Hi Deepak, Try this... Untitled Page Text="Add Records" /> Text="Show Xml Data" /> using System; using System.Collections; 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; namespace Saving_User_Input_Data_to_an_XML { public partial class _Default : System.Web.UI.Page { static DataSet ds; static DataTable dt; static DataRow dr; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { ds = new DataSet(); ds.ReadXml(MapPath("data.xml")); dt = ds.Tables["student"]; } } protected void btnaddrecords_Click(object sender, EventArgs e) { dr = dt.NewRow(); dr["sid"] = TextBox1.Text; dr["sname"] = TextBox2.Text; dr["smarks"] = TextBox3.Text; dr["saddress"] = TextBox4.Text; dt.Rows.Add(dr); ds.WriteXml(Server.MapPath("data.xml")); Response.Write("Record Successfully Inserted"); clear(); } void clear() { TextBox1.Text = ""; TextBox2.Text = ""; TextBox3.Text = ""; TextBox4.Text = ""; } protected void btn_showdata_Click(object sender, EventArgs e) { DataSet ds = new DataSet(); ds.ReadXml(Server.MapPath("data.xml")); GridView1.DataSource = ds; GridView1.DataBind(); } } } Thanks If this post helps you mark it as answer
