hi guyz,

private void BindGridForExcel()
        {
            try
            {
                OleDbConnection theConnection = new OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;data source=D:\\DotNet\\Copy of Depreciation working Oct-13.xlsx ;Extended Properties=\"Excel 8.0;HDR=NO;IMEX=1;\"");
                theConnection.Open();
                OleDbDataAdapter theDataAdapter = new OleDbDataAdapter("SELECT * FROM [Working$]", theConnection);
                DataSet theDS = new DataSet();
                DataTable dt = new DataTable();
                theDataAdapter.Fill(dt);
                this.dataGridView1.DataSource = dt.DefaultView;
                theConnection.Close();
            }
            catch (Exception ex)
            { 

            }

        }

        private void BindGridForSql()
        {
            string connectionString = "Data Source=192.168.0.11;Initial Catalog=30_Nov_13;User ID=sa;Password=super";
            string sql = "SELECT * from [@BA_ODPV] ";

            using (var connection = new SqlConnection(connectionString))
            using (var command = new SqlCommand(sql, connection))
            using (var adapter = new SqlDataAdapter(command))
            {
                connection.Open();
                var dataEntry1 = new DataTable();
                adapter.Fill(dataEntry1);
                dataGridView2.DataSource = dataEntry1;
            }

        }

        private void dataGridView1_DoubleClick(object sender, EventArgs e)
        {
            DataGridViewSelectedRowCollection rc = null;
            rc = dataGridView1.SelectedRows;
            sno = rc[0].Cells["F1"].Value.ToString();

NOW HERE I WANT TO SEARCH THE SELECTED DATA IN SNO "sno = rc[0].Cells["F1"].Value.ToString();" IN THE BindGridForSql() GRIDVIEW.. 
THE SNO IS THE BindGridForExcel() GRIDVIEW.. PLZ 
        }
