WebService service = new WebService();
string xml = service.FindCountry();\\ getting xml string
DataSet ds = new DataSet();
XmlTextReader reader = new XmlTextReader(new StringReader(xml));
GridView1.DataSource = (ds.ReadXml(reader));
GridView1.DataBind();
**Exception Get while binding gridview**
- Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
From your error description, I suggest you can try the following two methods.
1: ReadXml() returns XmlReadMode which you can't assign as DataSource. You can populate the DataSet and assign it as DataSource in a separate line. You can try the following code.
DataSet ds = new DataSet();
XmlTextReader reader = new XmlTextReader(new StringReader(xml));
ds.ReadXml(reader);
GridView1.DataSource = ds;
GridView1.DataBind();
2: You can refer the following tutorial. It defines a DataTable return type in the method and gridview can be bound by the DataTable which will return from a Web Service.

My web-service returns XML string Response . I have this data to Show it on Grid-view. How to do so ?
request And Response code of my web service
string requestXml2 = requestXml.ToString(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl); byte[] bytes; bytes = System.Text.Encoding.ASCII.GetBytes(requestXml2); request.ContentType = "text/xml; encoding='utf-8'"; request.ContentLength = bytes.Length; request.Method = "POST"; Stream requestStream = request.GetRequestStream(); requestStream.Write(bytes, 0, bytes.Length); requestStream.Close(); HttpWebResponse response; response = (HttpWebResponse)request.GetResponse(); if (response.StatusCode == HttpStatusCode.OK) { Stream responseStream = response.GetResponseStream(); string responseStr = new StreamReader(responseStream).ReadToEnd(); return responseStr ; }This code returns me this XML string
