Firstly you need to get the values out of your DataReader, then you need to assign them as a row. The simplest way is to add them as an object array: I've added a using statement to make sure the reader is correctly disposed of after use.

// some codes here
using (OleDbDataReader dr = dbCommand.ExecuteReader())
{ 
    while (dr.Read())
    {
        string f1 = dr.GetString("Field1");
        string f1 = dr.GetString("Field2");
        GView.Rows.Add(new object[] {f1, f2});
    }
}
