Hi Nethra, Here is your solution Untitled Page Text="Saving data in xml format" Width="164px" /> using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { string connStr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; SqlCommand com; SqlDataAdapter sqlda; DataSet ds; string str; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bind(); } } void bind() { SqlConnection con = new SqlConnection(connStr); try { con.Open(); str = "select * from employee"; com = new SqlCommand(str, con); sqlda = new SqlDataAdapter(com); ds = new DataSet(); sqlda.Fill(ds, "employee"); GridView1.DataSource = ds; GridView1.DataMember = "employee"; GridView1.DataBind(); con.Close(); } catch (Exception ex) { Response.Write(ex.Message); } } protected void btn_save_Click(object sender, EventArgs e) { bind(); ds.WriteXml("d:\employee.xml"); Response.Write("Records saved as xml"); } } Thanks If this post helps you mark it as answer

Hi You can try this Solution 2: DataSet ds = new DataSet(); ds.Tables.Add(dt); XmlElement xE = (XmlElement)Serialize(ds); string strXml = xE.OuterXml.ToString(); public XmlElement Serialize(object transformObject) { XmlElement serializedElement = null; try { MemoryStream memStream = new MemoryStream(); XmlSerializer serializer = new XmlSerializer(transformObject.GetType()); serializer.Serialize(memStream, transformObject); memStream.Position = 0; XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(memStream); serializedElement = xmlDoc.DocumentElement; } catch (Exception SerializeException) { } return serializedElement; }

Hi You can try this code.. DataSet ds = GetDataSet(); String xmlString=String.Empty; foreach (DataTable dt in ds.Tables) { xmlString += ConvertDataTableToXML(dt); } public static String ConvertDataTableToXML(DataTable tableToExport) { StringBuilder formattedXML = new StringBuilder(); XmlDocument doc = new XmlDocument(); XmlNode node = doc.CreateNode(XmlNodeType.Element, string .Empty, " root" , null ); DataColumnCollection dtColumns=tableToExport.Columns; foreach (DataRow dataItem in tableToExport.Rows) { XmlElement element = doc.CreateElement( " data" ); foreach (DataColumn thisColumn in dtColumns) { object value = dataItem[thisColumn]; XmlElement tmp = doc.CreateElement(thisColumn.ColumnName); if (value != null ) { tmp.InnerXml = (RegExUtility.HasSpecialCharacter(value.ToString()) ? @" + value.ToString() + " ]]>" : value.ToString()); } else { tmp.InnerXml = string .Empty; } element.AppendChild(tmp); } node.AppendChild(element); } doc.AppendChild(node); return doc.InnerXml; }
