)

{

CurrencyConvertor CC = new CurrencyConvertor();

Currency cur = new Currency();

txtResult.Text = CC.ConversionRate((Currency)System.Enum.Parse(cur.GetType(),
ddlFrom.Text), (Currency)System.Enum.Parse(cur.GetType(),
ddlTo.Text)).ToString();

}

<div>

<asp:Literal ID="ltrfrom" runat="server"

Text="Select Currency to convert :"></asp:Literal>

<asp:DropDownList ID="ddlFrom" runat="server"

Style="vertical-align: middle;">

var ToCur = document.getElementById('ddlTo').value;

var strURL = 'http://www.google.com/ig/calculator?hl=en&q=' +

fromCur + '=?' + ToCur
//Url like this " http://www.google.com/ig/calculator?hl=en&q=1USD=?EUR"

var request = new XMLHttpRequest();

request.open("GET", strURL, false);

request.send(null);

if (request.responseText != "") {

document.getElementById('dv').innerHTML =

request.responseText.split('"')[1] + ' = '

+ request.responseText.split('"')[3]

}

}
