if (!Page.IsPostBack)
{
//Create object of WSGetCustomerCountryWise Object
localhost.WSGetCustomerCountryWise objGetCustomerCountryWise
= new localhost.WSGetCustomerCountryWise();

DataSet dsCustomer = new DataSet();

// Get the data from Webservice.
XmlElement elem = objGetCustomerCountryWise.GetCustomerCountryWise("USA");

// Load the XML to the Typed DataSet that you want.
XmlNodeReader nodeReader = new XmlNodeReader(elem);
dsCustomer.ReadXml(nodeReader, XmlReadMode.Auto);

GridView1.DataSource = dsCustomer;

GridView1.DataBind();
}
}
