    using (OdbcConnection DbConnection = new OdbcConnection(ConfigurationManager.AppSettings["ConnectionStr"]))
    {
        DbConnection.Close();
        string cmdText = "SELECT Team_Code,Team_Name FROM team_details WHERE Team_Id=?";
        OdbcCommand cmd = new OdbcCommand(cmdText, DbConnection);
        cmd.Parameters.Add("?Id", OdbcType.Int).Value = Convert.ToInt32(TeamId);
        DbConnection.Open();
        OdbcDataReader DR = cmd.ExecuteReader();
        while (DR.Read())
        {
            tbCode.Text = DR.GetValue(0).ToString();
            tbName.Text = DR.GetValue(1).ToString();
        }

    }

    Use GridViewSelection Event for that

        OnSelectedIndexChanged="Grid_SelectedIndexChanged"


   void Grid_SelectedIndexChanged(Object sender, EventArgs e)
   {

     // Get the currently selected row using the SelectedRow property.
      GridViewRow row = Grid.SelectedRow;

     //Fill textboxes here
     Code.Text =  row.Cells[0].Text;

    }

    Oh yeah this code is for grid.So if you are using datagrid You need to Set the Select CommandField in the Grid so that the SelectedIdexChanged event will fire up

    Here is code sample that will definitely help you
