treeView绑定问题(急)

我将treeview和数据库已经绑定,但是我需要一个效果.单击树控件中的节点,将对应的数值绑定到textbox中等输入文本控件中.
public void GetText(string strId)
      {

         string cmd = "select * from FD_CadSet where cCadID='"+strId+"'";
         SqlConnection _Connection = new SqlConnection(SqlConn);
         _Connection.Open();
         SqlCommand com = new SqlCommand(cmd, _Connection);
         SqlDataReader dr = com.ExecuteReader();
         while (dr.Read())
         {
            this.txb_code.Text = dr[1].ToString();
            this.nu_week.Value = int.Parse(dr[6].ToString());
            this.tb_date.Text = dr[3].ToString(); //日期
            this.nu_day.Value = int.Parse(dr[2].ToString());
            this.tbx_bz.Text = dr[3].ToString();
         }
         dr.Close();
         _Connection.Close();

      }
  private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
      {
         GetText(treeView1.SelectedNode.Text.Substring(2));  //单击绑定
      }

就是这样,却怎么也达不到效果.

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{

textBox1.Text = e.Node.Text.Trim();
}
