Hi, You can fill datagridView using datareder as following way, public void getdata() { ArrayList arrlist = new ArrayList(); DataGridView myDataGrid = new DataGridView(); sqlConnection.Open(); string query = "select * from Customer"; sqlCommand = new SqlCommand(query, sqlConnection); sqlReader = sqlCommand.ExecuteReader(); while (sqlReader.Read()) { Customerdetails cus = new Customerdetails(); cus.Id =Convert.ToInt32(sqlReader[0].ToString()); cus.Name = sqlReader[1].ToString(); arrlist.Add(cus); } myDataGrid.DataSource = arrlist; myDataGrid.Show(); panel1.Controls.Add(myDataGrid); } Here we have one class name Customerdetails class Customerdetails { private string name; private int id; public string Name { get { return name; } set { name = value; } } public int Id { get { return id; } set { id = value; } } } Hope this will help you. Thanks.
