        }
        DataTable datatable;


        //form load event here data will show in the data gridview
        public void fillGridView()
        {
            try
            {
                //form load event here data will show in the data gridview
                string connectionString = "SERVER=localhost; DATABASE=employee;  USERNAME=root; PASSWORD=ranausman786";
                MySqlConnection objConnection = new MySqlConnection(connectionString);
                objConnection.Open();
                string Query = "SELECT * FROM employee.emp;";
                MySqlCommand objCommand = new MySqlCommand(Query, objConnection);
                MySqlDataAdapter objAdapter = new MySqlDataAdapter();
                datatable = new DataTable();
                objAdapter.SelectCommand = objCommand;
                objAdapter.Fill(datatable);
                dataGridView1.DataSource = datatable;

            }
            catch (Exception)

            //and attached the filter result in to the datagridview
            DataView DV = new DataView(datatable);
            DV.RowFilter = string.Format("Name LIKE '%{0}%'", txtSearch.Text);
            dataGridView1.DataSource = DV;
