Rajkumar R

This below code i had followed to import XML data in to DB
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Insert_data_from_Gridview_database._Default" %>

Untitled Page

Text="Insert Records" />

style="height: 26px" Text="Show Records" />

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 Insert_data_from_Gridview_database

{

public partial class _Default : System.Web.UI.Page

{

string connStr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;

SqlCommand com;

protected void btn_show_Click(object sender, EventArgs e)

{

DataSet reportData = new DataSet();

reportData.ReadXml(Server.MapPath("student.xml"));

GridView1.DataSource = reportData;

GridView1.DataBind();

}

protected void btn_insert_Click(object sender, EventArgs e)

{

foreach (GridViewRow g1 in GridView1.Rows)

{

SqlConnection con = new SqlConnection(connStr);

com = new SqlCommand("insert into student(sid,sname,smarks,saddress) values ('" + g1.Cells[0].Text + "','" + g1.Cells[1].Text + "','" + g1.Cells[2].Text + "','" + g1.Cells[3].Text + "')", con);

con.Open();

com.ExecuteNonQuery();

con.Close();

}

Label1.Text = "Records inserted successfully";

}

One more Help in this..

Tables

student(sid,sname,smarks,saddress) //Here we insert from XML to DB

master_table(sid,sname,age,gender) these r the two tables

Here i want to check one more thing, i.e., if sid in XML file is not in the master_table means then i want to show those in different colour in the grid view while i click the show button.

hi,

review the attached file.

In this sample change

DataSet dtest = reportData.Clone();
DataRow dr = dtest.Tables[0].NewRow();
dr["sid"] = 2;
dtest.Tables[0].Rows.Add(dr);
Insead of this write actual logic to retrive data from database.

hope this help.
