        public Form1()

        {

            InitializeComponent();

            SqlDataAdapter da = new SqlDataAdapter("Select * from emp", con);

            DataSet ds = new DataSet();

            da.Fill(ds);

            dataGridView1.DataSource = ds.Tables [0];

        }

        private void ToCsV(DataGridView dGV, string filename)

        {

            string stOutput = "";

            // Export titles:

            string sHeaders = "";

            for (int j = 0; j < dGV.Columns.Count; j++)

                sHeaders = sHeaders.ToString() + Convert.ToString(dGV.Columns[j].HeaderText) + "\t";

            stOutput += sHeaders + "\r\n";

            // Export data.

            for (int i = 0; i < dGV.RowCount - 1; i++)

            {

                string stLine = "";

                for (int j = 0; j < dGV.Rows[i].Cells.Count; j++)

                    stLine = stLine.ToString() + Convert.ToString(dGV.Rows[i].Cells[j].Value) + "\t";

                stOutput += stLine + "\r\n";

            }

            Encoding utf16 = Encoding.GetEncoding(1254);

            byte[] output = utf16.GetBytes(stOutput);

            FileStream fs = new FileStream(filename, FileMode.Create);

            BinaryWriter bw = new BinaryWriter(fs);

            bw.Write(output, 0, output.Length); //write the encoded file

            bw.Flush();

            bw.Close();

            fs.Close();

        }

      

        private void btnWord_Click(object sender, EventArgs e)

        {

            SaveFileDialog sfd = new SaveFileDialog();

            sfd.Filter = "Word Documents (*.doc)|*.doc";

            sfd.FileName = "time.doc";

            if (sfd.ShowDialog() == DialogResult.OK)

            {

                //ToCsV(dataGridView1, @"c:\export.xls");

                ToCsV(dataGridView1, sfd.FileName); // Here dataGridview1 is your grid view name

            }

        }

        private void btnExcel_Click(object sender, EventArgs e)

        {

           SaveFileDialog sfd = new SaveFileDialog();

            sfd.Filter = "Excel Documents (*.xls)|*.xls";

            sfd.FileName = "time.xls";

            if (sfd.ShowDialog() == DialogResult.OK)

            {

                ToCsV(dataGridView1, sfd.FileName); // Here dataGridview1 is your grid view name

}

            }

        }
