i have one more question

i am trying to refresh datagridview data when i am press refresh button

datagridview.Refresh();

but its not working.

i got it my answer just replace row method's return type with object array and create list object[] inserted of list object.

var list = x.Rows();
if (list.Count != 0)
{
    Object[] ar = list[0];
    var quntity1 = (int) ar[1];
}

and row method

public List<Object[]> Rows()
    {
        List<Object[]> list = new List<Object[]>();
        Cn.Open();
        Dr = Cmd.ExecuteReader();
        while (Dr.Read())
        {
            Object[] array = new Object[Dr.FieldCount];
            Dr.GetValues(array);
            list.Add(array);
        }
        return list;
    }

its work for me
